Write a variable expression for each word phrase?
Hint: "9 less than k" means "k - 9", because "less than" in this context means subtract: "subtract 9 from k", or in mathematical notation "k - 9." One needs to associate English idioms with arithmetic expressions: less than k => k - more than => + times => multiply => X or * twice => 2 times, or 2 X, or 2 * sum => add => + plus => + divide => / I don't want to explain them all; but hopefully there are more examples (explained) in your textbook, at the beginning of the section, before the problems start.

What are the best practices on using the full word instead of a number to represent quantities in English text?
I want to add to Sean Owczarek's answer.

Sometimes round numbers go either way, depending on context (fifty times/50 songs)Spell out if the number is in the millions (ten million), unless it is a decimal number (10.5 million), a fraction (10 millionth), or a dollar amount ($10 million).
