To rewrite the equation \( \frac{5}{b} = 10 \) as two equations joined by "and," we can separate it into the two components: the equation itself and the condition that \( b \) cannot be zero (since \( b \) cannot be in the denominator).
So, the rewritten form is:
\[ 5/b = 10 \text{ and } b \neq 0 \]
It's important to specify that \( b \neq 0 \) because division by zero is undefined.
