Answer:
70
Step-by-step explanation:
Solving for b, we have the equation A(b)=12*(b+9)/2 - we cancel out 12 and the 1/2 to get 6(b+9)=A(b) and get 6b+54=A(b). Subtract 54 from both sides to get 6b=A(b)-54 and divide both sides by 6 to get b=A(b)/6-9 = A
The answer is 26.19. It’s 100% right.
8x + 4y = -20
4y = -20 - 8x
y = -5 -2x
-4x - 8y = -20
-4x - 8(-5-2x) = -20
-4x + 40 + 16x = -20
12x = -60
x = -5
8(-5) + 4y = -20
-40 + 4y = -20
4y = 20
y = 5
