Which point is between the other two points? find coordinates of D and F

Point D is between points C and F as the diagram shows. Without using a visual aid, you can tell based on how CD and DF are ordered. Note how the "D"s in CD and DF are adjacent when you place them together

CD DF ---> CF

That is one way to think about it. Although, for me, a visual guide is better.

Point C is at location 20 on the number line. We move 3 spots over to get to point D, so D is at 20+3 = 23 on the number line. Then we move another 5 units to the right to get to point F which is at 23+5 = 28

C = 20

D = 23

F = 28

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
