Question

Which expression is equivalent to the expression shown below?

-9.25(2n-3) - 8n

A. -18.5n + 19.75

B. 55.5n+ 27.75

C. 26.5n + 19.75

D. 27.75 -26.5n

Answer 1

option D

Explanation:

Distribute (-9.25) to 2n and (-3). When we multiply (-9.25) and 2n, we get -18.5n and when we multiply (-9.25) and (-3) we get 27.75.

-9.25(2n - 3) - 8n = -9.25*2n - (-9.25) *3 - 8n

= -18.50n + 27.75 -8n

= -18.5n - 8n + 27.75

Combine like terms. Here (-18.5n) and (-8n) are like terms

= -26.5n + 27.75
