|–9.23 – 1.79| – |–7.34 – 2.57| (25 points)
galina1969 [7]

Answer:

1.11

Step-by-step explanation:

First, you ignore the absolute value sign and subtract normally: –9.23 – 1.79 = -11.02, –7.34 – 2.57 = -9.91.  Then now you add the absolute value to the numbers: |-11.02| - |-9.91| = 11.02 - 9.91 = 1.11.
