Each individual act is 5 minutes.

b) How long is each group act?

Each group act is 10 minutes.

9. Discussion.

Discuss the reasonableness of your answers. (2 points: 1 point for each part)

a) Is the answer you found reasonable? Does it seem like enough time?

Yes, I believe the answer if found was reasonable. I think it is reasonable because 5 minutes seems to be enough time for an act with one person, and 10 minutes seems to be enough time for an act with multiple people.

Which expression is a trinomial of degree 1?<br><br>6 + x – y<br><br>3x – y
VikaD [51]
The correct answer is 6+x-y.

This is because the other answer choice is a binomial and not a trinomial (which contains three terms). A term is always separated by - or + signs.
