You need to isolate the variable (x) by performing the opposite operation.
Since 3 is multiplied by x, the opposite would be dividing by 3. What you do on one side you do on the other side, so you would need to divide -12 by 3 as well.
In your case, the answer is B
Answer:
N-12 = 20
N=32
Step-by-step explanation:
Difference means subtract, is means equals
N-12 = 20
Add 12 to each side
N-12+12 =20+12
N = 32
Answer:
$16
Step-by-step explanation:
You would just multuply the amount of time and the amount of money it costs.
Answer:
Step-by-step explanation:
Formula
V pi * r^2 * h
Givens
r = 3 m
h = 6 m
pi = 3.14 when used.
Solution
V = pi r^2 * h
V = pi * 3^2 * 6
V = 9 * 6 * pi
V = 54 * pi Volume in terms of pi
V = 54*3.14 Volume using a value for pi
V = 169.56 to the hundred's place.
No it cant be because a number with a repeating decimal is irrational, rational numbers are integers that can be expressed as a fraction<span />
