Answer:
x=
Step-by-step explanation:
Volume of a cylinder = the area of the base x height of the cylinder
Area of base =

r^2
A = 6^2(

)
A = 36

V = 36

x 12
V = 432

5 cylinders = 5V
5V = 5 x (432

)
5V = 2160

Final answer: Alex needs to buy 2160

or 6785.84 cubic feet worth of compressed air to fill all of the cylindrical tanks.

Answer:
answer b is correct answer
Step-by-step explanation:
solution ? you mean where both lines cross each other ?
these are 2 parallel lines (same slope, but different y-intercept), so they never cross each other.
there is no solution.
formally :
3x - 1 = 3x + 4
-1 = 4
this is wrong. therefore there is no solution.
