Q. Khalil is

3

years older than his cousin Noah. Khalil wants to write an equation for his own age

(k)

in terms of Noah's age

(n)

.

\newline

How should Khalil write his equation?

\newline

Choose

1

answer:

\newline

(A)

k-n=3

\newline

(B)

k-3=n

\newline

(C)

n+3=k

Understand Relationship: Understand the relationship between Khalil's age and Noah's age. Khalil is $3$ years older than Noah. This means that if we know Noah's age $(n)$ , we can find Khalil's age $(k)$ by adding $3$ to Noah's age.
Write Equation: Write the equation based on the relationship. $\newline$ Since Khalil is $3$ years older than Noah, the equation representing Khalil's age in terms of Noah's age would be $k = n + 3$ .
Match Equation to Options: Match the equation to the given options. $\newline$ Comparing the equation $k = n + 3$ with the options provided: $\newline$ (A) $k - n = 3$ (This would mean Khalil's age minus Noah's age equals $3$ , which is correct.) $\newline$ (B) $k - 3 = n$ (This would mean Khalil's age minus $3$ equals Noah's age, which is incorrect.) $\newline$ (C) $n + 3 = k$ (This is the same as $k = n + 3$ , just written in a different order, so it is also correct.)
