Question

Can someone give me a refresher on this

Suppose 𝑤 and 𝑥 vary inversely and 𝑥 = 1.25 when 𝑤 = 8. Find 𝑥 when 𝑤 = 15.

Answer 1

\(w=\dfrac{k}{x}\)

\(8=\dfrac{k}{1.25}\) can you solve for \(k\)?

Answer 2

10

Answer 3

so \(w=\dfrac{10}{x}\)

Now plug in \(15\) for \(w\) and solve for \(x\)

Answer 4

2/3
