(x2 subtracted by x1 divided by 2, y2 subtracted by y1 divided by 2) is the midpoint formula.   
(2-3/2, 5-6/2)= (-1/2, -1/2) which is the answer/
        
             
        
        
        
Answer:
107810
Step-by-step explanation:
You can use the order of operations! So we start with 99^3/9. That is 99^2*11. So now let’s do 99/99, it’s 1. So 99^2*11 is 107811, so the answer is 107810.
 
        
                    
             
        
        
        
Each large box weighs 15 kilograms and each small box weighs 13.5 kilograms.
Step-by-step explanation:
Let, 
Weight of large box = x 
Weight of small box = y 
According to given statement; 
5x+2y=102      Eqn 1
3x+8y=153      Eqn 2
Multiyplying Eqn 1 by 4 

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 17

Putting x=15 in Eqn 2

Dividing both sides by 8 

Each large box weighs 15 kilograms and each small box weighs 13.5 kilograms.
