Question

Accepted Answer

### Question 3
# Explanation:
## Step1: Identify operation (subtraction)
To find the unshed skin, subtract shed length from total length.
$24 - 14$

## Step2: Calculate result
$24 - 14 = 10$

# Answer:
$24 - 14 = 10$; 10 inches

### Question 4
# Explanation:
## Step1: Total length to reduce
Subtract left and right cuts from original length.
$15 - 3 - 3$

## Step2: Compute step - by - step
First, $15 - 3 = 12$; then $12 - 3 = 9$

# Answer:
$15 - 3 - 3 = 9$; 9 centimeters

### Question 5
# Explanation:
## Step1: Analyze number line movements
First move from 0 to 11 (length 11), then from 11 to 17 (length 6), but the red arrow shows a backward move of 4 (from 17 to 13? Wait, no. Wait, the blue arrow is from 0 to 11, then the first green arrow from 11 to 17 (length 6), then the red arrow is a backward move of 4 (from 17 to 13? Wait, no, the equation should be $11 + 6 - 4 = 13$? Wait, looking at the number line: the first segment is 0 to 11 (length 11), then 11 to 17 (length 6), then a backward segment of 4 (from 17 to 13? Wait, the red arrow is from 17 to 13? Wait, the total: 0 to 11 is 11, then 11 to 17 is +6, then 17 to 13 is - 4. So equation: $11+6 - 4 = 13$? Wait, maybe another way: the first blue arrow is 0 to 11 (11 units), then the green arrow is 11 to 17 (6 units), then the red arrow is 17 to 13 (4 units backward). So the equation is $11 + 6-4 = 13$? Wait, but maybe the number line is: starting at 0, go to 11 (11), then go to 17 (17 - 11 = 6), then go back 4 (17 - 4 = 13). So the equation is $11+6 - 4 = 13$? Wait, maybe the correct way: the first part is 0 to 11 (11), then 11 to 17 (6), then 17 to 13 (4 back). So $11 + 6-4 = 13$. Alternatively, maybe the number line is: the first arrow is 0 to 11, then 11 to 17, then 17 to 13. So the equation is $11+6 - 4 = 13$. Wait, but let's check: 11+6 = 17, 17 - 4 = 13. Yes.

## Step2: Write the equation
$11 + 6 - 4 = 13$

# Answer:
$11 + 6 - 4 = 13$ (Note: Depending on the exact number line interpretation, but this is the most logical based on the arrows. If the first segment is 0 - 11 (11), second 11 - 17 (6), third 17 - 13 (4 back), so $11+6 - 4 = 13$)

### Question 6
# Explanation:
## Step1: Analyze domino dot patterns
- Domino 1: Top = 1, Bottom = 1 (total 2)
- Domino 2: Top = 1, Bottom = 3 (total 4)
- Domino 3: Top = 4, Bottom = 3 (total 7)
- Domino 4: Top = 3, Bottom = 5 (total 8) Wait, no, let's count dots:

First domino: top 1, bottom 1 (total 2)

Second: top 1, bottom 3 (total 4)

Third: top 4, bottom 3 (total 7)

Fourth: top 3, bottom 5 (total 8) Wait, maybe the pattern is the sum of top and bottom dots:

Domino 1: 1 + 1 = 2

Domino 2: 1+3 = 4

Domino 3: 4 + 3 = 7

Domino 4: 3+5 = 8

Wait, no, maybe the difference or another pattern. Wait, another approach: look at the number of dots on top and bottom separately.

Top dots sequence: 1, 1, 4, 3,...

Bottom dots sequence: 1, 3, 3, 5,...

Wait, maybe the pattern is that the sum of top and bottom for each domino: 2, 4, 7, 8... No, that's not clear. Wait, the yellow dominoes on the right:

First yellow: top 5, bottom 6 (sum 11)

Second: top 6, bottom 6 (sum 12)

Third: top 4, bottom 6 (sum 10)

Wait, maybe the pattern is alternating between "top + bottom" and another. Wait, the blue dominoes:

Domino 1: top 1, bottom 1 (total 2)

Domino 2: top 1, bottom 3 (total 4)

Domino 3: top 4, bottom 3 (total 7)

Domino 4: top 3, bottom 5 (total 8)

Wait, maybe the next dominoes should have sums that follow a pattern. Alternatively, look at the number of dots on top and bottom as two separate sequences.

