Question

Which expression is equivalent to 30 (one-half x minus 2) + 40 (three-fourths y minus 4)? 45 x y minus 220 15 x minus 30 y minus 220 15 x + 30 y minus 220 15 x + 30 y minus 64

Answer 1

Step-by-step explanation: C.

Answer 2

The third option is correct i.e. 15 x + 30 y minus 220.

Explanation:

We have to choose expression from the option that is equivalent to

`30((1)/(2)x - 2) + 40((3)/(4)y - 4)`

Now,
`30((1)/(2)x - 2) + 40((3)/(4)y - 4)`

= 15x - 60 + 30y - 160

= 15x + 30y - 220

Therefore, the third option is correct i.e. 15 x + 30 y minus 220. (Answer)
