The answer is: 2(m+1)
First combine like terms.
<em>we do 6m-4m which is 2m</em>
2m+2=?
Second we factor. We notice that both terms have 2.
2(m+1)
<em>by distributive law, the 2 is distributed to m and 1.
</em>
 
        
             
        
        
        
Answer:
{d,b}={4,3}
Step-by-step explanation:
 [1]    11d + 17b = 95
   [2]    d + b = 7
Graphic Representation of the Equations :
    17b + 11d = 95        b + d = 7  
  
 
Solve by Substitution :
// Solve equation [2] for the variable  b 
 
  [2]    b = -d + 7
// Plug this in for variable  b  in equation [1]
   [1]    11d + 17•(-d +7) = 95
   [1]    -6d = -24
// Solve equation [1] for the variable  d 
   [1]    6d = 24 
   [1]    d = 4 
// By now we know this much :
    d = 4
    b = -d+7
// Use the  d  value to solve for  b 
    b = -(4)+7 = 3 
Solution :
 {d,b} = {4,3} 
 
        
                    
             
        
        
        
C would be your answer and here is how you would solve the problem.
 
        
        
        
A,b are 8,2. its an easy guess.
now that makes it easy
        
             
        
        
        
Let s be standard and h be high-quality versions of the song.
To figure this out, let's make a system of equations: 
2.5s + 4.5h = 5740
h = 4s
First substitute the second equation into the first for h.
2.5s + 18s =5740
Then combine like terms.
20.5s = 5740
Lastly, divide each side by 20.5 to get the number of standard downloads: 
s = 280
Hope this helps!
