Answer:
6/1
Step-by-step explanation:
Since eleven is odd, there must be a centra element, which in this case is the sixth. So, we can write 11 consecutive integers as

Since the arithmetic mean is the sum of the values, divided by how many they are, we have

So, the mean of 11 consecutive integers is the 6th integer.
(22 ft)*(12 in/ft)/(22 in) = 12 . . . . plants per side
12*4 = 48 plants are needed for the outside border.
In this right triangle we have the opposite and adj which is tangent
tan 37=9/x
since we have the x in the bottom so we switch it with tan37
which is
x=9/tan 37
x=11.94340339
x=11.94
Collect the like terms
3x+13x=16x
16x+8y