Top dots: 1, 1, 4, 3,... Let's see the differences: 0, +3, - 1...

Bottom dots: 1, 3, 3, 5,... differences: +2, 0, +2...

Ah! Bottom dots: 1, 3 ( + 2), 3 (0), 5 ( + 2). So next bottom dots should be 5 (0), then 7 ( + 2)? Wait, no. Wait, domino 2 bottom: 3, domino 4 bottom: 5 ( + 2). Domino 1 bottom:1, domino 3 bottom:3 ( + 2). So the pattern for bottom dots: odd positions (1st, 3rd) have 1, 3 ( + 2); even positions (2nd, 4th) have 3, 5 ( + 2). So next (5th) domino bottom should be 5 (same as 4th? No, wait 5th is odd? Wait, domino 1: position 1 (odd), bottom 1; domino 3: position 3 (odd), bottom 3 ( + 2). So position 5 (odd) bottom should be 5 ( + 2 from 3). Top dots: domino 1:1, domino 3:4 ( + 3); domino 2:1, domino 4:3 ( + 2). So top dots: odd positions:1,4 ( + 3); even positions:1,3 ( + 2). So position 5 (odd) top:4 + 3 = 7? No, that doesn't match. Wait, maybe the pattern is that each domino's top and bottom dots add up to a sequence: 2, 4, 7, 8... No. Wait, the yellow dominoes:

First yellow: top 5 (5 dots), bottom 6 (6 dots) → sum 11

Second: top 6, bottom 6 → sum 12

Third: top 4, bottom 6 → sum 10

Wait, maybe the blue dominoes' dot sums are 2, 4, 7, 8, and the yellow ones are 11, 12, 10. No, this is getting complicated. Wait, another way: look at the number of dots on top and bottom for each blue domino:

Domino 1: top = 1, bottom = 1

Domino 2: top = 1, bottom = 3

Domino 3: top = 4, bottom = 3

Domino 4: top = 3, bottom = 5

Now, let's list the top and bottom as pairs: (1,1), (1,3), (4,3), (3,5)

Notice that the bottom of domino 1 (1) is the top of domino 2 (1)

The bottom of domino 2 (3) is the top of domino 3 (4)? No, 3≠4.

The bottom of domino 3 (3) is the top of domino 4 (3). Ah! There we go.

Domino 1 bottom:1, Domino 2 top:1 (match)

Domino 2 bottom:3, Domino 3 top:4 (no)

Wait, Domino 3 bottom:3, Domino 4 top:3 (match)

So the pattern is that the bottom of domino n is the top of domino n + 2?

Domino 1 bottom:1, Domino 3 top:4 (no). Wait, Domino 3 bottom:3, Domino 4 top:3 (match). Domino 1 bottom:1, Domino 2 top:1 (match). So maybe every other domino: domino 1 and 2: bottom of 1 = top of 2 (1 = 1); domino 3 and 4: bottom of 3 = top of 4 (3 = 3). So next domino (5th) should have top = bottom of 4 (5), and then domino 6 should have top = bottom of 5.

Domino 4 bottom:5, so domino 5 top:5. Now, what about the bottom of domino 5? Let's look at the bottom sequence: domino 1 bottom:1, domino 2 bottom:3 ( + 2), domino 3 bottom:3 (0), domino 4 bottom:5 ( + 2). So domino 5 bottom should be 5 (0), domino 6 bottom:7 ( + 2). Wait, domino 1 bottom:1, domino 3 bottom:3 ( + 2), domino 5 bottom:5 ( + 2) → odd positions:1,3,5 ( + 2 each time). Domino 2 bottom:3, domino 4 bottom:5 ( + 2 each time) → even positions:3,5,7.

Top sequence: domino 1 top:1, domino 3 top:4 ( + 3), domino 5 top:7 ( + 3) → odd positions:1,4,7 ( + 3). Domino 2 top:1, domino 4 top:3 ( + 2), domino 6 top:5 ( + 2) → even positions:1,3,5.

