The formula for an average of three numbers is (x+y+z)/3. So if V equals the average, then we find the formula
V = (x+y+z)/3
We are now looking for x. We can divide each of the variables in the parentheses by 3, making the formula
V = x/3 + y/3 + z/3
So now bring the unwanted variables to the same side as V.
V - y/3 - z/3 = x/3
Now multiply both sides by 3 to find x.
3V - y - z = x
x = 3V - y - z
You must use Pythagorean theorem, which is
a and b are both legs (the two legs are the sides that form a perpendicular right angle) while c is the hypotenuse (side opposite the right angle)
In this case...
a = y
b = 8
c = 12
^^^Plug these numbers into Pythagorean theorem
Simplify as much as possible
+ 64 = 144
Isolate y by subtracting 64 to both sides
+ (64 - 64) = 144 - 64
= 80
Further isolate y by taking the square root of both sides. This will take away the square from the left side
y =
<<< Can be further simplified
4√5 = y
Hope this helped!

The inverse of a statement is formed as follows:
if not p, then not q.
So, your inverse statement is: “If I don’t live in Charleston, then I don’t live in South Carolina”
