Question

A city’s record high temperature is 106°F and record low temperature is −17°F. How much warmer is the city’s record high temperature than the record low temperature? (1 point)
A. 123F
B. -123F
C. 89F
D. -89F

Answer 1

You have a score of −500 points in a game. After three rounds of answering your questions correctly, you have a score of 2,700 points. What is the change in score?

A. 2,200 points

B.3,200 points

C.1,700 points

D.2,700 points

Answer 2

A diver is 15 feet below sea level. The diver then swims up 15 feet to the surface. Which expression shows the correct sum?

A. (−15)+(−15)=0

B.(−15)+15=30

C.(−15)+15=0


D.(−15)+(−15)= -30

Answer 3

To find the difference between the high and low temperatures, we subtract the low temperature from the high temperature: 106°F - (-17°F) = 106°F + 17°F = 123°F.

Therefore, the city's record high temperature is 123°F warmer than the record low temperature.

The correct answer is A. 123°F.

Answer 4

To find the change in score, we subtract the initial score from the final score: 2,700 points - (-500 points) = 2,700 points + 500 points = 3,200 points.

Therefore, the change in score is 3,200 points.

The correct answer is B. 3,200 points.

Answer 5

The correct expression to represent the sum is (−15) + 15 = 0.

In this case, the diver starts at a depth of -15 feet below sea level and swims up 15 feet. The negative sign in front of the 15 indicates that the diver is moving in the positive direction (up) from a negative starting point. Adding -15 and +15 together cancels out the negative and positive values, resulting in 0.

Therefore, the correct answer is C. (−15) + 15 = 0.
