The mean room temperature from Monday to Saturday is 25oC and the mean room temperature of Saturday and Sunday is 28oC. if the mean room temperature from Monday to Sunday is 26oC, find the room temperature on Saturday

24 °C

Step-by-step explanation:

Mean =

Given:  Mean room temperature from Monday to Saturday = 25°C

Sum of temperature from Monday to Saturday = 6 x  25°C   [Total 6 days from Monday to Saturday]

=  150°C

Mean room temperature of Saturday and Sunday = 28°C

Sum of temperature of Saturday and Sunday = 2 x28°C

=56 °C

Sum of temperature from Monday to Sunday = 7 x 26°C

= 182 °C

Room temperature on Saturday =  150°C  + 56 °C  - 182 °C

= 24 °C

Hence, the room temperature on Saturday = 24 °C

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
