Absolute Value Notation/Inequality and Interval Notation

The distance between x and 5 is 3, what is the solution to this and notation?

The distance between -4 and x is 7, what is the solution to this and notation?

The distance between x and a is b, what is the solution to this and notation?

Use both inequality and interval notation to describe the following sets.

a) z is at least 10

Find inequality and interval

b) y is no more than 25

Find inequality and interval

Thanks, this is for Algebra 2 Honors and was just having some problems with these.
