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.
