Now Croakie can do a super high jump! Homework Help ✎

The first time he performed his new super-high-jump routine, he did three super-high jumps and then hopped five feet. The second time, he did only two super-high jumps and then hopped six feet. Both times, he covered the same distance. His attempts are shown in the diagram below.

How far does Croakie travel in one super-high jump? Explain or show how you know.

In Croakie's first attempt he crossed the tightrope like this:

*x*+*x*+*x*+ 5 = length of the tightropeIn Croakie's second attempt he crossed the tightrope like this:

*x*+*x*+ 6 = length of the tightropeBecause both equations are equal to the length of a tightrope, you can make them equal to each other,

like this:*x*+*x*+*x*+ 5 =*x*+*x*+ 61 foot. Make sure you know how to get this answer.

How long is his whole super-high-jump routine? How can you tell?

Since you figured out that Croakie's super-high jump (

*x*) equals 1 foot, you can simply substitute

1 for*x*into either of his routines.
