Well 22/7 is 3.14 and so on but since there is a little more than 3 you need to make sure he covers up all the fencing places... SO John will need 4 fences
For the given systems A and B:
1) Replace the first equation of A by the sum between the two equations of A.
2) Yes, the systems are equivalent.
<h3>
How to get system B from system A?</h3>
Here we have the two systems of equations:
A:
6x - 5y = 1
-2x + 2y = -1
B:
4x - 3y = 0
-2x + 2y = -1
The second equation is the same in both systems, so we only look at the first equations.
In A we have:
6x - 5y = 1
If we add the second equation of A, then we get:
(6x - 5y) + (-2x + 2y) = 1 + (-1)
4x - 3y = 0
This is the first equation of B.
Then we need to replace the first equation by the sum between the first and second equations.
2) Are the systems equivalent?
Yes, because we did not "modify" system A, we just rewrite it and we got system B, then both systems have the same solutions.

The answer is B
The correct inverse of 3x+1 is actually (1/3)x - 1/3
plug in 10 to the inverse
10/3 - 1/3 = 9/3 or 3
this gives you the point (10,3)
The probability is 50% or 1/2 since the amount of even numbers and odd numbers is equal after 3 is out of the equation.
