Respuesta :
The total weight of 1 load of bricks and 3 loads of sticks is. 385. 5 kilograms
let
the weight of a load of bricks = x
the weight of load of stick = y
A load of bricks is twice as heavy as a load of sticks. Therefore,
- 2y = x
The total weight of 4 loads of bricks and 4 loads of sticks is 771 kilograms. Therefore,
- 4x + 4y = 771
- 4(2y) + 4y = 771
- 12y = 771
- y = 771 / 12 = 64.25
The total weight of 1 load of bricks and 3 loads of sticks can be calculated below
- x + 3y
- 2y + 3y = 6y
- 6(64.25) = 385.5
Therefore, total weight of 1 load of bricks and 3 loads of sticks is. 385. 5 kilograms
