Answer:
First number is 6
Second number is 2
Step-by-step explanation:
The trick is that we need to set up two equations. Nor simplicity's sake I'm going to say the first number is x and the second number is y.
First we know that the first number (x) is 4 less than the second number (y).
Less means subtraction.
x-4=y
Then we know that 4 times x is 14 more than 5 times the second. More is addition and times is multiplication.
4x=14+5y
Now we use substitution to find out what x (the first number) is, subbing x-4 in for y.
4x=14+5(x-4)
4x=14+5x-20
-x=-6
x=6
First number is 6
Lastly, we sub 6 back into one of the equations. It's easier to us the first equation.
x-4=y
6-4=y
2=y
The second number is 2

Answer:
Step-by-step explanation:
A) The equation for the volume of a sphere is 
As the diameter of each ball is 3 inches, that would mean that the radius of each is 1.5 inches.
Now we can plug our value into the equation

This would simplify to
V = 14.12716694
B) The equation for the volume of a cylinder is 
As there are 3 balls in a container and the diameter of each is 3, that would mean that the height is 9 inches
Now we can plug in our values into the equation

This would mean that this equation would simplify to
27\pi 
C) To find the empty space, we must take the total volume, the volume of the cylinder, and subtract the volume of the tennis balls
This would mean that the equation would look like this

This would simplify to
42.41150082
of empty space.
