-66, -52, - 48, -42
If you can have 2 medians (since there is only 4 numbers), it is -52 and -48
If you can only have one,then i believe you choose -50, because it is in between -48 and -52
hope this helps

Correct answer is B... You can plug in values for n.  Plug in 1 for n and the out put is 12.  Plug in 2 for n and the output is 13.5
 
        
                    
             
        
        
        
Hi there!
To solve this problem using substitution, we need to set x equal to a value and substitute it into the other equation.
Since
x - 4y = 5,
x = 5 + 4y
3x - 7y = 10
3(5 + 4y) - 7y = 10
15 + 12y - 7y = 10
15 + 5y = 10
5y = -5
y = -1
Now that we know y is -1, we can substitute it back into the equation to find x:
y = -1
x - 4y = 5
x - 4(-1) = 5
x - (-4) = 5
x + 4 = 5
x = 1
So, your answers are x = 1 and y = -1.
Hope this helps!
