Answer 1

A child planted five beans. How many bean plants will grow? x equals the number of bean plants that will grow. There will not be more than five plants, but there could be less if not all of the beans grow.

X is less than or equal to 5

X ≤ 5

Answer 2

You can take the following example:

Rick earns $50 a day. For how many days should he work so he earns no less than $750.

It can be solved as follows:

Let the number of days Rick should work be = x

He earns $50 a day, so for x days he will earn 50x.

Now, his earnings cannot be less than $750. We can show this as follows:

`50x\geq 750`

We will solve for x now.

`x\geq 750/50`

`x\geq 15`

This means here that Rick will have to work for at least 15 days to get $750. If he will work less than 15 days, he will get less money.
