Answer:
The answer is -1200 +3(60)
Step-by-step explanation:
If the submarine is 1200 feet below sea level, that means that the submarine's level is -1200. If you rise by 60 in a 3 hour period, you rise by 60 every 3 hours. So if your rising by 60 feet, 60 is not a negative, and the equation would be -1200+3(60). Hope this helped! :D
Somebody else had asked this question and they said it was 35 so your best bet is to go with 35
It's the first one you can just add or multiply the expressions to get the answer

t=-13
We now know the temperature 6 hours ago was -13
