Hello there! Your answer should be 4 mph. Reasoning:
2 = (20 - x) * t
3 = (20 + x ) * t
Time is the same for both equations. Solve for T.
2/(20-x) = 3/(20+x)
the answer is 4 mph.
Please tell me if I was right!
Answer:
12. Since the pool is square, all the sides are equal. The area is length times height, so that means it would be 12 times 12, which is 144. The answer is 12 feet.

Answer:
169.56
Step-by-step explanation:
The formula for finding the volume of a cylinder is: πr²h
First step: Plug in the radius and height: π•3²•6
Second step: Plug 3.14 for π: 3.14•3²•6
Third step: Simplify the equation: 3.14•9•6
Fourth step: Multiple to get your final answer: 3.14•9=28.26•6= 169.56
Answer:
x=2
Step-by-step explanation:
implifying
12x + 8 = 32
Reorder the terms:
8 + 12x = 32
Solving
8 + 12x = 32
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 12x = 32 + -8
Combine like terms: 8 + -8 = 0
0 + 12x = 32 + -8
12x = 32 + -8
Combine like terms: 32 + -8 = 24
12x = 24
Divide each side by '12'.
x = 2
Simplifying
x = 2
