### Transcript

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
