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

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

[tex]2n>6[/tex]
[tex]2(4)>6[/tex]
[tex]8>6[/tex]

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

[tex]n+3<7[/tex]
[tex]4+3 < 7[/tex]
[tex]7 < 7[/tex]

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

[tex]9- n \geq 13[/tex]
[tex]9-4 \geq 13[/tex]
[tex]5 \geq 13[/tex]

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

[tex] \frac{n}{12} \geq 3[/tex]
[tex]\frac{4}{12} \geq 3[/tex]
[tex]\frac{1}{3} \geq 3[/tex]

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