1/80 = 0.0125
1/5 = 0.2
0.0125-0.2 = -0.1875
-0.1875 = -3/16
Your Answer Is C) III Only.
A temperature increase of 5/9 degrees Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
One way we could check is by multiplying (f -32) by five degrees.
( f - 32 ) = 31
9 / 5 = 1.8
31 * 1.8 = 55.8
55.8 / 14^2 = 0.28
Now, let's check,
0.28 / 1.8 = 0.504
0.504 * 28.1232 = 55.8
Or it could be solved by keeping on adding. (That would be easier but I prefer multiplying.)

Answer:
2 and 4 I am pretty sure. hopeful that's correct.
For the first one, to find x, you are going to take that entire side which would equal to 180 and solve. 2x+20+55=180 would then go down to 2x+65=180 once you add the 20 and 55. Then subtract 65 to both sides and divide your final answer 115/2 which is x=57.5. For the second one it’s 4x-2+21=180, then you will subtract 2 from 21 and get 19. After you would subtract 19 by 180 and divide 4 by each side, getting x=40.25 as your final answer.
