The point of interest is where the graphs cross.
(x, y) = (11, 5)

Linear equations can be solved by any of a variety of methods. Using substitution for y, you have
.. 7x +3(27 -2x) = 92
.. x = 11 . . . . . . . . . . . . . collect terms, subtract 81
Then
.. y = 27 -2*11 = 5
Using subtraction, you would take 3,000 and subtract 1968 from it to leave you 1,032. With that number, the answer to your question is "C"
You haven't shared all of the question, so I'll guess that you want to find "how fast is the area of the sphere increasing?"
Area of a sphere = 4*pi*r^2
Rate of change of area of a sphere with respect to radius r:
dA/dr = 8*pi*r*(dr/dt)
Here, that would come out to
dA/dr = 8*pi*r*(2 inches / sec)
If you meant, "how fast is the volume of the sphere increasing?" you'd need to use a different equation:
V = (4/3)*pi)*r^3
and go through a similar process.

isolating a:
(a + b + c)/3 = z
(a + b + c) = 3z
<h2>a = 3z - b - c</h2>
