Join Vince Kotchian for an in-depth discussion in this video Understanding the variables in choices (VIC) technique, part of Test Prep: ACT.
- [Voiceover] Sometimes, ACT math questions have variables…and answer choices instead of numbers.…These questions can be done using algebra,…but sometimes it's easier to turn them into…arithmetic problems by using a technique called plugging in.…In other words, substituting numbers for those variables.…This video will demonstrate that technique.…So, here we have an example of a question…for which we can plug in numbers…because it is very easy to see…the choices have variables in them.…So, there are 3 steps to this plugging in technique.…The first step is invent numbers…for the variables in the choices.…
So, notice we got an n and we have an m.…So, it says a certain number, n, is nine…less than twice another number, m.…Ok, so let's see.…Let's pick some numbers here.…What if we have m be 10?…M is 10.…Ok, so what is that going to make n?…Well, n is nine less than twice m.…Twice m would be 20, and nine less than 20…would be 11.…So, n has to be 11 if m is 10.…
So, great, we have fulfilled step one.…Step two is just solve the question numerically.…
