Answer:
1x
Step-by-step explanation:
2x-3x[x-1]
=2x-3x+1
=-x+1
=0
50+75= 125$
125 divided by 65 = 1.92
1.92 rounds up to 2, so it would take approximately 2 hours.
If you need to find an exact number then we need to find a number greater than 125 that both 50 and 65 can fit into.
125+ 50 + 50 + 50 + 50= 325
325 divided by 65= 5
So it would take 4 hours of work with Abe to cost 325 and 5 hours of work with the other service.
