and the cat’s mass is 4 times as much as a kitten’s, what is the mass of each kitten?

Answer 1

kitten --- x kg
cat ------4x kg

4(x) + 4x = 10

take over

Answer 2

But how will I get cat is 5kg and kittens are 1.5kg each

Answer 3

Where did you get a kitten to weigh 1.5 kg ??

4x+4x= 10
8x=10
x = 1.25 kg

so each kitten weighs 1.25 kg
and the cat weighs 4x or 4(1.25) = 5 kg

check:
does the cat weigh 4 times as much as a kitten
what is 4(1.25) ?
= 5, check!

what is the total weight of the 4 kitten and the cat
what is 4(1.25) + 5 ?
= 10 check !

My answer is correct

Answer 4

I agree ... Thanks
