Answer:
50.5
Step-by-step explanation:
2xy+2x^2 And we know x=-2.5 and y=-7.5.
In order of operations, exponents come first.
x^2 = -2.5 * -2.5 = 6.5.
6.5*2=13.
2xy + 13
2x=-5
-5*-7.5 = 37.5
37.5 + 13
50.5
Subtract 985 from 177 since Anna has 177 more songs than Ryelin. Then divide that answer by 2 which gives each one an equal amount then add 177 to one of the answers to get how many each girl has.



So Ryelin has 404 songs downloaded and Anna has 581 songs downloaded.
A. The answer is yes, because the distribution is approximately a bell curve.
