Question 26259
so basically the question is asking you to input the values(10, 0, 15, and 100) in the formula F=(9/5)c+32 where the values = c. 
I'll give you an example:
Lets pick one value, say 0 for instance. F=(9/5)(0)+32
f=32. that means that when it is 0 celsius, it is 32 degrees fahrenheit.
I'll do another example--10 F=(9/5)(10)+32 ---> F=18+32 ---> F=50
Now you know how to do it why don't you try the other values (15 and 100.)
I hope this helps
