Question

When 0.5(20x – 50y + 36) – 0.25(–100x + 40y – 12) is simplified, what is the resulting expression?

Answer 1

D 35x-35y+21

Explanation:

Answer 2

`35x-35y+21` is the resulting expression

Explanation:

Simplify the expression:
`0.5(20x-50y+36)-0.25(-100x+40y-12)`

The distributive property says that:

`a\cdot (b+c) = a\cdot b+ a\cdot c`

Apply the distributive property we have;

`10x-25y+18-(-25x+10y-3)`

remove the open bracket and distribute -1 into each terms.

`10x-25y+18+25x-10y+3`

Combine like terms;

`35x-35y+21`

Therefore, the resulting expression we get,
`35x-35y+21`
