8/10 = 80/100
So the sum is 80/100 + 8/100 = 88/100 or 22/25
The slope of the ramp would be 5/9
Answer:
100% of the pizzas have 12 slices or 8 slices
(20x.45x8) + (20x.55x12) = total slices
First we know that:
AB+BC=AC
now , since B is the midpoint of AC, this means that AB=BC
therefore,
AB+BC=AC can also be written as
AB+AB=AC
3x-1+3x-1=8x-20
6x-2=8x-20
-2+20=8x-6x
18=2x
x=9
therefore:
AB=3(9)-1=27-1=26
AC=8(9)-20=52
BC=AB=26
