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

m + 2.1 > n + 2.1

m - (-4) > n )

m + 3 > n - 3

16.5 + m > 16.5 + n

m > n + 1/2

9 + m > 6 + n
will give a rank if can be answered in 5 min

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
