<span>A. When adding two rational numbers a/b and c/d, the numerators a and c do not have to be integers. Therefore, the sum does not have to be a rational number. I think this is right might nor be :/

Answer:
V=8250-18*c
Step-by-step explanation:
The equation will be:
Where:
- V is the volume of corn in the silo after loading begins.
- 8250 is the initial volumen on the silo before the loading begins.
- 18 is the 18 cubic feet per hour given as rate of loading.
- c is the number of hour elapsed after loading begins.
To find the volume, V, of the corn in the silo c hours after loading begins, we substract from the initial volume the quantity of corn loaded and this is 18*c, that is the number of hour elapsed multiplyed by the rate of loading.

Answer:
V = (improper fraction) 3/2 or (mixed number) 1 1/2
Step-by-step explanation:
3/2-7/4 V =-9/8
First, let's isolate -7/4 V by subtracting 3/2 on both sides of the equal sign. We'll end up with this:
-7/4 V = -9/8 - 3/2
Now, we have to make -3/2 have the same denominator as -9/8 and -3/4 = -12/8 so we'll write that down:
-7/4 V = -9/8 - 12/8
Simplify:
-7/4 V = -21/8
We're going to isolate V by dividing both sides by -7/4:
(-7/4 V)/(-7/4) = (-21/8)/(-7/4)
Multiplying -21/8 and -(4/7) is the same thing as dividing -21/8 by -7/4:
V = -21/8 * -4/7
V = 3/2
or
V = 1 1/2
Hope this helps! :)
