Answer:
b = 3Vh
Step-by-step explanation:
When they ask to solve for b, you are essentially rearranging the equation so that b is alone on one side.
V = 1/3bh
(V)(3) = (1/3bh)(3)
3V = bh
(3V)/h = (bh)/h
3Vh = b
b = 3Vh
Answer:
I think its 4 and 5
Step-by-step explanation:
Answer: this is wrong. The final answer should be x - 4y = 8
Step-by-step explanation:
y = 1/4x + 2
We'll first isolate the constant
-1/4x + y = 2
We remove the fraction by multiply through both sides of the equation
-4
x - 4y = 8
Answer:
14 years old
Explanation:
Use this system of equations if G=George and J=Jeannie:
G-12=J
50=(G+5)+(J+5)
So, change second equation becomes
40-G=J
Then use substitution:
G-12=40-G
2G=52
G=26
Then, to find Jeannie’s age, go back to one of the equations and substitute G.
26-12=J
So, J=14
Jeannie is currently 14 years old.
