Answer:
The right options are A and D.
Step-by-step explanation:
1. Option A.
The action is:Add 3 to both sides. This means that we need to do the following operation:
x - 3 = 12
∴ x - 3 + 3 = 12 + 3
∴ x = 15
So, the solution of this problem is x = 15.
2. Option D.
The property is:Addition property of equality. This is the property we are chosen because we need to isolate the variable x. To do that, we need to add a number of each side of the equation to find our goal and this property allows us to get our goal.
45, right? 300 plus the 15 percent which is .15, so we multiply that to 300 and we get 45. So in total they paid 345. Was Jerry Tom's snack?
