Answer 1

1. 21/3=7 в - съели с первой тарелки
2. 21-12=9 в -съели во второй тарелки
далее не могу сказать, т.к. не написано, сколько их было на тарелках

Answer 2

Calculating the Cherries on Each Plate

To solve this problem, we can use a system of equations based on the given information. Let's denote the number of cherries on the first plate as x, on the second plate as y, and on the third plate as z.

We are given the following information: 1. The number of cherries on the first plate is 3 times less than the number on the third plate. 2. The number of cherries on the second plate is 12 less than the number on the third plate. 3. The number of cherries on the third plate is 21.

Using this information, we can set up the following equations: - x = z/3 - y = z - 12 - z = 21

Now, let's solve for the number of cherries on each plate.

Solving for the Number of Cherries on Each Plate

Using the given equations, we can solve for the number of cherries on each plate: 1. From the third equation, z = 21. 2. Substituting z = 21 into the first equation, x = 21/3 = 7. 3. Substituting z = 21 into the second equation, y = 21 - 12 = 9.

So, the number of cherries on each plate is: - First plate (x): 7 cherries - Second plate (y): 9 cherries - Third plate (z): 21 cherries

Therefore, there are 7 cherries on the first plate, 9 cherries on the second plate, and 21 cherries on the third plate.
