A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The
lina2011 [118]

Answer:

x is the number of large boxes shipped

y is the number of small boxes shipped

7 large boxes were shipped

14 small boxes were shipped

Step-by-step explanation:

The volume of each small box is 6 cubic feet and the volume of each large box is 12 cubic feet.

There were twice as many small boxes shipped as large boxes shipped : so if x large boxes , and y small boxes were shipped, then ,y =  2x small boxes were also shipped.

the total volume of all boxes was 168 cubic feet, which means:

y = 2x ...................(1)

6y + 12x = 168 .......(2),

then, replace y to 2x in the second equation

6(2x) + 12(x) = 168,

12x + 12x = 168,

24x = 168,

x = \frac{168}{24} = 7,

since the small boxes = 2x,

2(7) = 14 boxes, so there are 14 small boxes being shipped,

and x = 7, so there are 7 large boxes being shipped, since x is the number of large boxes being shipped.
