Answer:
Im not sure about it.
Step-by-step explanation:
First make the y on a side alone without anything by multiplying both sides by 2 then dividing by three, then substitute the x by the x value of x represented in the ordered pairs, and if the the result was the same value for y as represented in the ordered pair, then the ordered pair is correct.
Given:
8 tasks
5/6 hours total
Unit rate per task:
5/6 hours ÷ 8 tasks = 5/6 * 1/8 = 5/48 or 0.10 hours per task
0.10 hours x 60 minutes/hour = 6 minutes per task.
Unit rate per hour:
8 tasks ÷ 5/6 hours = 8 * 6/5 = 48/5 = 9.60 tasks per hour or rounded to 10 tasks per hour.
Answer:

Answer:
2 7/5 or 2.5 times per day
Step-by-step explanation:
Given Deonadre runs 17 1/2 times around the reservoir in one week .
The rate per day will be the times ran in one week divided by 7 since there are seven days in one week .
Therefore
17 1/2
First change it to an improper fraction . We have
35/2
Now
35/2 /7
35/2 x 1/7
Multiply through
35/14
2 7/5 or 2.5 times
Therefore , Deonadre runs
2 7/5 times per day
