Question

Edson exercises in sets that are each t minutes long. He does 6 sets of push-ups, 3 sets of pull-ups, and 4 sets of sit-ups. Use an expression to represent the time it takes Edson to exercise as the sum of three different terms. Simplify the expression. Enter your answer in the box. The time it takes Edison to exercise is equal to t.

Answer 1

edson takes 130 minutes of exersise

step by step answer:

10 x 13 = 130

Answer 2

The expression would be 13t.

Step-by-step explanation:

We know that:

• Each set takes t minutes to be done.
• Edson does three types of exercises with different sets: 6, 3 and 4.

Basically, we have to multiply each set by t minutes.

We have:

• 6 sets of push-ups: t + t + t + t + t + t = 6t
• 3 sets of pull-ups: t + t + t = 3t
• 4 sets of sit-ups: t + t + t + t = 4t

The total amount of time considering all sets is 6t + 3t + 4t = 13t. In other words, Edson did 13 sets, if one set takes t minutes, then the 13 sets takes 13t minutes.
