I think the answer is:
X=3
Y=-2
Answer:
A
Step-by-step explanation:
You switch the y and x and solve for y.
y = 2x + 5
becomes
x = 2y + 5
Subtract 5 on both sides.
x - 5 = 2y
Divide 2 on both sides.
(x - 5) / 2 = y
Answer:
21
Step-by-step explanation:
so the relationship is that the music is ten times the commercials so, divide 210 by 30 and times that number by 3 210/30= 7, 7'3=21
