Question

The temperature of a city changed by -24 degrees Celsius over a 6-week period. The temperature changed by the same amount each week.

Write an expression to show the average change in the temperature of the city each week.

A) -4°C
B) -24°C
C) -4°C/week
D) -24°C/6 weeks

Answer 1

The expression to show the average change in temperature of the city each week is -4°C/week.

Step-by-step explanation:

The average change in temperature of the city each week can be calculated by dividing the total change in temperature over the 6-week period by the number of weeks.

Let's assume the average change in temperature each week is represented by 'x' degrees Celsius. We know that the total change in temperature is -24 degrees Celsius over 6 weeks. So, we can set up the equation:

-24 degrees Celsius = x degrees Celsius/week * 6 weeks

To solve for 'x', we can divide both sides of the equation by 6:

x = -24 degrees Celsius / 6 weeks = -4 degrees Celsius/week.

Therefore, the expression to show the average change in temperature of the city each week is -4°C/week.
