ON FRIDAY THE TEMPERATURE REACHES A HIGH OF 21 DEGREES ABOVE 0, AND A LOW OF 4 DEGREES BELOW 0. WHAT IS THE DIFFERENCE BETWEEN THE HIGH AND LOW TEMPERATURES FOR FRIDAY?
put these two points on a number line
one is four to the left of zero and the other is 21 to the right of zero
so
the total distance between them is 21 + 4 = 25
or write
21 - (-4) = 21 + 4 = 25
Friday's high temperature was -1 Celsius. the low temperature was -5 Fahrenheit. what was the difference between the high and low temperatures
To find the difference between the high and low temperatures for Friday, we need to subtract the low temperature from the high temperature.
The high temperature is given as 21 degrees above 0, which means it is 21 degrees higher than 0. So the high temperature is 0 + 21 = 21 degrees.
The low temperature is given as 4 degrees below 0, which means it is 4 degrees lower than 0. So the low temperature is 0 - 4 = -4 degrees.
Now, we can calculate the difference between the high and low temperatures by subtracting the low temperature from the high temperature:
High temperature - Low temperature = 21 degrees - (-4 degrees)
= 21 + 4
= 25 degrees
Therefore, the difference between the high and low temperatures for Friday is 25 degrees.
