Hi again! 
2x + y > 8 
The correct answer is option D 
-------------------------------------------
Honestly I don't think we can solve the equation to find the answer. What we can do is to find the boundary line. (I think you know what that is) After that, shading the appropriate area. 
y > -2x + 8 
Again, credit to my beautiful graphing calculator. Here is how it looks like. 
 
        
             
        
        
        
2/3 divide by 5 is 2/15
Remember keep change flip 
2/3 times 1/5 is 2/15 
Hope this helps!
        
             
        
        
        
Answer:
60 books
Step-by-step explanation:
let the number of books Willy has be x , then
Tammy has 4x books
Willy has 180 fewer books , that is Tammy has 180 more than Willy , so
4x = x + 180 ( subtract x from both sides )
3x = 180 ( divide both sides by 3 )
x = 60
Thus
Willy has 60 books andTammy has 4 × 60 = 240 books
which is 180 more than Willy
