the current temperature is - 7 degrees Celsius. The high temperature yesterday with as many degrees above 0 degrees Celsius as the current temperature is below zero degrees Celsius. Which expression can be used to find the number of degrees between the current temperature and yesterday's high temperature?
A. 0-7
B.-7+7
C.7+0
D.7+7
D 7+7
The answer Is D.
the correct answer is d
Ratio
To find the number of degrees between the current temperature and yesterday's high temperature, we need to calculate the absolute difference between the two temperatures.
The current temperature is -7 degrees Celsius, and yesterday's high temperature is as many degrees above 0 degrees Celsius as the current temperature is below zero degrees Celsius. In other words, yesterday's high temperature is the same number of degrees above 0 degrees Celsius as the current temperature is below zero degrees Celsius.
Therefore, the expression that can be used to find the number of degrees between the current temperature and yesterday's high temperature is:
|0 - (-7)|
Simplifying, we have:
|0 + 7|
Which is equal to 7.
So, the correct expression is:
D. 7 + 7.
