The table shows how the height of a stack of DVDs depends on the number of DVDs. What is a rule for the height?
2 answers:
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Number of DVDs Height
2 18
3 27
4 36
Since there is direct proportion between number of DVDs and height.
We need to find if the number of DVDs is n, then height would be
Hence, the rule for the height for n is h = 9n.
Option 'A' is correct.

Answer: s = 36
Step-by-step explanation: The key to solving multistep equations is isolating the variable. This is why I first subtracted 14 on each side. This left me with 1/3s=12. Then, to isolate "s" even more, I didvided by 1/3 on each side. This gave me s = 36 as an answer.
To divide by a fraction, use "keep change flip." Keep the first mumber, change division to multiplication, and flip the fraction. I included a picture of me doing this.
