(01.02 HC)Andrew is showing his work in simplifying (−5.7 + 2.2) − 1.1.

Step 1: (2.2 − 5.7) − 1.1
Step 2: 2.2 − (5.7 + 1.1)
Step 3: 2.2 − (6.8)
Step 4: −4.6

Which statement is true?
1. In step one andrew used the commutative property
2. in step 2 andrew used distributive property
3. in step 3 andrew used the associative property
4. In step 4 andrews answer is incorrect


  1. Answer: A
    Step-by-step explanation:
    Let’s fact check all the answer choices:
    A. He used the commutative property
    Well, the commutative property states that you can put the equation in any order and the result doesn’t change. In step1, andrew makes the equation  -5.7+2.2 into 2.2-5.7. Both of these equations equal -3.5, so yes, he used the commutative property.
    B.He used the distributive  property.
    We know this is wrong because the distributive property involves multiplication. An Example of an equation that involves the distributive  property is 3(2+1), or 3x(2+1).
    C. He used the associative property.
    This is wrong because the associative  property involves grouping the equation into different parentheses , which doesn’t happen.
    D.  The answer is incorrect
    Using a calculator , we know this is wrong.
    Hope this helps :)) Also if i could have brainliest id really appreciate it 😀
