Alexander Bates · Answer 1

He worked 7.5 hours

Step-by-step explanation:

Let's set up an equation!

125 = 14x + 20.

We are trying to find x!

Let's subtract 20 on both (maintain equality) sides

105 = 14x

Now let's divide both (maintain equality) sides by 14 to get!

x = 7.5

Let's check!

125 = 14 * 7.5 + 20

125 = 105 + 20

125 = 125 YES

So, x = 7.5
