m + 9 = 2 Therefore, m = 2 - 9 m = -7
-3
the sum of m and 9 is 9+m
31
If m - 3 = 9, m = 12
M - 9 = 11 so M - 11 = 9 then, you complete this fact family by putting in the 2 addition problems: 9 + 11 = M 11 + 9 = M then, you solve the problem: 11 + 9 = 20 therefore M = 20
9 m x 2.5 m = 22.5 m2.
9 sq m
m = 31m + 9 = 1(3) + 9 = 3 + 9 = 12
9 + 9 + 4.5 + 4.5 = 27 m
m/(-4) = 9m = 9 x (-4)m = -36
m+9
