Answer:
The system of equations is:
x + y = 15
xy = 15
Step-by-step explanation:
solve the first for y and substitute in the second:
y = 15-x
x(15-x) = 15
15x - x� = 15
15x - x� - 15 = 0
-x� + 15x - 15 = 0
x� - 15x + 15 = 0
Answer:
93.15
Step-by-step explanation:
Multiply 230.00 dollars and 0.55 = 126.50
Subtract 230.00 dollars and 126.50 = 103.50

Subtract 103.50 and 10.35 = 93.15
Answer:
d
Step-by-step explanation:
-3(4x+2)-2x
