Each of the diagrams below represents a sequence for an acrobat on a tightrope. Each letter represents the unknown length of a trick. For each part below, figure out how far the acrobat travels during each trick (that is, the length represented by each letter). Show how you know.
is the same as , can you think of a way to find the value of ?
To find the value of both
's combined, we can subtract from .
Now you know that two
's are equal to . Can you find the value of one ?
Do you think you can use a similar strategy as in part (a)? Remember, try to find the value of just one j.
is the same as . Can you find the value of ? . Remember to show how you know!
is the same as . This simplification should make finding easier.
's equal , how much is one ?
