Which inequality is true when n=4? 2n >6 n+3<7 9-n≥(greater than or equal to) 13 (n)/(12) ≥ 3

Question

Which inequality is true when n=4?


`2n >6`

`n+3<7`

`9-n≥(greater than or equal to) 13`

`(n)/(12) ≥ 3`

Answer 1

To find out which inequality is true, we need to plug in n=4.


`2n>6`

`2(4)>6`

`8>6`

And since 8 is really greater than 6, this inequality is true! :)


`n+3<7`

`4+3 < 7`

`7 < 7`

7 is not less than 7. So this inequality is false.


`9- n \geq 13`

`9-4 \geq 13`

`5 \geq 13`

5 is not greater than or equal to 13, so this inequality is false


`(n)/(12) \geq 3`

`(4)/(12) \geq 3`

`(1)/(3) \geq 3`

And 1/3 is not greater than 3, so this inequality is also false.
