Hey there :)
9( n - 4 ) - 4n ( n - 4 )
We can take ( n - 4 ) as common as both are getting multiplied by ( n - 4 )
We can join 9 - 4n together
Therefore, the final answer will be ( n - 4 )( 9 - 4n )
Answer:
25%
Step-by-step explanation:
So first we need to find out how many hours the school has class. Its 4 hours from 8 to noon, then another 2 from noon to 2. This means the school has class 6 hours a day.
Now we need to figure out the percent. we need to have hours of school over total hours or 6/24
6/24
we can simplify this by dividing both sides by 6
(6/6)/(24/6)=1/4
1/4 is 25%
The school holds class for 25% of the day
