Question

1. the temperature was 13°f and then dropped 5 degrees. what was the final temperature? 6. the temperature was -13°f and then dropped 5 degrees. what was the final temperature? 7. the temperature was -13°f and then rose to 5°f. what was the change in temperature? explain your thinking. 8. a swimmer was 8 feet underwater. then he swam 3 feet deeper. hikaru wrote the expression -8 - 3. charlie wrote the expression -8 + (-3). explain why both hikaru and charlie are correct.

Explanation:

Problem 5:

Step1: Identify initial and change

Initial temperature: \( 13^\circ\text{F} \), drop (decrease) by \( 5^\circ\text{F} \).

Step2: Calculate final temperature

Final temperature = Initial - Drop = \( 13 - 5 \)
\( 13 - 5 = 8 \)

Step1: Identify initial and change

Initial temperature: \( -13^\circ\text{F} \), drop (decrease) by \( 5^\circ\text{F} \).

Step2: Calculate final temperature

Final temperature = Initial - Drop = \( -13 - 5 \)
\( -13 - 5 = -18 \)

Step1: Identify initial and final temp

Initial: \( -13^\circ\text{F} \), Final: \( 5^\circ\text{F} \).

Step2: Calculate temperature change

Change = Final - Initial = \( 5 - (-13) \)
\( 5 - (-13) = 5 + 13 = 18 \)

Answer:

The final temperature is \( 8^\circ\text{F} \).
