Vertices are formed when 2 sides come together on a polygon. So they are basically corners. The smallest amount of sides a polygon has is 3, which would be a triangle. And triangles have 3 corners, because with a triangle, each side touches the other two. So the minimum number of vertices needed to form a polygon would be 3.

Answer
5
Step-by-step explanation:
there are already 2 units in height therefore 2 plus 3 is 5
km + 5x = 6y
Subtract 5x from each side:
km = 6y - 5x
Divide both sides by k:
m = 6y - 5x / k
I believe it is $7.25.
This being because if you start with $21.75 you have to divide that by 3, because you have 3 people splitting the bill.
Another way to do this is by dividing .75 by three (which we know 75 divided by 3 equals 25 so the .75 divided by 3 equals .25. Then we know 21 divided by 3 is 7. So then you would just add 7 + .25 together and get $7.25!
I hope this helped!
