Question

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

Answer 1

Just like before, we'll want to distribute the terms outside the parentheses to everything inside the parentheses.
In other words, multiply everything in the first set of parentheses by 0.5, then multiply everything in the second set of parentheses by 0.25.
After that, add or subtract any like terms, and you should have your simplified expression

Answer 2

Thats the answer ?

Answer 3

Yup, that would be the most simplified form of the expression, which is what the question asked to find

Answer 4

ummm.... ? i dont understand

Answer 5

answer choices

10x-25y+18-25x+10y-3
-15x-15y+15
-10x+25y+18+25x-10y+3
35x-35y+21

Answer 6

If you multiply everything in the first parentheses by 0.5, you'd get 10x - 25y + 18.
I think that should help, for starters.
Don't forget to add and subtract all like terms.

Answer 7

Now i understand !
