Your answer would be D) -3°F/hour
Look at it this way...
47°F at 7:20pm
46°F at 7:40pm
45°F at 8:00pm
44°F at 8:20pm
43°F at 8:40pm
The temperature is going down by 1°F every 20 minutes so...
-1°F/20 minutes
Obviously there's no answer choice that says that so you'd need to change the minutes into an hour...
So an hour is 60 minutes and 60/20 = 3
So if you do 3・-1
You get the answer... -3°F/hour

Answer:
36 ÷ 9= 4
Step-by-step explanation:
9 x 4= 36
The division equation for this is 36 ÷ 9= 4
Answer:
D) Undefined
Step-by-step explanation:

Answer:
Angle EFG = 104 degrees
Angle GFH = 76 degrees
Step-by-step explanation:
Angle EFG and Angle GFH are a linear pair, which means that they add up to 180 degrees.
Angle EFG = 4n + 20 and Angle GFH = 2n + 34, so 4n + 20 + 2n + 34 = 180.
We can then combine like terms, getting 6n + 54 = 180.
Then, we can subtract both sides by 54, getting 6n = 126.
Lastly, we can divide both sides by 6, getting n = 21.
EDIT - solve for EFG and GFH:
Angle EFG = 4n + 20 = 4(21) + 20 = 104 degrees
Angle GFH = 2n + 34 = 2(21) + 34 = 76 degrees
