Question

I'm confused on the first and second question​

Answer 1

Answer:

For the first question we are given $5k < 39$ and to solve for k that means that we will need to divide 5 from both sides.  This would remove the 5 from the left side and that would end up with us dividing 5 from 39 giving us $k = \frac{39}{5}\ or\ 7.8$.  $k=8$ wouldn't work because that doesn't fulfill the expression

For the second question we are given $\frac{k}{2}\leq 4$ and to solve for k that means that we need to multiply both sides by 2.  This would remove the 2 in the fraction from the left side and that would end up with us multiplying 4 by 2 and giving us $k\leq 8$.  $k=8$ would work because we have that k is less than or equal to 8 including 8.

Hope this helps!  Let me know if you have any questions

Answer 2

Answer:

First is not a part. second is a part

Step-by-step explanation:

So, what you want to do in this question is plug the value of k=8 into the inequality and see if it is still true.

For the first one,

5(8)<39

40<39, which is not true

For the second one,

8/2 ≤ 4

4≤ 4, which is true
