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

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 (/fraction{1}{2}x - 2) + 40 (/fraction{3}{4}y - 4)

Now, 30 (/fraction{1}{2}x - 2) + 40 (/fraction {3}{4}y - 4)

= 15x - 60 + 30y - 160

= 15x + 30y - 220

With that being said, the third option is correct i. e. 15 x + 30 y minus 220.
