pls solve this with working the best one will be marked as brainliest​

Answer 1

Answer:

let the mass of empty lorry be = X

then, the mass of the bricks = 3X

According to question

X + 3X = 11600

4X = 11600

X = 11600/4

X = 2900

so, the mass of the bricks = 3X

= 3×2900

= 8700kg

Answer 2

Mass of the bricks is 8700 kg

Step-by-step explanation:

GIVEN

Mass of loaded bricks lorry = 11600 kg

Mass of Loaded lorry = 3 × Mass of empty lorry

___________________________

TO FIND

Mass of the bricks

___________________________

Let's take the mass of empty lorry = x

The mass of loaded lorry = 3x

We know that,

Mass of loaded bricks lorry = 11600 kg

x + 3x = 11600 kg

4x = 11600 kg

x = 11600 / 4

x = 2900

x = kg

Mass of the empty lorry is 2900 kg

___________________________

We know that,

Mass if the bricks is 3 times the mass of empty lorry

Mass of Bricks = 3x

Mass of Bricks = 3 × 2900

Mass of Bricks = 8700

Mass of Bricks = 8700 kg

Mass of the bricks is 8700 kg
