What is -121-4x=39+6x

1 answer:

6 0

So we're trying to solve for x. To do this we need to balance the equation.
-121 -4x = 39 + 6x
Get x on one side; add 4x to both sides.
-121 = 39 + 10x
Subtract 39 from both sides (remember when subtracting a negative to a negative, it's basically just adding with negative signs).
-160 = 10x
Divide both sides by 10.
x = -16.
Hope this helps!

What is the volume of the following cylinder?

tigry1 [53]

If the diameter is 12, then its radius is half that, or 6.

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=6\\
h=15
\end{cases}\implies V=\pi (6)^2(15)\implies V=540\pi$
