Question

When loaded with bricks a pickup truck has a mass of 11.600 kg if the mass of the truck is three times the mass of the the bricks find the mass of the brick

Answer 1

Answer:

8700KG

Step-by-step explanation:

You are asked to find the mass of bricks so that is your unknown.

Let X = the mass of bricks.

The mass of bricks and the load = 11600.

So the empty lorry (the British word for a truck) is 11600 - X.

If the bricks weighed 100 kg, then the truck would weigh 11500, right?

The bricks weigh 3 times as much as the empty truck.

So 3 times the weight of the truck equals the weight of the bricks.

3(11600-X) = X

X = 34800-3X

4X = 34800

X = 34800 / 4

X = 8700
