Brilliant_brown [7]

Answer:

90 Minutes

Step-by-step explanation:

If he took 27 minutes to do 30% of his homework, then we can reverse the operation to find the total amount

30% is the same as 0.3, therefore you divide 27 by 0.3 because the 100% is 1, so by dividing you'll get the 100%.

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>
