At 7 pm, the temperature was 66*F

Temp = 78 - 3x where x = number of hours
78 - 3(7-3)
78 - 12 = 66

Can anyone pls answer this! it's really urgent! ​
stich3 [128]

Answer:

The answer is C

Step-by-step explanation:

You need to find a common denominator and in this case its 20. SO you change 3/4ths to 15/20 and 4/5ths to 16/20ths and 19/20 stays the same. Then you cancel out the 20 because its all the same number (I think) and you have your answer.
