I think the coordinates are 1, 10 but not positive because if you graph it you can see a kite in it so make the point close to 4,10
        
             
        
        
        
Answer:Fred has 13 9/10 minutes left for question C
Step-by-step explanation:
The total time that Fred has to do the three-problem quiz is 30 minutes.
He spent 10 7/10 minutes on question A. Converting 10 7/10 minutes to improper fraction, it becomes 107/10 minutes.
He spent 5 2/5 minutes on question B. Converting 5 2/5 minutes to improper fraction, it becomes 27/5 minutes.
Total time that Fred spent on question A and question B is 
107/10 + 27/5 = (107 + 54)/10
= 161/10 minutes.
The amount of time that he has left for question C would be
30 - 161/10 = (300 - 161)/10 = 139/10
= 13 9/10 minutes
 
        
             
        
        
        
To simplify, you just need to multiply 9 by both 3t and 4b separately:
9(3t + 4b) = (9)(3t) + (9)(4b) = 27t + 36b
That what to simplify means. Hope this helps!
