The entire race is 1 full race.
One full race is 1.
He ran 3/8 of 1, so he ran 3/8.
He needs to run the rest of the race.
The rest is unknown, so we call it x.
When you add 3/8 to the unknown, you get the full race.
The equation is
x + 3/8 = 1
Change 1 to a denominator of 8.
x + 3/8 = 8/8
Subtract 3/8 from both sides.
x = 5/8
Answer: He still needs to run 5/8 of the race.

5x = 15
x = 3
3(3) - 5y = -16
9 - 5y = -16
5y = -16 - 9
5y = - 25
y = - 5
(3, -5)
Answer: 21 shifts
Explanation:
If you want to have nurses on duty 24 hours a day 8 hours at a time, first divide 24 by 8. You get 3, which is the amount of shifts per day. Then multiply 3 by the amount of days in a week, 7, and get 21 shifts per week. Hope this helps!
