i need help, please tell me how to set this up and solve

answers:
Suzanne say: hint:
one piece = x
other piece is 2x
sum of 2 pieces = 48
-
Deborah say: let the length of the smaller piece be x... then the length of the bigger piece is 2x...
2x + 1x =3x
3x =48 inches
1x = 16... 2x = 32
the smaller piece is 16 inches long and the bigger one is 24 inches long...

Ann say: hint:
one piece = x
other piece is 2x
sum of 2 pieces = 48

MICHAEL K say: 16 inches and 32 inches.

peevee say: Let the length of the smaller piece be x. then the length of the bigger piece is 2x.
2x + 1x =3x
3x =48 inches
1x = 16. 2x = 32
The smaller piece is 16 inches long and the bigger one is 24 inches long.

Sqdancefan say: Fold the rope into thirds and cut at one of the folds. The short piece will be 16 inches; the remaining longer piece will be 32 inches.

Como say: x + 2x = 48
3x = 48
x = 16
Pieces are 16 ins and 32 ins

DEBS say: You have two variables which, when added, equals 48. Use x as the longer piece and y as the shorter)
Thus, 2x + y = 48.
Then solve.

megalomaniac say: Let X and Y represent the two pieces of rope.
The two pieces of rope add up to 48 inches: X + Y = 48
One piece is twice as long as the other: X = 2Y
Combine the two equations: (2Y) + Y = 48
Solve for Y: 3Y = 48, Y = 16
Solve for X: X = 2Y, X = 32

Chris P say: One piece is 16 inches long.
The other is 32 inches long.
You don't need to "solve it" you just need to know the two and three times-tables.
-
Valerie say: x=short piece, 2x=long piece...
x+2x=48, 3x=48, x=16, 2x=32, 16 inches & 32 inches
-
!!! say: x=short piece, 2x=long piece.
x+2x=48, 3x=48, x=16, 2x=32, 16 inches & 32 inches

alex say: hint:
One piece = x
other piece is 2x
sum of 2 pieces = 48
