@Juliusmattos12 and @Ayra2000: Kindly do NOT provide direct answers, and especially do not do that if you're not even sure yourself.

The goal of Open Study is to help students develop their own problem solving skills, including finding their own answers. You defeat this purpose if you hand out answers without involving the person who asked the question. Do not repeat this behavior, please.

Answer 8

I have z apples right now, and when my friend gives me 4 apples, wouldn't I then have z+4 apples?

Answer 9

well what exactly could "z" be?

Answer 10

actually i think ill just go with D. ill medal whoever helped the most

Answer 11

z is just a number.
It is called a "variable" however, because we don't know what number this "z" is. Or, in other words, "z" is an unknown number.

So, we use "z" (or other letters, like "x" in your question), to represent some unknown number.

Answer 12

(btw, D is wrong, so don't)

Answer 13

Answer 20

yupp

Answer 21

And what if I have 12 apples and my friend then gives me 2 apples. How many apples do I have then?

Answer 22

youll have 14 yummy apples cx

Answer 23

Yes

Answer 24

And what if I had "x" number of apples, and my friend gave me 2 apples. How many apples do I have after that?

Answer 25

im not sure 2+?=?

Answer 26

Well, I would have x+2 number of apples.

Answer 27

I had "x" apples before.
My friend gave me 2 more apples.

Now I have x+2 apples.

(Remember that x just represents an unknown number)

Answer 28

is this at least somewhat understandable?

Answer 29

well than x could be anything??

Answer 30

Yes, but, "x" is just some number that we don't know.

Answer 31

well than how do i know what it equals

Answer 32

x is not any number that we don't know - i.e. it doesn't arbitrarily change every moment. It is a consant/same value, except that we don't know what this value is.

So if I have "x" apples -- some unknown amount of apples.
And then my friend gives me 2 to apples.

Then, I have 2 more apples than that unknown amount of apples,
this is same as saying, - I have 2 more apples than "x",
this is same as saying, - I have 2+x apples

Answer 33

so x is ....1 apple.?

Answer 34

x is any unknown amount of apples.

Answer 35

Ok, this might be a difficult concept to understand, but let me say this differently...

Answer 36

okayy

Answer 37

Suppose that you have a big tank with oranges, and you don't know how many oranges you have in the tank.

Answer 38

can we speed up the paste just a little my test has a timer and my teachers will think i was waisting time...<3 "

Answer 39

well, I am trying to explain the concept that you seem to not understand...

Answer 40

ok sorry but go on..

Answer 41

You have a big tank with oranges, and you don't know how many oranges you have in the tank.

You will then say that you have "an unknown amount of oranges"

(It could be anything, it could be 50 oranges 124 oranges, or 78888 oranges, (etc) ... just that this amount of oranges is same - it is not something that changes orbitrarily)

You want to say this differently, instead of saying that you have "an unknown amount of oranges" , you will say that you have "x number of oranges"

Answer 42

HEY I GOT IT NOW!!!!! :D :D CX CX

Answer 43

The idea is that you are using a letter (like "x") to represent an unknown amount of something.

Answer 44

So you can say that your tank contains "x number of oranges"

Answer 45

no no no!

Answer 46
