The high temperature on a day was 28º F. The low temperature for the same day was −4º F. What was the difference between the high and the low temperature?

28º F - (-4º F)

28 º F + 4 º F = 32º F difference

Which inequality can be used to find the number of hours, x, after which the temperature will measure below -3°C?

thank you

The temperature in Toronto at noon during a winter day measured 4°C.

To find the difference between the high and low temperatures, we need to subtract the low temperature from the high temperature.

High temperature: 28º F
Low temperature: -4º F

To subtract a negative number, we can add its absolute value:

Absolute value of -4º F = 4º F

Now, we can subtract the low temperature from the high temperature:

28º F - 4º F = 24º F

Therefore, the difference between the high and low temperatures is 24º F.
