Solve for x: 5|2x − 2| + 8 = 18.

x = 2, x = −2
x = −2, x = 0
x = 2, x = 0
x = 0, x = 1 over 2

Remember
|x| makes x posotive
5|2x-2|+8=18
minus 8 both sides
5|2x-2|=10
divide both sides by 5
|2x-2|=2
assume
2x-2=2 and 2x-2=-2

2x-2=2
add 2
2x=4
divide 2
x=2

2x-2=-2
add 2
2x=0
x=0

x=0 or x=2

In this question, we can determine Maggie car initial speed (15m/s), final speed(0m/s) and the time her car moves (2.5s). Then to calculate the distance she travels, we need to multiply the average speed with time. The equation would be:

Distance traveled= (initial speed+final speed)/2 x time
Distance traveled= (0m/s + 15m/s)/2 x 2.5 second= 7.5m/s x 2.5s= 18.75m
