  C.  all real numbers except 3/4

Step-by-step explanation:

f(x) and g(x) are both defined for all real numbers. However, the ratio f/g will be undefined where g(x) = 0. That occurs when ...

  4x -3 = 0

  4x = 3 . . . . . add 3

  x = 3/4 . . . . . divide by 4

The value of x = 3/4 makes f/g undefined, so must be excluded from the domain.

To determine how many there are in total/separate, we need to know how many pounds are in 1 ton.

1 ton = 2,000 pounds.

Since we have 3, 5 and 7 tons, let's convert them.

3(2,000) = 6,000
5(2,000) = 10,000
7(2,000) = 14,000

We have either 6,000 / 10,000 / 14,000 pounds as translations, or you maybe want the sum.

To find the sum, we add all the numbers together.
6,000 + 10,000 = 16,000
16,000 + 14,000 = 30,000

Your answer is 30,000 pounds.

I hope this helps!
