Answer:

C. $5x=25$

Step-by-step explanation:

Given:

$2x-3y=-1\\3x-3y=26$

Add the two equations, we get

$2x-3y+3x+3y=-1+26\\(2x+3x)+(-3y+3y)=25\\5x+0=25\\5x=25$

Therefore, the correct option is option C.

What number must be added to 14,056 to result in the sum of 38,773

Vlada [557]

24,717.
What you have to do is subtract 38,773-14,056 and then the answer would be 24,717. So all together 24,717 must be added to result in the sum of 38,773.
14,056+24,717=38,773.

A pile of sand in the shape of a cone has a diameter of 8 in. and a height of 5 in.

max2010maxim [7]

if it has a diameter of 8, that means its radius is half that, or 4.

$\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}~~
\begin{cases}
r=radius\\
h=height\\[-0.5em]
\hrulefill\\
r=4\\
h=5
\end{cases}\implies V=\cfrac{\pi (4)^2(5)}{3}\implies V=\cfrac{80\pi }{3}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
~\hfill \stackrel{using~\pi =3.14}{V= 83.7\overline{3}}~\hfill$
