So 5
then 5 times 5
then 5 times 5 times 5
so it seems that for x rounds, there will be 5^x  
A: 4 rounds so 5^4=625 photos
B. see how many times 5 goes into 78125. the answer is 7 so 7 rounds
C. 1 million=1,000,000 so try big numbers
5^10=9,765,625 too big
5^9=1,9,53,125 too big
5^8=390625 too small
the minimum is 5^9 or 9 rounds
A:4
B:7
C:9
        
             
        
        
        
Answer: x=-1 and y= -3
Step-by-step explanation:
Solve for x, x+y=-4 
Minus y from both sides so it'll be X=-y-4 
Now substitute -y-4 in x-y=2 and solve for y
-y - 4 -y=2 
Add like terms, -2y - 4=2
Add 4 to both sides -2y=6
Divide both sides by -2  
 
y= -3
Substitute -3 in x=-y - 4
x=-(-3) - 4
- × (-3)= 3 
3 - 4= -1
x= -1
