Answer:
5/42 is your answer take robot to complete
7 tasks = 5/6

1 hour / (5/42 hour/task) = 15/2 tasks = 8.2 tasks.
half a task isn’t a complete task, so the answer is 8 tasks.
 
        
             
        
        
        
From this question I take it that you need to know what is 130% of 45 mg. 130% of 45 is equal to 1.3x45, which is 58.3. So, your answer is 58.3 mg of the vitamin.
 
        
                    
             
        
        
        
3x+22=10x-41
 -22 -22
----------------------
3x=10x-63
-10x -10x
-----------------
-7x=-63
divide by -7 on both sides
yep ur right its x=9
        
             
        
        
        
<span>you'll find the denominator is zero which isn't possible, so you'll get undefined. </span>
