2. −52÷(−4)
3. −27÷3
4. −36÷2
5. 56÷(−8)
6. −24÷(−3)
7. $\frac{-18}{6}$
8. $\frac{25}{-5}$
9. $\frac{-16}{-4}$
10. $\frac{-66}{11}$

evaluate the expression.

1. 32÷(−2)+(−25)÷5
2. 4⋅(−3)+12÷(−4)
3. you improve your time running a course by 5 seconds in week one, by 3 seconds in week two, and by 4 seconds in week three. what is the mean weekly change in your running time?

Explanation:

Step1: Calculate division problems

1. $6\div(-3)=- 2$
2. $-52\div(-4) = 13$
3. $-27\div3=-9$
4. $-36\div2=-18$
5. $56\div(-8)=-7$
6. $-24\div(-3)=8$
7. $\frac{-18}{6}=-3$
8. $\frac{25}{-5}=-5$
9. $\frac{-16}{-4}=4$
10. $\frac{-66}{11}=-6$

Step2: Evaluate expression 11

$32\div(-2)+(-25)\div5=-16 - 5=-21$

Step3: Evaluate expression 12

$4\times(-3)+12\div(-4)=-12-3=-15$

Step4: Calculate mean for problem 13

The changes are 5, 3, 4. Mean $=\frac{5 + 3+4}{3}=\frac{12}{3}=4$
