David and jon are placing coffee orders for their friends. david order 10 large cups of coffee. jon order 4 fewer large cups than david. jon pays for his orders with a $50 bill. jon wants to know how much he spent on coffee.

Jon spent $70 for his coffee

Step-by-step explanation:

David - 10 large cups of coffee

Jon - 14 (10 + 4 fewer large cups) cups of coffee

David pays $50 for 10 large.

Cost for each cup - 50 ÷ 10 = $5

Jon pays how much for 14 cups?

14 × $5 = $70

That's a lot of coffee for two guys.

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.

the answer would be c:   ax + b = ax + c
