For the first one...
1,15
2,30
3,20
and for the second one is the same as the first one.
EXTRA CREDIT:
Week one increases by 15, week two increases by 15 but week three decreases by 15. The total miles ran would be 15 miles
15+15=30 30-15=15 miles
So a decrease of 16% followed by an increase of 14% is the same as multiplying by 0.9576 (which is a decrease of 4.24%)
Split 33 into two numbers that when added up are 33.
So 12 to 21, which when divided by 3, are 4 to 7.
Answer:

Step-by-step explanation:
<u>Given the following data;</u>
Length = 312 meters
Breadth = 186 meters
To find the perimeter of the rectangle;
Mathematically, the perimeter of a rectangle is given by the formula;
Perimeter = 2(L + W)
Perimeter = 2(312 + 186)
Perimeter = 2(498)
Perimeter = 996 meters
To the nearest meters, we have;
Perimeter = 996 ≈ 1000 meters
Let P represent the perimeter of a rectangular field.
900 < P > 1000
Therefore, 
If you can read the chicken scratch there is your answer. Hope this helps!
