Sally wants to calculate how fast her little brother can run. What information does she need to know?

If she's willing to calculate within mph, she needs to know a certain distance her brother can run, and how long it takes to run that distance.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
