Question

When loaded with bricks, a lorry has a mass of
11 600 kg. If the mass of the bricks is three times that
of the empty lorry, find the
mass of the bricks.
​

Answer 1

Answer:

8,700kg

Step-by-step explanation:

mass of empty lorry = L

Total mass after loaded with bricks = Mass of empty lorry + mass of the bricks

11,600kg = L + 3L

4L = 11,600kg

L = 2,900kg

Mass of the bricks = 3 x 2,900kg = 8,700kg
