Step-by-step explanation:

Let's simplify step-by-step.

−x2+2x−2x2−3x+4+x2

=−x2+2x+−2x2+−3x+4+x2

Combine Like Terms:

=−x2+2x+−2x2+−3x+4+x2

=(−x2+−2x2+x2)+(2x+−3x)+(4)

=−2x2+−x+4

Answer:

=−2x2−x+4

Mom's view is that she loses 50 dollars, but gains back 17.85 dollars as change from her daughter.

Olivia's view is that she gained 50 dollars from her mom, spent 32.15 dollars, then gave back the 17.85 change to her mom, so she didn't gain any money.

Mom's point of view: -$50 + $17.85 and Mom's point of view: -$50 + $17.85 are the correct answers, but technically, Olivia still owes her mom 32.15 dollars.

Answer:

r=201

d = 77 1/2

Step-by-step explanation:

6) First multiply left and right by 16, to get rid of the fraction:

r - 25 = 11*16

Now add 25 left and right:

r = 11*16 + 25 = 201

7) Add 5 left and right

2/5 d = 31

multiply by 5/2

d = 31 * 5/2 = 77 1/2
