4) Determine a value for a number, n, that makes the following statements true
3.876 +n is greater than 4.424
and 3,876 - n is greater than 3,326​

Answer 1

`\large\boxed{0.548<n<550\to n\in(0.548,\ 550)}`

Explanation:

3.876 + n > 4.424 subtract 3.876 from both sides

3.876 - 3.876 + n > 4.424 - 3.876

n > 0.548

3,876 - n > 3,326 subtract 3,876 from both sides

3,876 - 3,876 - n > 3,326 - 3,876

-n > -550 change all signs

n < 550

n > 0.548 and n < 550 ⇒ 0.548 < n < 550
