Answer:
   EF = 13.1
   FD = 35.3
Step-by-step explanation:
The distance between two points on a number line is the positive difference between their coordinates.
EF = F - E = 19 -5.9
EF = 13.1
__
FD = F - D = 19 -(-16.3) = 19 +16.3
FD = 35.3

A librarian has 150 books to be placed on shelves with an equal number of books on each shelf. If k is the number of shelves to be used, then 150/k is the number of books on each shelf.
Example : lets say there are 10 shelves.....so k = 10
150/10 = 15 books on each shelf.
        
                    
             
        
        
        
9 because the symbols around -12 and -3 so they would just become positive number 12 and 3. Subtract them and you get 9 :)
