Comparing the diagram, we know the length of 1 super-high jump is 1 foot cause both times, he covered the same distance, so the difference of 3 super-high jumps and 2 super-high jumps is 6-5= 1 ft
and his whole super-high jump routine is 3+5= 2+6= 8 ft

Answer:

a. x = 1 foot; b. whole routine = 8 feet

Step-by-step explanation:

a.

3x + 5 = 2x + 6

Combine like terms:

3x - 2x = 6 - 5

1x = 1

1x/1 = 1/1

x = 1

b.

Use either attemp and add (I used the first attempt):

3(1) + 5 = ?

3 + 5 = 8

Entire routine = 8
