You can put this solution on YOUR website! 1st piece is X feet long, second is 3X and third is 6X
Total is 10X, so X=18
So first piece of board is 18 foot long (the others are 54 and 108 foot long)
You can put this solution on YOUR website! A 180 ft long board is cut into 3 pieces. The second piece of board is twice as long as the first. The third piece of board is six times as long as the first.
What is the length of the first piece of the board?
let one board be x
the second board will be 2x
the third will be 6x
the sum of all these is 180 feet
x+2x+6x = 180
9x = 180
x= 20 feet the first board
