Answer:
3) 5/2
Step-by-step explanation:
2y = 5x + 4
y = 5/2x + 2
slope = 5/2
(y = mx + b, m being slope, b being y intercept)

C= 2*3.14*20

First, we can do distributive property.
-3(n + 8) = 15
-3 x n = -3n, -3 x 8 = -24
So we have, -3n + -24 = 15
Minus -24 on both sides of the equal sign.
-3n + -24 - -24 = 15 - -24
-3n = 39
Divide 3 on both sides.
-3n/-3 = 39/-3
n = -13
Hope i helped!! :D
