Question 196977
<font face="Garamond" size="+2">


<i>w</i> jointly proportional to <i>u</i> and <i>v</i> means:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ w = kuv]


Substitute the given values:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 24 = k(0.8)(5)]


Now solve for the value of <i>k</i>


Once you have a value for <i>k</i>, substitute that value and the given values for <i>w</i> and <i>v</i> to solve for <i>u</i>.
