In classical mechanics, the three base dimensions are length which is already given in the question, mass and time. Mass refers to the amount of substance present and this is usually expressed in g, kg, lbs, and others. Time is the measured moments that have passed from different events and usually expressed in seconds.

Tim sold half of his comics collection and then bought 16 more. If he now has 36, how many did he begin with?

STALIN [3.7K]

Tim began with 40 comics

Further explanation:

The equation involve linear equation as there is only one object i.e. comic books

So,

Let x be the number of comic books Tim began with

Then after selling half comics Tim will have x/2 comics remaining

Now when he buys 16 more the expression will be:

$\frac{x}{2}+16$

He has total 36 books, then

$\frac{x}{2}+16= 36$

Subtracting 16 from both sides

$\frac{x}{2}+16-16= 36-16$

${\frac{x}{2}}= 20\\$

Multiplying 2 on both sides

${\frac{x}{2}}* 2= 20*2\\x=40$

<u>We can recheck, if he had 40, half of them will be 20 and adding 16 makes them 36.</u>
