Question

What is the coefficient of the term `18z` in the expression `0.5x+18z`?

Answer 1

`18` is the numerical coefficient of `18z`

`z` is the literal coefficient of `18z`

`1` is the coefficient of `18z`

Explanation:

There are different types of coefficient.

In as expression such as `3xy`

`3" "` is the numerical coefficient -the number part

`xy" "` is the literal coefficient - the letter part

`3x" "` is the coefficient of `y` -the part 'next to' `y`

`x" "` is the coefficient of `3y`

The question is therefore not very clear.

Which coefficient is being asked for?

`18` is the numerical coefficient of `18z`

`z` is the literal coefficient of `18z`

`1` is the coefficient of `18z`
