Answer:

Step-by-step explanation:


- In order to combine these two equations, an idea you need to keep in mind is finding a way of setting these equations as equal to each other. I saw that each equation shared a common value,  . In this case, we need to isolate . In this case, we need to isolate in the first equation so that both equations in the first equation so that both equations . .

 
 


- With this, we now know that both  and and are equal to are equal to , so we can set them equal to each other. , so we can set them equal to each other.



- Reply to this if anything I'm saying or doing is confusing in any way, or if you find a mistake. :) Solve for  . .

Step-by-step explanation:
To easily solve this problem, we apply a rule of three
-916 inch ---------------------------------- 3 hours
x inch ---------------------------------- 8 hour
x = 916 inc * (8 hours / 3 hours)
x =  2442.66 inch
The nearest number for this value is option D
(Lets remember we are talking about average values)
 
        
             
        
        
        
The LCD of 24 and 23 is 552, so 276/552 - 240/552 = 36. After simplifying 36/552, you get 3/46 and that is your answer.
