Consider, pls, this option:
1. formula for conversion:

2. according to the formula:
C=(-31-32)*5/9=(-7)*5=-35°
Answer: -35°C.
3/4 = .75
4/7 = .57
the answer is : 3/4 > 4/7
Given your ordered pair you would assume a = 5, b = 2
Set up both equations
5 + 2 = 7
7 = 7 (the numbers are equal so this correct)
2(5) - 8 = 2
10 - 8 = 2
2 = 2 (the numbers are equal so this is also correct)
Because both equations work with the ordered pair they <em>are</em><span> the solution of the given system.</span>
