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:
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)
