Explain how comparing 645 and 738 different from comparing 645 and 649
pantera1 [17]
For 645 and 738:
 
For these numbers we have that the difference between both is:
 738 - 645 = 93

 For 645 and 649:
 
For these numbers we have that the difference between both is:
 649 - 645 = 4

 Therefore, comparing the first two numbers of the second two numbers is different because the difference between the first two numbers is much larger.

 Answer:
 
The difference between the first two numbers is much greater than the difference between the second two numbers.

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>

Tim began with 40 comics
