Question

| n | = 3.5 what are the values for n will make the expression true?

Answer 1

The given expression is,

`\lvert n\rvert=3.5`

So we know that, the absolute value of a number is its distance from the origin, say 0. SInce the distance cannot be expressed in negative values, absolute values are always expressed as positive numbers. FOr example,

`\lvert-x\rvert=\lvert x\rvert=x`

Therefore, the values that make the given expression true can be,

`\lvert n\rvert=3.5\Rightarrow n=-3.5\text{ or n=3.5}`
