Answer:
first box: F, second box: 25
Step-by-step explanation:
We are substituting "25" for "C" because the problem says to convert 25 degrees Celsius to (unknown) Fahrenheit
5/9(F - 32) = 25
I would then multiply both sides of the equation by 9 to get rid of the fraction, giving:
5(F -32) = 225
then divide both sides by 5
F - 32 = 45
then add 32 to both sides
F = 77
