C= 20 degrees Celsius
20 x 9/5 = 180/5
180 divided by 5 = 36 degrees celsius
Then you do 36 degrees celsius + 32 and you get 68.

Answer:
r = - 
Step-by-step explanation:
Given that r varies inversely as t , then the equation relating them is
r = 
← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = 
( multiply both sides by - 6 )
12 = k, thus
r = 
← equation of variation
when t = - 7, then
r = 
= -
