Answer:
P = mgh
P/mg = h
We can divide both sides by mg, since both mass and gravity are being multiplied and not added.
Hope this helps!! :)

Answer:
All real numbers
Step-by-step explanation:
Solve a system of equations by elimination
With the equation given, you can solve for y to get: y =
x - 
Then, substitute this value in on the equation.
x - 5(
x -
) = 6
x - x + 6 = 6
6 = 6
The solution is all real numbers
Answer:

Step-by-step explanation:
95% of 220 is 209 inches so therefor it would be 209 inches.
Answer:
There are two possibilities:
and 
and 
Step-by-step explanation:
Mathematically speaking, the statement is equivalent to this 2-variable non-linear system:


First,
is cleared in the first equation:

Now, the variable is substituted in the second one:

And some algebra is done in order to simplify the expression:


Roots are found by means of the General Equation for Second-Order Polynomials:
and 
There are two different values for
:
