David cuts a 6 metre long pole into three different pieces,The largest piece is 40cm longer than the middle piece and the middle piece is 70 cm longer than the shortest piece. What is the size of the largest piece ?

Answer 1

Shortest piece : x
middle piece : x+70
longest piece: x+70 + 40 = x+110

x + x+70 + x+110 = 600

solve for x, then evaluate x + 110
