How would I write an expression for the following? 20 less than a

n - 20

Thanks

You're welcome.

To write an expression for "20 less than a number," you can use the variable "x" to represent the unknown number.

To express "20 less than x," you need to subtract 20 from x. This can be written as:

x - 20

In this expression, "x" represents the unknown number, and "x - 20" represents the result of subtracting 20 from that number.
