Given
See attachment for chart
Required
Number of off days
To do this, we simply calculate the expected value of the chart.
This is calculated as:

Where
x = days
f = chances
So, we have:



First you need to get x on one side of the equation and to do that subtract 2a from both sides.
28 + 2a = 5a + 7
-2a -2a
28=3a+7
Then we need to get a alone by subtracting 7 on both sides.
28=3a+7
-7 -7
21=3a
Finally divide each side by 3 and you should get a = 7. Hope this helps!

Step-by-step explanation:
Edge
the formula for the perimeter of a rectangle is
P= 2(L+W)
with L representing length and W representing width
since we have the perimeter and the length, we can plug the values into the equation to find W
346 = 2(92+w)
346 = 184 + 2W
162 = 2W
81 = W
the width of the field is 81 yards.
hope this helped!
