Hello!</h2>
The answer is: There are a total of 16 skits in the video.
<h2>Why?</h2>
From the statement, we know that the total length of the video is 101 minutes and it contains a 5-minute introduction, the rest of the minutes are short skits (which are 6 minutes long each one).
So, we need to write the following equations:
First equation:

Second equation:

Where,

So, replacing and substituting the second equation into the first equation we have:

So, there are a total of 16 skits in the video.
Let's prove it substituting "n" into the first equation:

Have a nice day!
To complete the square we get the coefficient of x, divide it by 2 then square it.
-3/4 divided by 2 =
-3/8 and then squared it equals
9 / 64
answer is a
40x+30x=315
70x=315
315/70=
4.5 hours
12:00 noon + 4.5 hours = 4:30 pm
