Answer: The required value of the number v must be greater than or equal to 14.
Step-by-step explanation: Given that thirteen is at least the difference of a number v and 1.
We are to find the value of the number v.
Since thirteen is at least the difference of a number v and 1, so the difference must be greater than or equal to 13.
Therefore, we can write the inequality and solve as follows :
[tex]v-1\geq 13\\\\\Rightarrow v\geq 13+1\\\\\Rightarrow v\geq 14.[/tex]
Thus, the required value of the number v must be greater than or equal to 14.
