Which of these is the algebraic expression for "nine less than some number?" Fraction 9 over k Fraction k over 9 9 − k k − 9. MIDDLE

Answer 1

Answer: k - 9

We have some number k and we take 9 from it to end up with k-9, which represents 9 less than k.

For example, if k = 12, then k-9 = 12-9 = 3. So 3 is nine less than the number k = 12.
