Use an algebraic expression to represent each sequence of lengths shown below.  

  1. A line segment with 3 sections, and labeled as follows: x, 1, and x.

    Think of this as being a tightrope for Croakie to cross. How would you describe his path using this picture?

  1. A line segment with 4 sections. 3 equal sections are each labeled, m, with last section labeled 5.

    This problem is very similar to part (a).
    If the lengths labeled '''' were instead labeled as '''', how would you write the expression?

  1. A line segment with 4 sections, labeled as follows: y, 2, y, and 2.

    Use parts (a) and (b) as guides if you are having trouble. Remember that the variable represents a number, so you can use it in an expression just as you would a number.
