Question

five days on the number line. what is the change in temperature from wednesday to thursday? °c monday: -4°c thursday: -8°c tuesday: -11°c wednesday: -13°c friday: -18°c

Explanation:

Step1: Identify initial and final temperatures

Initial temperature on Wednesday is $- 13^{\circ}C$, final temperature on Thursday is $-8^{\circ}C$.

Step2: Calculate temperature change

Use the formula $\text{Change}=\text{Final}-\text{Initial}$, so $\text{Change}=-8 - (-13)$.
According to the rule of subtracting a negative number ($a-(-b)=a + b$), we have $-8-(-13)=-8 + 13$.
$-8+13 = 5$.

Answer:

$5$
