Okay so this is not too hard once you get the grasp of it. What you want to do is put everything with each other giving you the answer, -3x^2 +42x^2 -147x
        
             
        
        
        
Answer:
A. 3/10
Step-by-step explanation:
So the ratio is saying 2 units to 3 units.  What represents 1 unit when 1/5 is two units?  We cut it in half which is 1/10. 
Now we have 1 unit so we can easily find three by multiplying by three, or even just adding three together.  So that's 3/10.  
let me knowif you don't quite get it.
 
        
             
        
        
        
The response is 
<span>x greater than or equal to -9
</span>proof
8x - (5x + 4)>= -31, 3x- 4>= -31, 3x >= -27,  <span>x>= -27/3= -9
so </span><span>x greater than or equal to -9</span>
