00:00Number A is directly proportional to B plus 2 and inversely proportional to C.
00:03Given that A is 6, B is 1, and C is 3, what is A when B is 2 and C is 12?
00:09Let's set up our proportions right away, guys.
00:11If the number A is equal to B plus 2, then we will write it as A divided by B plus 2, right?
00:18It's also inversely proportional to C.
00:20Multiply by C. This is for number A.
00:23This is also equal to... our proportionality constant K becomes equal.
00:26So what did our friends tell us?
00:27The question asks what the value of A is if A = 6, B = 1, and 1 plus 2 multiplied by C = 3.
00:36I'm saying A multiplied by A.
00:38If B is 2, then C is 12.
00:45We're being asked about our A, folks.
00:48Okay, let's do it right away.
00:49This part has been simplified to 3, right guys?
00:524 1 3 1 2
00:55We find our A to be 2 from here.
00:59while A our Spa.
