W is directly proportional to U. If W = 5 w..

Question 1 Report

W is directly proportional to U. If W = 5 when U = 3, find U when W = $\frac{2}{7}$

\frac{6}{35}

\frac{10}{21}

\frac{21}{10}

\frac{35}{6}

Answer Details

W $α$ U
W = ku
u = $\frac{w}{k}$ ; $\frac{2}{7}$ x $\frac{3}{5}$
= $\frac{6}{35}$

W is directly proportional to U. If W = 5 when U = 3, find U when W = 27
