We kinda need a picture to solve your question.
First, find a common denominator.
2 and 1/3 = 2 and 3/9.
4 and 2/9 - 2 and 3/9 = 1 and 8/9. Hope it helps!
Answer: x=-9/2
Alternative Form: x= -4 1/2, x= -4.5
Answer: 15.707 feet of fence.
Explanation: The formula to find this would be the one you’d use to find circumference, which is: C = 2(Pi)r
Half of the diameter is the radius, so plug that in and it becomes:
C = 2(pi)2.5
Then you just solve it and the result is C = 15.707
