A fish caught whose tail weighed 9 pounds. His head weighd as much as his tail and half of his body, and his body weighed as much as his tail and head. How much did the fish weigh.?
Is 40 1/2 lbs right or wrong?
w = t + b + h
t = 9
h = t + b/2 ... h - 9 = b/2 ... 2 h - 18 = b
b = t + h ... b = h + 9
2 h - 18 = h + 9 ...solve for h , then substitute back to find b
