Answer:
B. 9
Step-by-step explanation:
We are given that <em>y</em> varies inversely with <em>x</em>. Recall that inverse variation has the form:
Where <em>k</em> is the constant of variation.
We are given that <em>y</em> = 18 when <em>x</em> = 12. Hence:
Solve for <em>k. </em>Multiply both sides by 12:
Thus, our equation is:
We want to find <em>x</em> when <em>y</em> = 24. Substitute:
Cross-multiply:
Divide both sides by 24. Hence:
Our answer is B.
