Yes, notice for every 10 degrees in Celsius you have 18 degrees Fahrenheit.
32 is the freezing point of water in F, and 0 is the freezing point of water in C.
So it is starting at freezing point, every time you add 10 in C you also add 18 to F.
They show the same temperature just on different scales.
2x + 3y = 40
+
-2x + 2y = 20
___________ Adding both equations
0x + 5y = 60
____________
5y = 60
y = 60/5 = 12
y = 12.
Since we have gotten y =12, and the only option with that is option D.
So we don't have to solve for x.
<span>The answer is D.</span>
Here, v - w would be (6-1, 3-[-2]), or (5, 5).
I don't believe you need the word "result" here. At first I thought you'd meant "resultant." Here you're finding the "difference" v less w.
