Answer:
C) 12
Step-by-step explanation:
Absolute value always means it is the positive version of the number
This switches -7 to 7 and 5 stays the same.
5 + 7 = 12
The absolute value returns the "positive version" of a number. This means that if the number is already positive, it does nothing. Otherwise, it gets rid of the negative sign.
So, you have
[tex]|5|=5,\quad |-7|=7[/tex]
and thus
[tex]|5|+|-7|=5+7=12[/tex]
