Adelivery truck is transporting boxes of two sizes: large and small. the combined weight of a large box and a small box is 90 pounds. the truck is transporting 70 large boxes and 65 small boxes. if the truck is carrying a total of 6150 pounds in boxes, how much does each type of box weigh?

A small box weighs 30 lb; a large box weight 60 lb.

Step-by-step explanation:

Let L = weight of large box

Let S = weight of small box

"The combined weight of a large box and a small box is 90 pounds."

L + S = 90

"The truck is transporting 70 large boxes and 65 small boxes. If the truck is carrying a total of 6150 pounds in boxes"

L = 90 - S    Equation 1

The truck carries 65 small boxes and 65 large boxes and another 5 large boxes.

65(90) + 5(90 - S) = 6150   Equation 2

We use these two equations (Eq. 1 and Eq. 2) as a system of equations.

L = 90 - S

5850 + 450 - 5S = 6150

6300 - 5S = 6150

-5S = -150

S = 30

L = 90 - S = 90 - 30 = 60

S = 30; L = 60

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
