# Expressions

Let k represent an unknown number, express the following expressions: 1. The sum of the number n and two 2. The quotient of the numbers n and nine 3. Twice the number n 4. The difference between nine and the number n 5. Nine less than the number n

Result

k1 = (Correct answer is: n+2) k2 = (Correct answer is: n/9) k3 = (Correct answer is: 2n) k4 = (Correct answer is: 9-n) k5 = (Correct answer is: n-9) ### Step-by-step explanation:

${k}_{1}=n+2$
${k}_{2}=n\mathrm{/}9$
${k}_{3}=2n$
${k}_{4}=9-n$
${k}_{5}=n-9$ Did you find an error or inaccuracy? Feel free to write us. Thank you!
