    This is similar to writing an expression for an acrobat's routine. Think of the tricks as being numerical lengths of the rope.

    First, describe the routine based on the diagram.

    The acrobat performs a trick three times and then walks feet to get to the end of the foot tight rope.

    Next, determine how far each trick travels. Looking at the tightropes, the 's match up with feet. Since unknown, but equal, lengths combine to make feet, you know that each length is feet.

    The trick travels feet.
