Question

Which inequality is true when n=4?

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! :)

$n+3$
<u />$4+3 < 7$
$7 < 7$

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

$\frac{n}{12} \geq 3$
$\frac{4}{12} \geq 3$
<u />$\frac{1}{3} \geq 3$

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