The following equations are solved in terms of x:
a) 2x - 3 = y
2x = y + 3
x = (1/2)y + 3/2
b) 2 + 2x - 1 = 4y
2x - 1 = 4y
2x = 4y + 1
x = 2y + 1/2
c) 2A + 4x + 3B = 10
4x = 10 - 2A - 3B
x = 5/2 - (1/2)A - (3/4)B
Answer:
49ft
Step-by-step explanation:
4×10=40
6×3/2=9
40+9=49
2 equations, 2 unknowns. Call height H and base B.
From the first sentence:
HB = 216
From the second sentence:
H = ⅔ B
Plug the second into the first and solve for B:
(⅔ B)B = 216
B^2 = 324
B = 18
Plug that back into either of the original 2 equations and solve for H:
H(18) = 216
H = 12
