The equation that relates vandw isv=235w.

Step by step solution

01

Step 1. Given information  

v varies inversely with w.

v=18w=13

02

Step 2. Finding the equation. 

Write the formula for inverse variation

y=kx

Substitute v for y and w for x in the equation.

v=kw

Substitute v=18&w=13in the equation.

v=kw18=k1318脳13=kk=235

Substitute value of k in the equation.

v=kwv=235w
