At a local fitness center, member pay a $10 membership fee and $3 for each aerobics class. Nonmembers pay $4 each aerobics class. For what number of aerobics classes will cost for members and nonmembers be the same?

12 classes members and nonmembers have to pay the same amount.

Step-by-step explanation:

6x=5x+12

Subtracting both sides by 5x, we get

x=12

70,000 + 6,000 + 800 + 30

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
