Polygon Diagonals. The number of diagonals in a polygon = n(n-3)/2, where n is the number of polygon sides. For a convex n-sided polygon, there are n vertices, and from each vertex you can draw n-3 diagonals, so the total number of diagonals that can be drawn is n(n-3).
This is super simple. Begin with cross multiplying
35/x=7/13 becomes (35)*(13)=(7) *(x)
Then multiply my love muffin, you get...
455=7x
divide both sides by 7
65=x
-or-
x=65
hope that helped :)
They are equal because if you divide 4÷1.0 your answer would be 0.4
The first one is $4 per bag, as given
For the he second one, you divide $15 by 4, you got $3,75 per bag
Therefore, the second one has the better unit price
