Answer 1

If you would like to know which expression represents the amount of time Joe exercises, you can calculate this using the following steps:

Keith ... x hours a week
Troy ... three hours less than Keith: x - 3
Joe ... two times more than Troy: 2 * (x - 3)

The correct result would be D) 2 * (x - 3).

Answer 2

Answer:

The answer is D because

Step-by-step explanation:

Keith = x

And Troy exercises three hours less than Keith. Thus,

Troy = x - 3

And Joe exercises two time more than Troy. Thus,

Joe = 2(x - 3)
