Answer: -3
Step-by-step explanation: substitute y and x into the formula y=k/x, and that is 4=k/-12. Then you multiply the -12 over, you get that k=-48. Then you substitute that into the same equation getting y=-48/x, but then you see that y should be 16, so then it would be 16=-48/x. Then, you flip the two fractions to make it more simpler looking like 1/16=x/-48x. Then you multiply the -48 over, getting x=-3.

Answer: its C
Step-by-step explanation: cause i did that already
Since 30 lights are 40% of them:
30*2= 60
Since 2*40= 80
We still need the 20 percent.
Half of 40= 20.
30/2= 15
So, 15+60= 75
75 is the number of lights on the tree.
I hope this helps!
