Question

The number of roses (r) in a garden increases when the number of weeds (w) decreases. Write the correct equation for this scenario, and solve for the number of roses when there are 5 weeds. Weeds Roses 10 20 20 10

Answer 1

Hello,


`r= (k)/(w) \\ \textrm{if w=10 then r=20} ==\ \textgreater \ 20= (k)/(10) ==\ \textgreater \ k=200\\\\ \textrm{if w=5 then }\\\\ r= (200)/(5) =\boxed{40}`
