Answer: Answer below.
Step-by-step explanation: If x is pi, and y is 1/pi, then multiplying x by y is 1; yes. So, for y, 1 is being divided by pi. The opposite of division is multiplication. If you multiply 1/pi by pi, the pi in the denominator cancels. Just how if it is 5x = 10, dividing by 5 cancels it on the left side, and gets you x = 2.
This is general for everything. If you multiply 2 by 1/2, you get 1. This is because dividing is also like multiplying by its reciprocal. 1/2's reciprocal is 2/1, and multiplying leaves you with 1. Go and use a calculator, it's correct. Actually, any problem a/b × b/a = 1.
I think the answer is A. Or the answer is A.

Part A:
90.10 = 0.30x + 55
Part B:
Subtract 55 from both sides
90.10 = 0.30x + 55
-55 -55

35.10 = 0.30x
Next, you need to isolate the variable so you must divide both sides by 0.30. You should get:
117 = x

Part C: (this part is a bit unclear, though I will try to answer it as best I can)
I found the number of text messages Vin sent in the month of October by creating an equation that outlined his bill and solving it.
