Tony's current scores are 22  and 25.
Let x = Tony's next score.
To make the lower required score of 27,
(x + 22 + 25)/3 = 27
x  = 81 - 47 = 34
To make the upper required score of 32,
(x + 22 + 25)/3 = 32
x = 96 - 47 = 49
Answer:
Tony should score between 34 and 49
        
                    
             
        
        
        
Answer:
3
Step-by-step explanation:
To find the average add all these numbers together, then divide by how many numbers you have.



 
        
             
        
        
        
-7x - 2y = 19
4x + y = -12
Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)
-7x - 2y = 19
8x + 2y = -76
Add equations together
x = -52
Plug x value into an equation
4(-52) + y = -12
Solve for y
-208 + y = -12
y = 196
Hope this helps! ;)
