At 9:00 am, the temperature at an Arctic observatory was -12 ∘ F. By 5:00 pm, the temperature had risen 5 degrees. Over the next three hours, the temperature had dropped 2 degrees.
What was the temperature at 8:00 pm?
The answer is -5 degrees because -12+5=-7 then subtract 2 from -7 and you get -5 Emory Bell :)
"I'm Smart" Is right thank you. :)
and oobleck is correct 2 tysm to both of ya
-12 + 5 - 2 = ___
Thanks
To find the temperature at 8:00 pm, we need to determine the change in temperature from 5:00 pm to 8:00 pm.
Initially, at 9:00 am, the temperature was -12 °F.
From 9:00 am to 5:00 pm, the temperature rose by 5 degrees, so at 5:00 pm it was -12 + 5 = -7 °F.
Next, we know that over the next three hours, from 5:00 pm to 8:00 pm, the temperature dropped by 2 degrees. Therefore, at 8:00 pm, the temperature was -7 - 2 = -9 °F.
So, the temperature at 8:00 pm was -9 °F.
