Question

How do you write an algebraic expression for the phrase "thirty divided by a number"?

Answer 1

`30/x`

Explanation:

Let's call our number `x.`

When converting words into algebraic expressions, "a number" should be your cue to introduce an unknown variable (generally denoted by `x`), unless we're told exactly what that number is.

Thirty divided by a number is just thirty divided by `x.`

`30/x`