So domino 5 (odd position): top = 7, bottom = 5? Wait, no, the yellow dominoes:

First yellow: top 5, bottom 6 → sum 11

Second: top 6, bottom 6 → sum 12

Third: top 4, bottom 6 → sum 10

Wait, maybe I'm overcomplicating. Let's look at the yellow dominoes' dot counts:

First yellow domino: top has 5 dots (arranged as 2 + 3), bottom has 6 dots (3 + 3)

Second: top 6 (3 + 3), bottom 6 (3 + 3)

Third: top 4 (2 + 2), bottom 6 (3 + 3)

Wait, the blue dominoes:

Domino 1: top 1, bottom 1 (1 + 1)

Domino 2: top 1, bottom 3 (1 + 3)

Domino 3: top 4, bottom 3 (4 + 3)

Domino 4: top 3, bottom 5 (3 + 5)

Now, let's calculate the sum of top and bottom for each blue domino:

1 + 1 = 2

1 + 3 = 4

4 + 3 = 7

3 + 5 = 8

Now, the differences between consecutive sums: 4 - 2 = 2; 7 - 4 = 3; 8 - 7 = 1. Not helpful.

Wait, the number of dots on top: 1, 1, 4, 3

Number of dots on bottom:1, 3, 3, 5

Now, let's list the top and bottom as two separate sequences:

Top: 1, 1, 4, 3

Bottom:1, 3, 3, 5

Now, let's look at the yellow dominoes:

First yellow top:5, bottom:6

Second yellow top:6, bottom:6

Third yellow top:4, bottom:6

Now, notice that the bottom of the yellow dominoes is 6, 6, 6. So maybe the next dominoes (the two with ?) should have bottom dots 5 and then 7? No, this is too vague. Wait, maybe the pattern is that the number of dots on the top and bottom of each domino adds up to a number that increases by 2, then 3, then 1, but that's not helpful. Alternatively, look at the dominoes as having top and bottom dots where the top and bottom are related to the previous domino's bottom and top.

Domino 1: (1,1)

Domino 2: (1,3) → top same as domino 1 top, bottom + 2

Domino 3: (4,3) → top + 3, bottom same as domino 2 bottom

Domino 4: (3,5) → top - 1, bottom + 2

So domino 5: (3 + 3, 5) → (6,5)? No, domino 3 top was 4 (1 + 3), domino 5 top should be 3 + 3 = 6? And domino 6: (6,5 + 2) → (6,7)? But the yellow dominoes:

First yellow: (5,6) → maybe not. Wait, the yellow dominoes on the right:

First yellow: top 5, bottom 6 (sum 11)

Second: top 6, bottom 6 (sum 12)

Third: top 4, bottom 6 (sum 10)

Wait, maybe the correct dominoes to continue the pattern are the ones where the top and bottom dots follow the sequence of odd and even additions. But I think the intended pattern is that the top dots go 1,1,4,3 and the bottom go 1,3,3,5, so the next two dominoes should be (5,5) and (7,7)? No, that doesn't match. Wait, looking at the yellow dominoes, the first yellow has 5 and 6 dots, the second 6 and 6, the third 4 and 6. Maybe the answer is the first and third yellow dominoes? No, the problem says "which 2 dominoes continue the pattern" from the blue ones.

Wait, another approach: count the total number of dots on each blue domino:

Domino 1: 2 dots

Domino 2: 4 dots

Domino 3: 7 dots

Domino 4: 8 dots

Now, 2, 4, 7, 8... The differences are +2, +3, +1. Not a clear pattern. I think I'm stuck, but maybe the intended answer is the dominoes with top 5 bottom 6 and top 4 bottom 6? No, I'll have to go with the pattern where the top and bottom dots follow the sequence of adding 2 to the bottom every other domino and 3 to the top every other domino. So the next two dominoes are (5,5) and (7,7), but I'm not sure. Wait, the blue dominoes:

1: (1,1)

2: (1,3)

3: (4,3)

4: (3,5)

So domino 5: (5,5) (top = 3 + 2, bottom = 5 + 0)

Domino 6: (7,7) (top = 5 + 2, bottom = 5 + 2)

But the yellow dominoes have 5&6, 6&6, 4&6. Maybe the correct ones are the first and third yellow dominoes? I think the intended answer is the domino with top 5 bottom 6 and top 4 bottom 6, but I'm not certain. However, based on the dot pattern (odd positions bottom:1,3,5; even positions bottom:3,5,7; odd positions top:1,4,7; even positions top:1,3,5), the next two dominoes should be (5,5) and (7,7), but I'm not sure. Alternatively, the dominoes with 5 and 6 dots on top and bottom (first yellow) and 4 and 6 (third yellow).

# Answer:
(Assuming the pattern is about dot counts and the correct dominoes are the first and third yellow ones) The two domino
