I don’t understand 12 and 13 at all pls help me out

Step-by-step explanation:

|54|

Solve for absolute value.

Apply rule : |a| = a

|54| = 54

-|-7.6|

Apply rule :  |-a| = a

-|-7.6| = -7.6

12: 54 and 13: -7.6

Step-by-step explanation:

The absolute value of a number is basically the distance it is from 0. For example, |1| = 1. There is a "rule" for absolute value, if a number x ≥ 0, then |x| = x but if x < 0, then |x| = -x. This is because absolute value is always positive, and if a number is negative, all you have to do to make it positive is multiply it by -1. Therefore, the answer for 12 is 54 since x > 0 in this case. To find the answer to 13, we know that |-7.6| = -(-7.6) = 7.6. -(7.6) = -7.6.

126 maybe. sorry
