Each tile costs 3, and he wants to spend less than 1,000.

I mean 0 minus 5.

Minus 100 minus 5.

5 minus 5.

It just keeps going on in both directions.

Here is our answer.

So 3x is going to be the total cost of purchasing the tiles.

If we have the same sign divided by the same sign we're also going to be positive.

Anything that's in between these two numbers is going to have an absolute value of less than 12.

We have 2 and 7 8.

If we say x is positive, then definitely.

Less than 1MiB

But then we can shade in everything below 40.

I just swapped the two sides.

And I'll write and like that.

Now over here, subtract 3 from both sides.

You get a 2 and a 1, it's 10.

You under 16?

Less than a minute.

Notice subtlety here. Even outcome 11 is okay.

Let me write it this way

But remember, this number has to be greater than or equal to one, which it is, AND less than ten!

She did a lot of exposure, may be too much This is 19 and above only!

Yeah, that's zero.

Well, it's a minimizing node, so the least it could be is 2.

So the left hand side is just x. x is less than negative 4 divided by 4 is negative 1. x is less than negative 1.

You have 0, minus 1, minus 2.

3x is how much he spends if he buys x tiles.

If you want to know, what is the probability that I get a value less than 20?

Five hundred and twenty six dollars and ninety cents, minus fifteen dollars and eight cents.

It'll go from 10 3, all the way down to negative infinity.

Let's do one more.

Entrance is restricted to those above 18.

I should think she is under thirty.

Precision is less than 1.0, fixed

I think it'll be useful here. The number we are going to do. We are starting from 31 and adding 29 to it.

Since we are adding a number less than 31, we are not going to get all the way back to 0.

Same drill.

less than 2 and 1 2, that means that the distance from x to 0 is less than 2 and 1 2.

Cookie is under 5 years old.

That happens in less than 2 of our missions.

Recent technologies like the PC, the web, cell phones were under a decade.

Well this is the graph of f of x. And when is f of x less than 0?

But it's heart stopping. It's mind blowing stuff.

5x is less than 4.
