Answer:

$(a)\ m+ 2.1 > n + 2.1$

$(b).\ m - (-4) > n - (-4)$

$(c)\ 9 +m> 6 + n$

Explanation:

Given

m > n

Required

Select true inequalities

$(a)\ m+ 2.1 > n + 2.1$

Subtract 2.1 from both sides

m > n

This is true

$(b).\ m - (-4) > n - (-4)$

Open brackets

m + 4 > n + 4

Subtract 4 from both sides

m > n

$(c)\ 9 +m> 6 + n$

m> -9+6 + n

m> n-3

This is also true
