1. The sum of the number n and two
2. The quotient of the number 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:

${k}_{1}=n+2$
${k}_{2}=n\mathrm{/}9$
${k}_{3}=2n$
${k}_{4}=9-n$
${k}_{5}=n-9$
