Question

If the temperature is -7.3 degrees Celsius, and the temperature decreases another 1.3 degrees Celsius. Write two (2) equations for the information provided above. What is the final temperature for that day?

a) T = -7.3 - 1.3
b) T = -7.3 + 1.3
c) T = -7.3 * 1.3
d) T = -7.3 / 1.3

Answer 1

The final temperature after a decrease of 1.3 degrees Celsius from -7.3 degrees Celsius is -8.6 degrees Celsius, represented by the equation T = -7.3 - 1.3. The correct option is a.

Step-by-step explanation:

The student's question pertains to calculating the final temperature after a decrease in degrees Celsius. To represent the scenario with equations, we use subtraction for a decrease in temperature.

The correct equation from the options provided is:

a) T = -7.3 - 1.3

Using this equation, we can find the final temperature:

T = -7.3 - 1.3 = -8.6 degrees Celsius

Therefore, the final temperature for that day is -8.6 degrees Celsius. Option b), c), and d) do not correctly represent the decrease in temperature. The correct option is a.
