Use absolute value and inequality notations to describe the following situations. You may use "`|`" for absolute value sign; ` < = ` for `\leq` and ` > = ` for `\geq`. e.g. you may use "`|x| \ > = \ 5`" for "`|x|\geq5`".
The distance between `x` and `16` is no more than `18`

The distance between `x` and `- 25` is at least `19`

`x` is at least `25` units from `0`

`x` is at most `16` units from `0`
