ok oh and i see you have answer choices, obvious the last two are rather silly because working together is evidently quicker than working alone

Summer math packet :)))

Answer 18

heck i will make a guess that they want you to solve
\[\frac{1}{15}+\frac{1}{x}=\frac{1}{20}\] which gives \(x=-60\) go with 60 and tell your teacher that satellite says they should be ashamed
