Pepsi [2]

<h3>Answer: 15 hours (choice D)</h3>

8x = 120

x = 120/8

x = 15

Can someone help me on 4 please

Kay [80]

To solve for x, we need to isolated and to do so, we would have to divide it by 1/6 since it's being multiplied by 1/6. To divide it, we have to do the reciprocal, which is getting any number and flipping it. So, we multiply both sides by 6 and we get 12 on one side and x on the other side.
So, x equals 12
