João and Maria are playing a game in which they need to balance the scale. They found out they can use sandbags to make both sides of the scale have the same weight. If João puts 7 sandbags on one side and 9 on the other, the scale is balanced. But if he puts 8 sandbags on one side, then Maria needs to put 3 fewer sandbags on the other side to balance it. It can be done differently: if he puts 6 sandbags on one side, Maria needs to put 3 fewer on the other side. Think of a number that, when added to 6, gives the same result as adding 8 with 3. Write in two different ways how João and Maria can place the sandbags to balance the scale.Answer sheet:

In a civil engineering project, an architect needs to divide a rectangular plot of land into two equal parts for the construction of two semi-detached houses. The coordinates of the vertices of the land on the Cartesian plane are A(0, 0), B(30, 0), C(30, 20), and D(0, 20). Using concepts of analytic geometry, determine the coordinates of the point that represents the midpoint of side CD of the land, which will be the dividing point between the two new properties. Then, verify if the obtained midpoint point is indeed on segment CD, ensuring the accuracy of the project. Explain the reasoning used to determine the coordinates and to verify the positioning of the midpoint on the land.
