(Show your working out in steps)

Answer 1

80 kg.

Explanation:

Let's denote the mass of one sheep as "x" (in kg). According to the given information:

1. Eight sheep have the same mass as three sheep and a cow.

2. The mass of the cow is 400 kg.

Step 1: Express the given information in equations:

- 8x = 3x + 400

Step 2: Solve for "x" (mass of one sheep):

Subtract 3x from both sides to isolate the "x" term:

- 8x - 3x = 400

- 5x = 400

Step 3: Divide both sides by 5 to find the value of "x":

- x = 400 / 5

- x = 80

So, the mass of one sheep is 80 kg.
