Question

A choreographer uses a number line to position dancers for a ballet. Dancers A and B

Answer 1

Answer:

the coordinates of dancer c = 15

Step-by-step explanation:

the coordinates of dancer A is 5 and the coordinate of dancer B  is 23

the distance between dancer A and dancer B is

distance = 23 -5

= 18

so,

as dancer C is 5/9 of the distance from dancer A to dancer B, find the 5/9 of the distance .

5/9 of distance = 5/9(18)

                    = 10

add the above value to coordinates of dancers A to find the coordinates dancer C

coordinate of dancer c  = 10 + 5

                                         = 15

hence , the coordinates of dancer c = 15

Answer 2

First we will calculate the distance AB. 
$AB=B-A=23-5=18.$
If C is 5/9 of the distance, mathematically speaking that means:
$C= \frac{5}{6} *AB= \frac{5}{6} *18=15.$
R: The coordonate of C is 15.
