Answer:
x = 11
∠B = 80°
Step-by-step explanation:
∠A =∠B because they are corresponding angles
8x - 8 = 5x + 25
3x = 33
divide both sides of the equation by 3:
x = 11
∠B = 5(11) + 25 = 80°
Writing equivalent equations help you solve system of equations because it sets it up for being broken down part by part.
Answer:
Step-by-step explanation:

Answer:
14.4 yards
Step-by-step explanation:
Each shirt needs 0.8 yards so 18 shirts needs 18 * 0.8 = 14.4 yards of material.
F(x) = 3x + 8
f(1) = 3 (1) + 8
f (1) = 3 + 8
f(1)= 11
