Find the Sum: Solving 48 + 5 Addition Expression

To solve this problem, we need to determine which expression is equivalent to $48+5$. The sum $48+5$ equals $53$. We will rewrite $5$ as the sum of two numbers that add to 5, matching one of the provided choices.

Let's decompose $5$ in potential ways: $5 = 2 + 3$. Now let's rewrite the equation using this decomposition:

$48 + 5 = 48 + (2 + 3) = 48 + 2 + 3$

This step has shown that $48+2+3$ equals $53$, the same result as $48 + 5$.

Therefore, the expression equivalent to $48+5$ is $48+2+3$, corresponding to choice 2.
