Question

The mass of a basket containing 3 balls was 3.64 kilograms. The mass of the same basket and 5 balls is 5.26 kilograms. Find the mass of the empty basket in kilograms.

Answer 1

Step-by-step explanation:

Let X is mass of basket

and Y is mass of balls

so 1st equation is

X+3y= 3.64

and

2nd equation is

X+5y=5.26

so we will subtract equation 1st from 2nd

(x+5y)-(x+3y) = 5.26 - 3.64

and we will get

2y = 1.62

It means mass of 2balls = 1.62

and

mass of 1 ball = 1.62/2 = .81

mass of 3 balls: .81 × 3 = 2.43

mass of 5 balls: .81 × 5 = 4.05

mass of empty basket = 3.64 - 2.43 = 1.21

mass of empty basket = 5.26 - 4.05= 1.21

Hope its clear

All the best
