A choreographer uses a number line to position his dancers for a ballet. Dancers A and B have coordinates 7 and 25, respectively. Find the coordinates of dancer C if dancer C is standing at a ration of 5:1 between dance A and B.

22

Step-by-step explanation:

5:1 means 6

25-7=18 lines

18 lines / 6 = 3 lines per time

5*3 = 15 lines from A to C

7 + 15 = 22 lines

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
