Question

Three pieces of pipe are needed for a plumbing repair. The plumber brought one 50 cm pipe for the job. The middle-sized piece is 12 centimeters shorter than the longest. The shortest piece is 8 centimeters shorter than half the longest piece. How long are the pieces of pipe?

Answer 1

L represents the longest

L - 12 represents the middle

L/2 - 8 represents the shortest

 

L + L - 12 + l/2 - 8 = 50

 

Can you solve for L and answer?
