For this case we have the following system of equations:

To solve, we add both equations:

We find the value of "x":

The solution is (-4,10)
ANswer:
Option C
Answer:
68
Step-by-step explanation:
79 - 11 is 68, so I think 68 is the answer.
The formula for the volume of a box (assuming that it is in the shape of a cube) is <u>V=B^3</u>.
12=B^3
Now, do the cube root of 12 to find each dimension, all dimensions will be equal as it is a cube.
B= about 2.29 (when doing on a calculator keep full answer and do not round)
Now to find the volume of box B, multiply each dimension by 5
5(2.29...) times 5(2.29...) times 5(2.29...)
=1,500 m^3
Hope this helps!
I think just divide 4 by 16 and that will be your answer? I'm not sure but the answer that I'm giving you is 4 your welcome if it helped in anyway
