Answer:
(-0.5,-2.5)
Step-by-step explanation:
x1+x2/2,y1+y2/2 that is the midpoint formula so just plug in the known numbers and solve 
2-3    4-9

2         2
x= -0.5
y= -2.5
 
        
                    
             
        
        
        
Answer:
   15
Step-by-step explanation:
Let n, d, q represent the numbers of nickels, dimes, and quarters. The problem statement tells us ...
   n +d +q = 37
   n = d +4
   q = n +2
___
Rearranging the second equation gives ...
   d = n -4
Substituting that into the first, we get ...
   n + (n -4) +q = 37
   2n +q = 41 . . . . . . . add 4 and simplify
Rearranging the third original equation gives ...
   n = q -2
Substituting into the equation we just made, we get ...
   2(q -2) +q = 41
   3q = 45 . . . . . . . . add 4 and simplify
   q = 15 . . . . . . . . . divide by 3

<em>Check</em>
The number of nickels is 2 fewer, so is 13. The number of dimes is 4 fewer than that, so is 9. The total number of coins is 15 + 13 + 9 = 37, as required.
 
        
             
        
        
        
No because 4/1 does not equal to 9/4 or 16/9
