Question 38885: One machine in a print shop can produce a certain number of pages twice as fast as another machine. Operating together, these machines can produce this number of pages in 8 minutes. How long would it take each machine, working alone to produce this number of pages.

You can put this solution on YOUR website!
One machine can produce 2x as fast as other
Other can produce x as fast.
Equation:
1%2F2x%2B1%2Fx=1%2F8
%28%282x%29%2B%28x%29%29=%28%28x%29%282x%29%29%2F8
3x=2x%5E2%2F8
24x=2x%5E2
x%5E2-12x=0
x(x-12)
x=12
2(12)=24
Hence, one can produce the number of pages is 12 minutes while the other can produce the number of pages in 24 minutes.
