Which of the following expresses the air temperaturein terms of the speed of a sound wave?$$\begin{array}{l}{\text { A) } t=\frac{a-1,052}{1.08}} \\ {\text { B) } t=\frac{a+1,052}{1.08}} \\ {\text { C) } t=\frac{1,052-a}{1.08}} \\ {\text { D) } t=\frac{1.08}{a+1,052}}\end{array}$$

All right. So the question is asking us to, um basically isolated the variable eso which the fine expresses the air temperature in terms of speed of sound they give us the equation is a so eh is equal to one zero. Ah, two plus one point zero eighty. So, in order self, this we're going to do has we're going to do her reverse Parent does which is order of operations over sort of operations. Eso when you're tryingto isolated, variable in your china factor something and trying to solve for something you do reverse pendants which is reverse sort of operations. So normal order of operations would be princes experience multiplication division this instruction from left to right. In this case, we're going to reverse penned this we're gonna do addition subtraction First, the monkfish division that we're going to explore and then princes in this case, right? We don't have any princes were having explains. So we don't worry about those. But we do have edition. We do have multiplication. So first steps going backwards, right, doing starting with the distraction since you have addition right here. Not so. Even just this. Plus the fact you know plus, technically hidden in front of the one thousand fifty two. We're going to subtract outside by one thousands. Wrong. Remember one thousand fifty two and that's going to give us our due there. On both sides, that's going to give us a minus. One zero five two is equal to one point zero eight t Not looking at the answer traces. Alright, that's actually gonna eliminate pretty much all the answer choices. Except for one. There's only one single and straight, which is letter, eh? So we already have the answer. Technically, already done now. But we can take and to you I don't want to stop right now. Let's continue this, but basically a minus one thousand fifty two. There's only one answer choice specifically with that, but think and potentially they could throw a curveball at us. So let's continue the process. So next we'd start with modification video. We have multiplication between tea and one thousand for one point zero eight on since we have Multivision between the two that were going to divide both sides by one point zero eight. So we all just have one points your men and that gives us tea is equal to a minus one zero five two. Now, part of the reason why we could tell that this is the process that we wanted to take here is that they had teal alone, right? So tea is going to be equal to that, too, Since the answer choices right, I always want to look at the entrances when I'm solving for these questions. Since the answer choice included right T is equaled, something that would help us identify that isolating, insolvent for teeth on says the end of the process there.
