On a given morning, the temperature was 71℉. The temperature dropped 5℉ and then rose 8℉. How much does the temperature need to rise or fall to return to the initial temperature of 71℉?

Answer 1

The temperature dropped 5℉ and then rose 8℉, so it changed by 5℉ - 8℉ = -3℉.
To return to the initial temperature of 71℉, the temperature needs to rise or fall 3℉. Answer: \boxed{3}.

Answer 2

THATS WRONG

Answer 3

Apologies for the incorrect response. Let's calculate it correctly:

The temperature dropped by 5℉ and then rose by 8℉. When we add these changes together, we have a net increase of 8℉ - 5℉ = 3℉.

Since we want to return to the initial temperature of 71℉, we need to reverse this net increase by decreasing the temperature by 3℉. Therefore, the temperature needs to fall by 3℉. Answer: \boxed{3}.

Answer 4

Determine which of these illustrates two quantities that combine to make 0.

Answer 5

To illustrate two quantities that combine to make 0, we are looking for a pair of numbers where one is the opposite of the other.

For example:
-2 + 2 = 0
10 + (-10) = 0
3/4 + (-3/4) = 0

So any pair of numbers where one is the opposite of the other will combine to make 0.
