To find the sum of -5 and +2, we can simply add the two numbers together:

-5 + 2 = -3

Therefore, the sum of -5 and +2 is -3.

To find the difference between the average summer temperature and the average winter temperature, we simply subtract the winter temperature from the summer temperature:

61℉ - (-12℉)

When subtracting a negative number, we can change the operation to addition:

61℉ + 12℉ = 73℉

Therefore, the difference between the average summer temperature and the average winter temperature in Fairbanks, Alaska is 73℉.

To simplify the expression -851 - (-394), we can follow these steps:

1. Remove the double negatives by changing the subtraction of a negative to addition:
-851 + 394

2. Add the two numbers together:
-457

Therefore, the simplified expression -851 - (-394) is -457.

To find how many times farther Bertha's dive ended from the starting platform compared to Vernon's dive, we can calculate the ratio of their distances from the starting platform.

The distance of Bertha's dive from the starting platform: -30 m
The distance of Vernon's dive from the starting platform: -6 m

To find the ratio, we divide Bertha's distance by Vernon's distance:

-30 m / -6 m = 5

Therefore, the end of Bertha's dive is 5 times farther from the starting platform than the end of Vernon's dive. The correct answer is 5.

To find the product of (-5)(-3)(-3), we can simply multiply the three numbers together:

(-5)(-3)(-3) = (-5)(-9) = 45

Therefore, the product of (-5)(-3)(-3) is 45.

To find the quotient of 100 ÷ (-50), we divide 100 by -50:

100 ÷ (-50) = -2

Therefore, the quotient of 100 ÷ (-50) is -2.

To find the temperature change per hour, we need to divide the total temperature drop by the number of hours:

Temperature change per hour = Total temperature drop / Number of hours

In this case, the total temperature drop is 42 degrees and the number of hours is 7. Therefore:

Temperature change per hour = 42℉ / 7 = 6℉

Therefore, the temperature changed by 6℉ per hour. The correct answer is -6℉.

To determine how much the temperature needs to rise or fall to return to the initial temperature of 71°F, we need to consider the net change in temperature.

The temperature dropped 5°F and then rose 8°F. Therefore, the net change in temperature is:

-5°F + 8°F = 3°F

Since the net change is 3°F, the temperature needs to fall by 3°F in order to return to the initial temperature of 71°F.

Therefore, the correct answer is "Fall 3F."

The statement that illustrates two quantities combining to make zero is:

Marty gets $10 for his allowance and then spends $10 at the movies.

In this scenario, Marty receiving $10 followed by spending $10 results in a net change of $0. Therefore, the combination of getting $10 and spending $10 makes zero.
