Question

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

Answer 1

Answer:

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

Step-by-step 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, $35x-35y+21$

Answer 2

.5(20x-50y+36)-.25(-100x+40y-12)
10x-25y+18+25x-10y+3
35x-25y+18-10y+3
35x-35y+18+3
35x-35y+21
