Write two different equations that can be used to solve this problem: a low of -4 degrees is predicted for tomorrow. If the tempeture is now 8 degrees by how much must it change?

I will be happy to critique your thinking.

I don't know because if I use these

-4+-4 it gives me -8 not 8, and if I use this -4+4 it gives me 0, so I don't know, what do you think?

What is TEmperatureN0w-Temperaturetomorrow?

To find the change in temperature, we can subtract the current temperature from the predicted temperature for tomorrow. Let's use the variable "change" to represent the change in temperature.

Equation 1: change = predicted temperature - current temperature
In this case, the predicted temperature for tomorrow is -4 degrees, and the current temperature is 8 degrees. Plugging these values into the equation, we get:
change = -4 - 8
change = -12 degrees

So, the temperature must change by -12 degrees.

Equation 2: change = |predicted temperature - current temperature|
In this equation, the absolute value notation (| |) is used to ensure that the result is always positive. The result represents the magnitude of the change, regardless of whether it is an increase or a decrease.

Using this equation, we can calculate the change in temperature as follows:
change = |(-4) - 8|
change = |-12|
change = 12 degrees

So, the magnitude of the temperature change is 12 degrees.
