Guest Posted January 28, 2008 Report Share Posted January 28, 2008 This is an easy one. A 2x4 is cut into three pieces, The first piece is 3 inches longer then the third piece. The seconded piece is 2 inches shorter than the third piece. The three pieces together measure 1 inch over one yard. How long is each piece?

0 Guest Posted January 28, 2008 Report Share Posted January 28, 2008 Algebra says: Let x = 3rd piece. Therefore... x+3 = 1st piece, and x-2 = 2nd piece. So... x + x+3 + x-2 = 37 3x + 1 = 37 3x = 36 x = 12 x+3 = 15 x-2 = 10 So the length of the three pieces are 15, 10, and 12 inches. Quote Link to comment Share on other sites More sharing options...

Omg why don't just state a number in stead of saying "1 inch over one yard" , inches / yards / feet don't make sence to everyone. The puzzle is easy, I just don't know what number to use for "1 inch over 1 yard". [b]Spoiler[/b] for [i]solution[/i]: x + x + 3 + x - 2 = y 3x + 1 = y piece 3 = x = (y-1)/3 piece 1 = x + 3 = ((y-1)/3)+3 piece 2 = x - 2 = ((y-1)/3)-2 Quote Link to comment Share on other sites More sharing options...
0 Guest Posted January 28, 2008 Report Share Posted January 28, 2008 Hmm i can't even edit my own reply, strange. So here is my addition to my previous post. edit: What i want to say is: '1 inch over a yard' isn't really working as a number, also i could transform this to a distance in lightyears if I wanted to. You didn't say how you want your answer, metrics system, feet / inches. I guess that makes it safe to use Y in stead of a number. Quote Link to comment Share on other sites More sharing options...
