At a local fitness center, members pay a $10 membership fee and $5 for each aerobics class. Nonmembers pay $6 for each aerob

One way to solve it is writing two equations based on the info so

y = 5x + 10 for members
y = 6x for nonmembers

(the + 10 isn't included in the second equation because nonmembers won't pay a membership fee)

and to find their intersection point (where the values will be the same), you just set them equal to each other:

5x + 10 = 6x

subtract 5x

x = 10 classes

How do you simplify this problem

vampirchik [111]

Reduce the fraction with 2
$\frac{2 \times x {}^{ - 2} y {}^{3}z {}^{ - 1} }{xy} \\ \\ \frac{3y {}^{2}z {}^{ - 1} }{x {}^{3} } \\ \\ \frac{3y {}^{2} }{x {}^{3} z}$
