Answer:

only d is true since 5(3) = 15, which is greater than 14. 2.8 times 5 is exactly 14, so a and b don't make sense

Answer:

#16 answer is D

#12 answer is A

Step-by-step explanation:

The reason #16 is D is because, if the variable "Y" is 1.5 then that would make the inequality 7.5 > 14. This is NOT true. If "Y" were 2, then it would be 10 > 14. This is NOT true either. If "Y" were 2.8, then that would make it 14 > 14. THIS IS NOT true either. BUT if it was 3, then that would make it 15 > 14. Which IS true.

Now the reason #12 is A is because the sign " $\geq$ " means "Greater than or equal to, no less then." And the SHORTEST/ Minimum height is 42 $\frac{1}{2}$ inches.

Hope this helps!
