a 17in piece of steel is cut into 3 pieces so that the second piece is twice
as long as the first piece, and the third piece is 3in more than four times
the length of the first piece
:
Let x = length of the 1st piece
:
Write an equation for each phrase
:
"the second piece is twice as long as the first piece,"
2x = length of the 2nd piece
:
"the third piece is 3in more than four times the length of the first piece"
4x + 3 = length of the 3rd piece
:
Solve
x + 2x + (4x+3) = 17
7x = 17 - 3
7x = 14
x = 2 inches is the 1st piece.
I'll let you find the length of the other two pieces
