eminent are related by the equation M equals k times
and meaning kay is a numerical constant which we need
to find Yeah surprise surprise So when are we not
solving for variables Well the fact that emma's one twenty
when n is eight allows us to find kay and
then we just kind of have a simple ratio Here
we just plugged the values of m and and into
the equation M equals k times and and we get
one twenty is kate times eight Well we just divide
both sides by eight tow isolate k There k is
one twenty over eight which is fifteen So now that
we know okay well we confined m when and is
eleven We just plug everything in wright's fifteen times eleven
it's one sixty five and that's it The answer is
the sometimes the wording of these questions is way more
complicated than the math on why they do that They 00:01:11.257 --> [endTime] want a tricky of their kind of evil
