Question

A number n is more than 9 units from 3

Answer 1

n < 9 +- 3
N is less than 9 plus/minus 3

Answer 2

Answer:

The required inequity is: $|n-3|\leq 9$

The required solution is: $-6\leq n\leq 12$

Step-by-step explanation:

Consider the provided information.

The given statement is A number n is more than 9 units from 3.

Let the number 'n' is more than 9 units from 3.

Since more than 9 unit is distance, and distance can be in both the direction so take the absolute value as shown.

$|n-3|\leq 9$

Thus, the required inequity is: $|n-3|\leq 9$

Now we can solve it as shown.

$-9\leq n-3\leq 9$

$-9+3\leq n\leq 9+3\\-6\leq n\leq 12$

Hence, the required solution is: $-6\leq n\leq 12$
