Yosemite Falls, the highest waterfall in the United States, is actually made up of three smaller falls. The Lower Yosemite Falls is feet shorter than the Middle Cascades Falls. The Upper Yosemite Falls is feet more than twice the Middle Cascades Falls. If the entire set of waterfalls is feet long, how tall is each of the smaller waterfalls?

Write an expression for the height of each falls.






Now note that the sum of these expressions is feet.

Solve for .

Remember that .
Use the value you found for to calculate the height of the lower and upper falls.
