The function f(x) is a function of the variable x.
To solve the function for x = 30, just plug in 30 for x. 
14 - 0.5(30) = -1
f(30) = -1
        
             
        
        
        
where is the rest of the information?
 
        
             
        
        
        
The answer is like this! 
the total number of marbles all together is 25, so that would be the denominator.
blue: 6/25- simplified= already in simplified form
red:10/25- simplified= 2/5
green:9/25- simplified= already in simplified form
so the answer to your question is 2/5. 
hope this helped!!
        
                    
             
        
        
        
The answer $1.72. you divide $24.50 by .07 and the answer comes out to $1.715 and then you round up and have 1.72
        
             
        
        
        
Answer:
x = - 7
Step-by-step explanation:
 - 3x + 7 = 28
 - 3x + 7 - 7 = 28 - 7
- 3x = 21
- 3x/3 = 21/3
- x = 7
 x = - 7
