Abasket with 25 similar ball has a mass of 10.3kg. the same basket with 10 similar balls has a mass of 4.45 kg. what is the mass of the box? give your answer in grams

550g

Step-by-step explanation:

mass of ball in kg=y

mass of basket in kg=x

25y+x=10.3 ->(01)

10y+x=4.45 ->(02)

(01)-(02)

25y+x-10y-x=10.3-4.45

15y=5.85

y=0.39

substitute  y=0.39 in (02)

10(0.39)+x=4.45

3.9+x=4.45

x=4.45-3.9

x=0.55

Therefore mass of basket is 550g.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
