Answer:
6080
Step-by-step explanation:
5x8x152=6080
 
        
                    
             
        
        
        
X = 8 
because 8 x 2 = 16 
16 - 9 = 5
5 x 3 = 15
        
                    
             
        
        
        
Answer:1 computer : 8 students
Step-by-step explanation:
if there are 9 computers it would originally be 9 : 72 but that can be reduced since 9 is a factor of 72.
 
        
                    
             
        
        
        
15x-10=20
 +10 +10
15x=30
\15 /15
x=2
you add 10 to both -10 (they cancek eachother out) and 20 (equals 30) 
Then you divide 30 by 15 (equals 2) and 15 by 15 (they cancel eachother out) 
Then you get x=2
        
                    
             
        
        
        
Answer:
Slope: 2; Y-Intercept: (0,3)
Step-by-step explanation:
As you can see from the graph, it rises 4 and runs 2. So, the slope is 2. It intersects the y axis at (0,3)
