Answer:
p = -3
Step-by-step explanation:
Apply algebra to the equation by subtracting 4 from each side, that way it will cancel out at least the 4 next to p. It should now look like this: p = -3
Because we can't make anymore moves and the expression clearly states what p is, we're done!
 
        
             
        
        
        
Answer:
8
Step-by-step explanation:
Set up a ratio problem:
25 hours/2 tests = 100 hours/x
25x = 200
 x = 8
 
        
                    
             
        
        
        
A) Gigabytes = x
B) 35+5x = 25+10x
 10 = 5x
 2 = x
C) After 2 gigabytes, the wireless services will cost the same ($45)
        
             
        
        
        
= 394 R 1
= 394 1/3
1183 divided by 3 equals 
394 with a remainder of 1
