A 140-meter rope is cut into four segments. The first segment is twice as long as the second. The third segment is three times as long as the second, and the fourth segment is four times as long as the second. Find the length of each segment. Write an equation that represents this situation and solve it. Be sure to define your variable. 

Answer

4) a  = first segment , b = second , c = third , d = fourth , 

  a + b + c + d = 140 , a = 2b , c = 3b , d = 4b , 2b + b + 3b + 4b = 140 , b = 14m , 

   a = 28m , c = 42m , d = 56m
