Question

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

Answer 1

do you still need help on this wuestion?

Answer 2

so like a first step assume these terms inside parentheses

Answer 3

Step 1:
Solve the things inside of the parentheses

\( (−5.7 + 2.2) − 1.1\) \(−3.5−1.1\) \(−5.7 + 2.2=-3.5\)

Answer 4

Notice what Andrew did wrong was changed the `+` to a `−`.
