Answer:
X = 1/2
Step-by-step explanation:
The question seems like (6*4x² = 3*4x)
This is a simple algebraic equation
First of all, multiply the coefficient of x by the number on each side.
6*4x² = 3*4x
24x² = 12x
Divide both sides by 12
2x² = x
Divide both sides by x
2x = 1
Solve for x
x = 1/2
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
Answer:
-9
Step-by-step explanation:
Adding a negative 3 is the same as subtracting 3, so if you do -6 - 3 you get -9
50
Age - x
500 - 3x = 350
3x = 150
x=50
