Over the course of a 7 week aerobics class, the people
participating have a combined
weight change of –35 pounds. If
there are 4 people in the class,
what is the average change in
weight per person?

The average weight change is a loss of 8.75 pounds per person.

Step-by-step explanation:

This one was fairly simple, the 7 weeks have nothing to do with it. All you have to do is take the total amount of weight lost, 35 pounds, and divide it by the 4 people in the class. After the calculation, it equals an average loss of 8.75 pounds per person.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
