Answer:
3x^2 + 2x - 3y - 10
Step-by-step explanation:
7y + 2x - 10y +3x^2 - 10x
I like to put it in order starting with exponents like this
3x^2 + 2x - 10x + 7y - 10y
then combine like terms
3x^2 - 8x - 3y
that is as simplified as it gets.

Answer:
Step-by-step explanation:
The answer is $27.23 for the commission
Work out problem:
495×5.5%=27.225
So you round that off to 27.23
When working with a problem with percentages, you always multiple to figure out how you got your and what is your answer.
21 and 7/8-8 and 5/12
remember that 21 and 7/8=21+7/8 and 8 and 5/12=8+5/12 so
21+7/8-(8+5/12)
21+7/8-8-5/12
21-8+7/8-5/12
13+7/8-5/12
so 7/8 and 5/12
make bottom number the same
multiply 7/8 by 12/12 and multiply 5/12 by 8/8
7/8-5/12=84/96-40/96=(84-40)/96=44/96=11/24
so the answer is
13 and 11/24
