Question

minute 4
name

1. 1, 5, 9, 13, __, , __
2. $10 - 4 \cdot 2 =$
3. $\frac{18}{3} =$
4. $84 \div 1 =$
5. does ellen spend more time on homework or sports? ____
6. $4 \cdot 3 + 5 \cdot 1 =$

for questions 7–10, use $a = 2$, $b = 3$, and $c = 6$.

1. $a + b =$
2. $ac =$
3. $\frac{c}{a} =$
4. $2b =$

Explanation:

Step1: Identify sequence pattern

The sequence increases by 4: $1+4=5$, $5+4=9$, $9+4=13$

Step2: Calculate next 3 terms

$13+4=17$, $17+4=21$, $21+4=25$

Step3: Apply order of operations

Multiply first: $4 \cdot 2=8$, then subtract: $10-8=2$

Step4: Simplify the fraction

$\frac{18}{3}=18\div3=6$

Step5: Divide by 1 rule

Any number ÷1 = itself: $84\div1=84$

Step6: Compare pie chart segments

The "sports" segment is larger than "homework"

Step7: Apply order of operations

Multiply first: $4\cdot3=12$, $5\cdot1=5$; add results: $12+5=17$

Step8: Substitute values for $a+b$

$a=2$, $b=3$: $2+3=5$

Step9: Substitute values for $ac$

$a=2$, $c=6$: $2\cdot6=12$

Step10: Substitute values for $\frac{c}{a}$

$c=6$, $a=2$: $\frac{6}{2}=3$

Step11: Substitute values for $2b$

$b=3$: $2\cdot3=6$
