Answer:
1 - 4y
Step-by-step explanation:
0.5 - Y - 5 -0.5x = y - 5
0.5 +5 -5 -0.5x = 2y
0.5 -2y = 0.5x
x = 0.5 - 2y /0.5
= 1 - 4y
A mixed number is a combination of a whole number and a fraction. The fraction 9/2 is equal to 4.5. So you would have to find a mixed number in between 4.5 and 5. You could do this by turning 5 into a mixed number, which would be 10/2.
So now you have to find a mixed number in between 9/2 and 10/2. The best way to do this is multiply both numbers so that you can get a wider range of numbers. You would not be changing the end result, you would only be changing the size of the fraction.
I would multiply both mixed numbers by 2, which would get you 18/4 and 20/4. That would mean that a number in between these two mixed numbers is 19/4. (which would simplify to 4.75)

Answer:
1135.2 in³
Step-by-step explanation:
The volume of a sphere is given by the formula ...
V = (4/3)πr^3
The difference in volume will be ...
∆V = Vb -Vs = (4/3)π(10^3 -9^3) = (4/3)π(1000 -729) = 4/3π·271 . . . cubic in
∆V ≈ 1135.2 . . . cubic inches
The basketball has a volume that is 1135.2 cubic inches greater.
