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

Answers

Answer 1
Answer:

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:

(x)/(2)+16

He has total 36 books, then

(x)/(2)+16= 36

Subtracting 16 from both sides

(x)/(2)+16-16= 36-16

{(x)/(2)}= 20\n

Multiplying 2 on both sides

{(x)/(2)}* 2= 20*2\nx=40

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

Which equation represents a vertical line ?
y = -x
y = 12
x = y
x = 12

Answers

y is a vertical axis
x is a horizontal axis
when drawing a line, the line drawn to them is perpendicular so lines only touching the x axis are vertical and lines touching only the y axis are horizontal

the
a vertical line is x=value

the only thing that works is x=12
A vertical line is any line in which x is constant.  The line x=12 is vertical, because x is ALWAYS equal to one number - it doesn't change, ever.
