Answer:

Step-by-step explanation:
Proportional functions can be represented by  , where
, where  is a constant of proportionality and
 is a constant of proportionality and  represents any point the line passes through.
 represents any point the line passes through.
In the graph, we can see the line passes through (20, 40). Therefore, we can plug in these coordinates to find the constant of proportionality:

 
        
                    
             
        
        
        
8x+15=7
answer: x= 1 hope this help
        
             
        
        
        
Answer:
there are 8 ounces in a half pound
Step-by-step explanation:
 
        
                    
             
        
        
        
6,00 because you have to add them up then divide the the last nimber and you should get 6,000
        
             
        
        
        
So,
#1: 

Convert to like improper fractions.

Add.

So, one solution could be 

.
Another solution could by 9.  There is also 10, 11, 12, etc., and all numbers in between.
#2: 

Convert into improper fraction form.

Multiply.

Cross-cancel, and we have our final result.

k < 96
96 is not a solution.
95 is a solution.
So is 94, 93, 92, etc, and all numbers in between.
