Nine less than the product of

20
and Mabel's height

M x 20 - 9 = ?

(M stands for Mabel's height)

To find the answer, we need to multiply the value of 20 by the height of Mabel and then subtract 9 from the product.

Let's assume Mabel's height is represented by the variable 'h'.

The expression for the product of 20 and Mabel's height would be: 20 * h

Now, if we want to find nine less than that product, we subtract 9 from it: 20 * h - 9

So, the final answer to "Nine less than the product of 20 and Mabel's height" is 20h - 9.
