1) m - 7 < 6
Add 7 to the both sides,
m - 7 + 7 < 6 + 7
m < 13
So, Option C is your answer for this part.
2) x+4.5 ≥ 5.5
Subtract 4.5 from both sides,
x ≥ 1
So, Option B is your answer for this part.
3) p +12 > 9
Subtract 12 from the both sides,
p > -3
So, Option D is your answer for this part.
4) x - 5 ≥ 9
So, Option A is your answer for this part
Hope this helps!
