Sam is making Apple Pies and Pumpkin Pies for her Pie shop. She sells each Apple Pie for $6 and each Pumpkin Pie for $7. If Sam sells a total of 80 pies one day and makes a total of $512, how many apple pies did she sell?

the solution is h=10 because you add 9 to each side of the equation.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
