Hope this helps

Answer 2

1.21 kilograms

Explanation:

Let y represent the mass of the empty basket, and x represent the mass of each ball

Create a system of equations:

3x + y = 3.64

5x + y = 5.26

Solve by elimination by multiplying the top equation by -1

-3x - y = -3.64

5x + y = 5.26

Add them together, then solve for x:

2x = 1.62

x = 0.81

Plug this back into one of the equations and solve for y:

3x + y = 3.64

3(0.81) + y = 3.64

2.43 + y = 3.64

y = 1.21

So, the mass of the empty basket is 1.21 kilograms
