Answer:
x = 2 y
190 = 10 y + 18 x :
where, x = Number of large boxes, y = number of small boxes
Step-by-step explanation:
Let us assume the number of large boxes shipped = x
So, the number of small boxes shipped = y
⇒ x = 2(times y) = 2 y, or x = 2 y
Now, the volume of 1 small box = 10 cubic feet
So, the volume of y small boxes = y ( Volume of 1 small box)
= y ( 10) = 10 y
Now, the volume of 1 large box = 18 cubic feet
So, the volume of x large boxes = x ( Volume of 1 large box)
= x( 18) = 18 x
Total Volume Transferred = Volume of {Small boxes + Large boxes}
or, 190 cubic feet = 10 y + 18 x
So, the needed system of equations is:
x = 2 y
190 = 10 y + 18 x :
where, x = Number of large boxes, y = number of small boxes
