To rewrite the equation \( \frac{5}{2}x - 8 - 1 = 9 \) as two equations joined by "and," we first simplify the left side:

1. Combine the constants:
\[
\frac{5}{2}x - 9 = 9
\]

2. Now, isolate \( \frac{5}{2}x \) by adding 9 to both sides:
\[
\frac{5}{2}x = 18
\]

3. Next, solve for \( x \) by multiplying both sides by \( \frac{2}{5} \):
\[
x = \frac{2}{5} \cdot 18 = \frac{36}{5}
\]

4. The equation \( \frac{5}{2}x - 8 - 1 = 9 \) itself remains one part, while the other part needs to indicate a restriction.

Rewriting the equation and including a condition on \( x \) results in:
\[
\frac{5}{2}x - 8 - 1 = 9 \quad \text{and} \quad x \neq \text{(something that needs to be deduced)}
\]

None of the options provided seem to reflect the solution for \( x = \frac{36}{5} \) or the nature of any additional restrictions on \( x \).

However, we are asked to select an answer from the given options. Based on context, it’s common in equations like this to avoid certain values that can make either the given equation or any expressed restrictions valid based on function evaluation or to avoid undefined behavior. Let's examine them:

A. \( 5/2x-8 - 1 = 9 \) and \( x \neq 8 \)
B. \( 5/2x-8 - 1 = 9 \) and \( x \neq 4 \)
C. \( 5/2x-8 - 1 = 9 \) and \( x \neq -4 \)
D. \( 5/2x-8 - 1 = 9 \) and \( x \neq -8 \)

None of these ("and x ≠...") directly relate to the solution we've found or standard algebraic restrictions as there was no discontinuity in this particular equation set. So potentially you might want to check whether \( x \) needs to be avoided in a specific way based on evaluation, but typically none should logically apply here.

If we must choose an option:
- Based on general restrictions in equations to avoid singularities or errors, any choice can appear valid.

Recommendation: Clarify the context or calculation to derive the intended restriction, providing more alignment as the equation itself does not naturally lead to a negative restriction.
