Answer:
hello the correct answer is y=30x+20
Step-by-step explanation:
(X + 4)(X^2 - 1) = x^3 + 4x^2 - x - 4
total the temperatures given
total = 497
divide by how many they gave (7)
497 / 7 = 71
answer is C 71 degrees
Answer:
x + y = 20
1.5x + 5y = 54.50
Solve the equations and get: x = 13 ∧ y = 7
