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 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)

Solution:

$k_1=n+2$

$k_2=n\mathrm{/}9$

$k_3=2n$

$k_4=9-n$

$k_5=n-9$
