The equation which represents the people that want to visit the museum and the exhibit is 8n+5n. 
As you can see, the variable n is present in both terms 8n and 5n of the equation, so we can now factor the equation. You create parenthesis in which you put inside 8+5 and then you throw the variable n outside the parenthesis, and you get at last:
8n + 5n = (8+5)n 
Hope this helps! :D

Answer:
5 1/3 hours.
Step-by-step explanation:
Ashley prepares 1 bag in 2/3 minutes.
One friend takes 2/3 + 3/4 * 2/3 = 7/6 minutes to make 1 bag.
4 of her friends can make 1 bag in 7/6 * 1/4 = 7/24 minutes.
If it takes x minutes for  Ashley and 4 friends to make one bag then we have:
1 / 2/3  + 1 / 7/24 = 1 / x
3/2 + 24/7 = 1/x
Multiply through by 14x:
21x + 48x = 14
x = 14/69 minutes.
So the  time to make 1575 bags = 1575 * 14/69
=  320 minutes.
 
        
                    
             
        
        
        
78 rounded to the nearest tenth is 80
