A triangle has sides with lengths of 60 yards, 63 yards, and 87 yards. Is it a right triangle?
Yes or No

Answers:

Explanation:

The first blank represents the distance that corresponds to t = 1 hour.

We'll replace t with 1 to get...

d = 54t

d = 54*1

d = 54

Therefore, 54 goes in the first blank. It means that Isaac traveled 54 miles after 1 hour.

We repeat these steps for t = 3

d = 54*t

d = 54*3

d = 162

This means he traveled 162 miles after 3 hours

So 162 goes in the second blank

Side note: your teacher wrote 180 but s/he should have written 108 instead because 54*2 = 108
