If m > n, which inequalities must be true? Check all that apply.

m + 2.1 > n + 2.1

m - (-4) > n - (-4)

m + 3 > n - 3

16.5 + m > 16.5 + n

m > n + 1/2

9 + m > 6 + n

Step-by-step explanation:

m > n add 2.1 to both sides

m + 2.1 > n + 2.1 TRUE

m > n subtract (-4) from both sides

m - (-4) > n - (-4) TRUE

m > n add 16.5 to both sides

16.5 + m > 16.5 + n TRUE

m > n → 3 + m > n logic

3 + m > n add 6 to both sides

9 + m > 6 + n TRUE

It's A B and D, the brainliest is incorrect.
