Question

5. A fish had a tail as long as its head plus a quarter the length of its body. Its body was three-quarters of its total length. Its head was 9 inches long. What was the length of the fish?

Answer 1

Answer:

288"

Explanation:

L tail= L head + L body/4

= 9" + L body/4

Total L= L tail + 9" + L body

=(9"+ L body/4) + 9" + L body

=18"+(5/4)*L *3/4

so

L - L*5/4*3*4 =18"

L*(1-15/16)=18

L*1/16=18

L=18*16

=288"
