Answer:
3 <= x <= 8
Step-by-step explanation:
A number is denoted as an arbitrary variable, let's call it x.
We have a double inequality:
1. No more than 8 means less than or equal to 8
2. No less than 3 means greater than or equal to 3
3 <= x <= 8
Answer:
12 ≤ n ≤ 17
Step-by-step explanation:
Let n - number
Nine less than a number: n - 9
is no more than 8: ≤ 8
and no less than 3: ≥ 3.
We have the inequality:
[tex]3\leq n-9\leq8\qquad\text{add 9 to all sides}\\\\3+9\leq n-9+9\leq8+9\\\\12\leq n\leq17[/tex]
