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

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

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

I really need help please help me

Answer:

5.667 yards of fabric was used to make a cape

Step-by-step explanation:

(Total Yard of Fabric)1/3 = (What's Used)

Total Yard Fabric = 17

What's Used = x

1 third = 1/3

(17)1/3 = x

x = 17/3 or about 5.667 yards of fabric used

Double Check:

5.667/17 = 0.3334 which is about 1/3

If you want to find how much he has left:

1 - 1/3 = 2/3

17(2/3) = x

x = 34/3 or about 11.333 yards of fabric left.

Double Check:

11.333/17 = 0.6666 which is about 2/3
