I think it would be D. because when you switch the number to the other side you need to switch it from positive/negative in this case it would change to a positive because it's negative and you would keep the sign the way as it is. Hope I helped! :)
First, let's subtract 3 on both sides to have the variables on a side and the numbers on another side: 3 - 2a > 7 3 - 2a - 3 > 7 - 3 - 2a > 4
Let's divide both sides by -2 to have a on side and its value on the other side: -2a > 4 (-2a)/(-2) > (4/-2) a < -2 (In a case of an inequality, we change the sign when we divide by a negative number to its opposite).
There is an equal odd of rolling any of the parts of a dice. So the ratio per side would be 1:6, only because every side has the same probability to be shown.
