Step 1: (5.2 − 4.5) − 5.5 + 4.8 step 2: 5.2 + (− 4.5 − 5.5) + 4.8 (identity property) step 3: 5.2 − 10 + 4.8 step 4: 5.2 + 4.8 − 10 (commutative property) step 5: 10 − 10 = 0

maya is showing her work in simplifying (5.2 − 4.5) − 5.5 + 4.8. identify any error in her work or reasoning.

The answer is "a"radius = 12.7 unitsdiameter = radius × 212.7 units × 2 = 25.4 units

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
