Answer 1

The real-world problem that could be solved with the sum −22 + 9 is:

The temperature was −22°F yesterday. Today the temperature is 9°F. How much warmer is it today compared with yesterday?

This problem involves comparing two temperatures with one being negative, which directly utilizes the calculation of -22 + 9 to determine how much warmer it is today.

Question Solve the following problem: It was −8° F this morning, but the temperature has gone up 11° over the course of the day. What is the temperature now?(1 point) Responses 3°F 3 degrees F 19°F 19 degrees F −3°F negative 3 degrees F 11°F 11 degrees F Skip to navigation

Answer 3

To find the current temperature, we need to add the increase in temperature to the initial temperature:

Initial temperature: \(-8°F\)
Increase in temperature: \(11°F\)

Now, we perform the calculation:

\[ -8 + 11 = 3 \]

The current temperature is \(3°F\).

So, the correct response is 3°F or 3 degrees F.

Answer 5

To find the current temperature after the increase, we start with the morning temperature of \(-8°F\) and add the increase of \(11°F\):

\[ -8 + 11 = 3 \]

Therefore, the temperature now is \(3°F\).

The correct response is 3°F or 3 degrees F.

Answer 6

There are some areas of land on Earth that are below sea level. Imagine you are at the Dead Sea in Africa, which has an elevation of about −1,410 feet (1,410 feet below sea level). You then climb up 125 feet. What is your new elevation?(1 point) Responses −1,285 feet negative 1,285 feet −1,535 feet negative 1,535 feet 1,285 feet 1,285 feet −1,335 feet

Answer 7

To determine your new elevation after climbing up 125 feet from an elevation of -1,410 feet, you can perform the following calculation:

Initial elevation: \(-1,410\) feet
Increase in elevation: \(125\) feet

Now, add the increase to the initial elevation:

\[ -1,410 + 125 = -1,285 \]

Your new elevation at the Dead Sea after climbing 125 feet is \(-1,285\) feet.

The correct response is −1,285 feet or negative 1,285 feet.

Answer 8

Reem owes her friend $15.25. Reem works after school and earns $43.78. After paying her friend back, how much money does she have?(1 point)

−$59.03

Answer 9

To find out how much money Reem has after paying her friend back, we can follow these steps:

1. Start with the amount Reem earns: $43.78.
2. Subtract the amount she owes her friend: $15.25.

Now, perform the calculation:

\[ 43.78 - 15.25 = 28.53 \]

After paying her friend back, Reem has $28.53.

The correct response is $28.53.
