Five brothers are going to take turns watching their family's new puppy. How much time will each brother spend watching the puppy in single day if they all watch him for an equal length of time?

4 hours 48 minutes

Step-by-step explanation:

Right now, in this problem the whole set comprises of a single day and you know that there are 24 hours in a day.

In order to solver the problem,you have to draw a number line of length 24 and then separate it into 5 equal parts.  (because there are total five brothers)

or simply, just divide 24 by 5.

= 24/5  => 4 hours

lets convert 4/5 hour to minutes, as you know there are 60 minutes in one hour.

therefore, 4/5 x 60= 48 minutes.

Each brother will spend 4 hours watching the puppy in single day, which is likewise 4 hours 48 minutes

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
