Question

The body of a fish is 4 times the length of

its head. Its tail is 2 cm longer than the head.
The total length of the fish is 20 cm. How
long are the head, body, and tail of the fish?

Answer 1

Head=3cm

Body=12cm

Tail=5cm

Explanation:

H= head

B=body

T=tail

B =4h

T=2+h

Total length= 20cm

20cm = b+t+h

20cm= 4h+(2+h)+h

20cm= 6h+2

18cm=6h

3cm=h

Body 4(3)=12

Tail= 2+3= 5
