Using the properties of inequalities
if you add −5, to both sides of the inequality 18>−7.
the inequality is 13 > -12
Do that with all of them
if you add 2.7, to both sides of the inequality 18>−7. the inequality is 20.7 > -4.3
if you add 7, to both sides of the inequality 18>−7. the inequality is 25 > 0
Hope this helps! Also I know its right bc RSM-Viki
