Yoko received a $80 gift card for a coffee store. she used it in buying some coffee that cost $7.58 purse pound after buying the coffee she had $57.26 left on her card how many pounds of coffee did she buy?

3 pounds

Step-by-step explanation:

7.58x + 57.26 = 80  subtract 57.26 from both sides

7.58x= 22.74 divide both sides from 7.58

x =3

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.
