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.
Edson does three types of exercises with different sets: 6, 3 and 4.
Basically, we have to multiply each set by <em>t</em> minutes.
We have:
6 sets of push-ups: <em> t + t + t + t + t + t = 6t</em>
3 sets of pull-ups: <em>t + t + t = 3t</em>
4 sets of sit-ups: <em>t + t + t + t = 4t</em>
The total amount of time considering all sets is <em>6t + 3t + 4t = 13t. </em>In other words, Edson did 13 sets, if one set takes <em>t </em>minutes, then the 13 sets takes <em>13t </em>minutes.

The theory of plate tectonics tells us exactly where the continents were before Pangaea divided. D. The theory of plate tectonics shows that Pangaea was impossible, but .
I think it means that your putting in an equal amount of force on each hand because it's the same brain that controls what you do. I think that's what it means, not entirely sure but hope this helps
