I am sure it would be 27 percent
Ann-x
Cori-3x
3x+x=124
4x=124
divide both sides by 4
x=31 now plug it in and you get
Ann-31
Cori-31×3=93
Ann spent 31$
Cori spent 93$
Answer:
D
Step-by-step explanation:
That symbol pie is 3.14
It 7 you just divide by two
For these kinds of expressions use FOIL (first, outside, inside, last).
-2x • 9x = -18x^2
-2x • -3y = 6xy
8y • 9x = 72 xy
8y • -3y = -24y^2
Now combine them all:
-18x^2 + 78xy - 24y^2
