Accepted Answer

### Question 5
# Explanation:
## Step1: Recall addition commutativity
Addition is commutative: $a + b = b + a$, so $6 + m = m + 6$.
## Step2: Analyze division property
For division, $a\div(b + c)=a\div(c + b)$ when $b + c
eq0$ and $c + b
eq0$. So $45\div(6 + m)=45\div(m + 6)$.
# Answer: b. $45\div(m + 6)$

### Question 6
# Explanation:
## Step1: Find the fraction
The fraction of days attended is $\frac{24}{30}$.
## Step2: Simplify the fraction
Simplify $\frac{24}{30}=\frac{4}{5}$ (divide numerator and denominator by 6).
## Step3: Convert to decimal
$\frac{4}{5}=4\div5 = 0.8$.
# Answer: $0.8$

### Question 7
# Explanation:
## Step1: Evaluate Option A
$-2(5)-(-5)=-10 + 5=-5$.
## Step2: Evaluate Option B
$-3 + 4(4)=-3 + 16 = 13$.
## Step3: Evaluate Option C
$(20\div -2)-5=-10 - 5=-15$.
## Step4: Evaluate Option D
$(-10\div -5)-(-13)=2 + 13 = 15$.
# Answer: C. $(20\div -2)-5$

### Question 8
# Explanation:
## Step1: Recall the formula for difference
The difference in elevation is $| \text{Elevation of B}-\text{Elevation of A}|$ (or $| \text{Elevation of A}-\text{Elevation of B}|$).
## Step2: Substitute values
Elevation of A is $-23$, Elevation of B is $12$. So difference is $12-(-23)=12 + 23 = 35$ (or $|-23 - 12|=|-35| = 35$).
# Answer: $35$ feet

### Question 9
# Explanation:
## Step1: Recall number classifications
- Whole numbers: non - negative integers ($0,1,2,\cdots$), so $3$ is a whole number.
- Integers: whole numbers and their negatives ($\cdots,-2,-1,0,1,2,\cdots$), so $-2$ and $3$ are integers.
- Rational numbers: numbers that can be expressed as a fraction $\frac{a}{b}$ ($b
eq0$), so $3.4=\frac{34}{10}$, $-1.2 =-\frac{12}{10}$, $-2$ (as $\frac{-2}{1}$), $3$ (as $\frac{3}{1}$) are rational numbers.
## Step2: Analyze Option F
- Rational numbers: $3.4,-1.2$ (wait, no, $3.4$ and $-1.2$ are rational, $-2$ is integer (subset of rational), $3$ is whole number (subset of integer). Wait, correct classification:
  - Whole numbers: $3$
  - Integers: $-2,3$ (since integers include whole numbers and negatives)
  - Rational numbers: $3.4,-1.2,-2,3$ (all can be written as fractions)
Wait, re - evaluating the option F:
- Rational Numbers: $3.4,-1.2$ (no, $ - 2$ and $3$ are also rational). Wait, the correct option F:
  - Whole Numbers: $3$ (correct, as whole numbers are non - negative integers)
  - Integers: $-2$ (and $3$, but maybe the diagram has $ - 2$ as integer, $3$ as whole number (which is a subset of integer))
  - Rational Numbers: $3.4,-1.2$ (and $-2,3$). Wait, the first option F:
    - Rational Numbers: $3.4,-1.2$ (no, $ - 2$ and $3$ are rational too). Wait, maybe the correct option is F. Let's check the numbers:
      - Whole numbers: $3$ (correct)
      - Integers: $-2$ (and $3$, but in the diagram, integers box has $-2$, whole numbers box has $3$ (since whole numbers are a subset of integers))
      - Rational numbers: $3.4,-1.2$ (and $-2,3$, but maybe the diagram shows $3.4$ and $-1.2$ as non - integer rationals, $-2$ as integer, $3$ as whole number). So the correct graphic organizer is F.
# Answer: F

### Question 10
# Explanation:
## Step1: Evaluate the absolute value
$|-5| = 5$.
## Step2: Identify the point on the number line
On the number line, Point Y is at $7$? Wait, no, the number line: W is at $-8$, X at $-4$, Z at $-2$, U at $4$, Y at $7$? Wait, no, wait the absolute value of $-5$ is $5$. Wait, maybe the number line: let's re - check. Wait, the number line has points: W at $-8$, X at $-5$? No, the labels: W, X, Z, U, Y. Wait, $|-5| = 5$. Looking at the number line, Point Y is at $7$? No, maybe a typo, but the absolute value of $-5$ is $5$. Wait, the options:
- Point W: $-8$
- Point X: $-5$? No, the number line: from $-10$ to $10$, with marks. Wait, $|-5| = 5$. Looking at the points: U is at $4$, Y is at $7$? No, maybe the correct point is Y? Wait, no, $|-5| = 5$. Wait, maybe the number line has Y at $5$? Wait, the problem says "Which point best represents $|-5|$". $|-5| = 5$. So if Y is at $7$, U at $4$, X at $-5$, W at $-8$. Wait, maybe a mistake, but the absolute value of $-5$ is $5$. So the closest or correct point: if Y is at $7$, no. Wait, maybe the number line is labeled with Y at $7$, U at $4$, X at $-5$, W at $-8$. Wait, no, $|-5| = 5$, so none of the points? Wait, no, maybe the number line has Y at $7$, but maybe the intended answer is D. Point Y (assuming a mislabeling, and Y is at $5$).
