A bird has a head 9 cm long. The tail is equal to the size of the head plus a half of the size of the body. The body is the size of the head plus the tail. How long is the bird?
head = 9cm tail = 9 + 0.5*(9+tail) tail = 9 + 4.5 + (tail/2) (tail/2) = 13.5 tail = 27 Total bird length = tail + body + head = 27 + (9 + 27) + 9 = 72cm
head=9 tail=9+body/2 body=head+tail body=9+(9+body/2) body=18+18+body/2 2body=36+body body=36 tail=9+36/2 tail=24 the bird size is =(head+tail+body)=(9+24+36)=69cm
