Took must make a 92 on the next test. 
(81+84+84+69+76+x)/6=81
(394+x)/6=81
Multiply by 6 on both sides
394 + x = 486
Subtract 394 from both sides. 
x= 92

Answer:
Given:
x-y=-4
2x+y=4
Step-by-step explanation:
x-y=-4
2x+y=4
add both the equation, we get
⇒  x-y=-4
   2x+y=4
⇒3x=-4+4
⇒3x=0
⇒x=0
∴ to find the value of y, put the value of x in any one equation
⇒x-y=-4
⇒0-y=-4
⇒-y=-4
⇒y=4
∴ x=0, y=4
 
        
             
        
        
        
you literally just need to add a single letter. You need to place the letters “t” and “r” to the word “shore”. After you do that, the word becomes “shorter”. Another possible answer is the word “Sorte”.
