tell whether this pair of expressions is equivalent.

9x+5/5 and 9x

1 answer

To determine whether the pair of expressions \( \frac{9x+5}{5} \) and \( 9x \) are equivalent, we need to simplify and compare them.

**Expression 1: \( \frac{9x + 5}{5} \)**

To simplify, we can distribute the denominator 5 to each term in the numerator:

\[ \frac{9x + 5}{5} = \frac{9x}{5} + \frac{5}{5} \]

This simplifies to:

\[ \frac{9x}{5} + 1 \]

**Expression 2: \( 9x \)**

This expression is already simplified.

Now, let's compare the two simplified expressions:
\[ \frac{9x}{5} + 1 \quad \text{and} \quad 9x \]

Clearly, \( \frac{9x}{5} + 1 \) is not equal to \( 9x \).

Therefore, the pair of expressions \( \frac{9x + 5}{5} \) and \( 9x \) are not equivalent.
