Hi there! The answer is A.

5x + 48 + 7x = 12(x + 4)
Work out parenthesis.

5x + 48 + 7x = 12x + 48
Collect terms

12x + 48 = 12x + 48
Now we can see that both sides of the equation are exactly the same. Therefore, it doesn't matter whatever value of x you plug into the equation. Each value of x you plug into the equation makes the equation correct, because both sides are the same (both sides have the same outcome value).

The answer is A.

A manufacturing company ships its product in two different sizes of truck trailers. Each shipment is made in a trailer with dime
kherson [118]

Answer:

Mean volume shipped per trailer load = 2960 ft³

Step-by-step explanation:

Since both trailers are always full,

Total volume in one 30 feet trailer shipment = 8 × 10 × 30 = 2400 ft³

Total volume in one 40 feet trailer shipment = 8 × 10 × 40 = 3200 ft³

Assuming a basis of 10 shipments, 3 shipments are done using the 2400 ft³ trailer and 7 shipments are done using the 3200 ft³ trailer.

Mean volume shipped per trailer load = total volume shipped/number of shipments

Total volume shipped = (3 × 2400) + (7 × 3200) = 7200 + 22400 = 29600 ft³

Number of shipment in the basis used = 10

Mean volume shipped per trailer load = 29600/10 = 2960 ft³
