Step-by-step explanation:
The given system is:
4x-3y=8
5x-2y=-11
We make x the subject in the top equation to get:

Plug this expression for x in the bottom equation to get

We expand to obtain

Answer:
Step-by-step explanation:
We know that the volume of a cone is given by the following relation:
V = (pi * r^2 * h)/3
where r is radius and h is height of the cone
In our case, radius is diameter divide by 2:
V = (pi * (8/2)^2 * 10) / 3 = 167.55 cubic inches
So the container holds 167.55 cubic inches
Answer:
well, a supplementary angle is two angles that sum up to 180 degrees. If one angle is 8, then the other angle would be found by using 180-8=? Or ?+8=180. Because of this, the other angle would equal 172
