The reason #16 is D is because, if the variable "Y" is 1.5 then that would make the inequality <em>7.5 > 14</em>. This is NOT true. If "Y" were 2, then it would be <em>10 > 14</em>. This is NOT true either. If "Y" were 2.8, then that would make it <em>14 > 14</em>. THIS IS NOT true either. BUT if it was 3, then that would make it <em>15 > 14</em>. Which IS true.
Now the reason #12 is A is because the sign " " means "Greater than or equal to, no less then." And the SHORTEST/ Minimum height is 42 inches.
