Answer:
4°
Step-by-step explanation:
Add all the temperatures together and then divide by 7, since there are 7 days.
20+14+9+8-8-11-4=28
28/7=4
For the regular sequence 1, 2, 3, ...,

, then sum is

If we multiply each number by 7 (7, 14, 21, ...), then the sum is

and if we add 1 to each number (8, 15, 22, ...) then the sum is

We have

terms, so the sum is:




It is in the ones and tens digit i think thats the answer
So, the formula is C=5/9(F-32)
You would substitute the 50C for C:
50 = 5/9 (F - 32)
Divide both sides by 5/9 (or multiply by the reciprocal)
90 = F - 32
Add the 32 to both sides:
122 = F
So, 50C = 122F
