9. A full-grown giraffe is about 6 times
heavier than a full-grown lion. A full-grown
cheetah is about one-quarter as heavy as a
full-grown lion. Together, they are about
450 kg. What is the approximate mass of each
animal?

Solution:

Let "a" be the mass of full grown giraffe

Let "b" be the mass of full grown lion

Let "c" be the mass of full grown cheetah

A full-grown giraffe is about 6 times  heavier than a full-grown lion

a = 6b ------- eqn 1

A full-grown  cheetah is about one-quarter as heavy as a  full-grown lion

Together, they are about  450 kg

Therefore,

a + b + c = 450

Substitute eqn 1 and eqn 2 in above

Substitute b = 62.07 in eqn 1

Substitute b = 62.07 in eqn 2

Thus, mass of full grown giraffe is 372.42 kg and mass of full grown lion is 62.07 kg and mass of full grown cheetah is 15.51 kg
