b y=11.25x

c x=20y

d y=20x

Answer 1

A

Explanation:

Because your not studying

Answer 2

D

Explanation:

simple plug and chug.

Understand that variables are already defined, x=3/4, y=15 meaning that if we plug one of the variables into an equation, we should obtain the other variable's number.

y=20x will result in y=15 when x=3/4 and vice versa.
