Step-by-step explanation:
a=7/32
The answer for number 7 is 10
Step-by-step explanation:
students in previous year=35
students in next year=42
difference=42-35
=7
Now,
change%=7/42×100%
=16.67%
Roy: y=150-1.5x
Luis: y=200-2.5x
150-1.5x=200-2.5x
150=200-x
-50=-x
50=x
So in 50 weeks, Roy and Luis will weigh the same at 75 pounds each.
