Question

Write the English phrase as an algebraic expression. Then, simplify the expression. Let x represent the number.
The difference between the product of nine and a number and twice the number.
What is the algebraic expression?

Answer 1

Mina,

So look first at the grouping words here. Difference says you are going to subtract two things.  What are those things?  the product of some things and twice the number. ; the word product acts like a grouping word. 

 

Difference between product of nine and a number AND twice a number

Product is 9x, twice a number is 2x, you subtract those two and get 9x - 2x

Then you simplify.
