Answer:
E) -3, 5
Step-by-step explanation:
x – 15 / x = 2
x^2 - 15 = 2x
x^2 - 2x - 15 = 0
(x - 5)(x + 3) = 0
x - 5 = 0; x = 5
x + 3 = 0; x = -3
Solutions: -3, 5
Answer:
x = 17
Step-by-step explanation:
Those two are alternate angles so they are equal.
4x - 10 = 58
4x = 58 + 10
= 68
x = 68 ÷ 4
x = 17
X+y=1770
9x+4y=14680
x=1770-y
9(1770-y)+4y=14680
15930-9y+4y=14680
-5y=-1250
5y=1250
y=1250/5
y=250
