Answer:
n = 3
Step-by-step explanation:
subtract 1 from both sides to get:
-4n + 6 = -2n
then add 4n to both sides to get:
6 = 2n
then divide both sides by 2 to get:
3 = n
Answer:true
Step-by-step explanation:
b is the correct answer
Step-by-step explanation:
see the step in the picture
Slope-intercept form is

, where m is the slope and b is the y-intercept.
Here, we first need to distribute the 1/3.

Next, we add 3 to both sides of the equation.
Lets look at the hours they are open from. 9 am - 4:30 pm which is 7 and a half hours a day. Now we multiply 7 1/2 by the number of days they are open, which will be 7 1/2 * 255 = 1,912.5. This means that the library is open 1,912 1/2 hours a year.
I hope I've helped! :)
