The copy machine makes 105 copies per minutes.
Step-by-step explanation:
Given,
Copies printed by photocopy machine = 735
Time taken by machine = 7 minutes
To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.
Copies printed in one minute = 
Copies printed in one minute = 105 copies

Answer:
3/4
Step-by-step explanation:
Let the unknown number be x.
Subtract 1/2 from the unknown number: x - 1/2
Multiply the result by 1/2: 1/2(x - 1/2)
You get 1/8: 1/2(x - 1/2) = 1/8
Now we solve the equation for x.
1/2(x - 1/2) = 1/8
Multiply both sides by 2.
2 * 1/2(x - 1/2) = 2 * 1/8
x - 1/2 = 1/4
Multiply both sides by 4
4x - 4 * 1/2 = 4 * 1/4
4x - 2 = 1
Add 2 to both sides.
4x = 3
Divide both sides by 4.
x = 3/4
