Solve each equation for the ind 2. 2(x-7)=10

SVETLANKA909090 [29]

Answer:

x= 12

Step-by-step explanation:

2(x-7) = 10

Distribute the 2. 2x-14 = 10

Add the 14 onto both sides to cancel it out on the original side and following the rules- the same must be done to the other side. 2x-14 (+14) = 10+14 -----> 2x = 24

Divide both sides by 2 to get the X alone. 2x/2 = 24/2 ---------> x= 12

During rush hour, Geoffrey counted that he had to stop at 8 different red lights. He went through a total of 25 intersections. W

I think the answer is 32% because if you turn 32% into a decimal (which would be 0.32) then multiply it by 25 you would get 8. Which then means if he stopped 8 times and went through 25 intersections then he stopped at 32% of the intersections. I hope this helps :)
