    Answer:

    No unless x is being used to define only elements of an integer set.

    Step-by-step explanation:

    No, not in general unless x is defined as a integer or a subset of the integers like the naturals, whole numbers….

    Usually 6<=x<=10 means all real numbers between 6 and 10, inclusive. This means example that 6.6 or 2pi are in this set with infinitely other numbers that I can’t name.

    {6,7,8,9,10} just means the set containing the numbers 6,7,8,9,10 and that’s only those 5 numbers.
