Answer:
(8n/10)
8 × 5 = 40
40 ÷ 10 = <em><u>4</u></em>
 
        
             
        
        
        
Y2-y1/x2-x1
1-4/2-3
Slope is: -3/-1 or 3
        
             
        
        
        
           3 + 1 < 10
There's no question there, and nothing to solve.  That's a simple statement 
which, after simplifying it slightly, says " 4 < 10 ".
A statement with which, I'm sure, we can all agree.
        
             
        
        
        
35 is the 20% so you multiply 35x5=175. 175 is the whole thing so you minus 175-35=140 which is the remaining money so half of that is 70
