Question

match the scenarios to the equations.
the temperature was -16 degrees celsius and rose to 4 degrees celsius. what was the change in temperature?
the temperature was 4 degrees celsius and fell to -16 degrees celsius. what was the change in temperature?
$-16 + x = 4$
$4 + x = -16$

Explanation:

Step1: Analyze the first scenario

The initial temperature is -15 degrees Celsius, and it rose to 4 degrees Celsius. Let \( x \) be the change in temperature. The equation representing this is the initial temperature plus the change equals the final temperature, so \(-15 + x = 4\).

Step2: Analyze the second scenario

The initial temperature is 4 degrees Celsius, and it fell to -16 degrees Celsius. Let \( x \) be the change in temperature. The equation representing this is the initial temperature plus the change equals the final temperature, so \(4 + x = -16\).

Answer:

• "The temperature was -15 degrees Celsius and rose to 4 degrees Celsius. What was the change in temperature?" matches \(-15 + x = 4\)
• "The temperature was 4 degrees Celsius and fell to -16 degrees Celsius. What was the change in temperature?" matches \(4 + x = -16\)
