Question

Which expression is equivalent to 30 (1/2x - 2) +40 (3/4y-4)? (will add pic)

Answer 1

Answer:

C

Step-by-step explanation:

Given

30( $\frac{1}{2}$ x - 2) + 40( $\frac{3}{4}$ y - 4)

Multiply each of the terms in the first parenthesis by 30 and multiply each of the terms in the second parenthesis by 40.

= 15x - 60 + 30y - 160

= 15x + 30y - 220 → C
