Question

Второклассники во время перемены играли в мяч и считали,сколько раз каждый из них сможет отбить мяч ногой,прежде чем мяч упадёт на землю. Учитывая приведенные ниже условия,посчитай,сколько раз каждый из ребят отбил мяч ногой. 1.Миша отбил мяч на 8 раз меньше,чем Коля,который отбил мяч (21-8+4)раз. 2.Саша и Вася вместе отбили мяч 37 раз. 3.Рома отбил мяч на 8 раз больше,чем Саша. 4.Разница между количеством отбитых мячей Миши и Саши составляет всего 3 мяча. 5.Коля отбил мяч на 5раз больше,чем Саша.

Answer 1

1 Миша отбил 9 раз
2 Саша 6 или 12 и Вася 31 или 25
3 Рома 14 или 20
5 Коля 11 или 25

Answer 2

Коля 21-8+4=17
Миша 17-8=9
Саша 17-5=12
Рома 12+8=20
Вася 37-12=25

Answer 3

To solve this problem, let's assign variables to represent the number of times each person kicked the ball. Let's use the following variables: - M for Misha - K for Kolya - S for Sasha - V for Vasya - R for Roma

Now let's analyze the given conditions and equations:

1. Misha kicked the ball 8 times less than Kolya, who kicked the ball 21-8+4 = 17 times. - Equation 1: M = K - 8 - Substituting the value of K, we get M = 17 - 8 = 9

2. Sasha and Vasya together kicked the ball 37 times. - Equation 2: S + V = 37

3. Roma kicked the ball 8 times more than Sasha. - Equation 3: R = S + 8

4. The difference between the number of balls kicked by Misha and Sasha is 3. - Equation 4: M - S = 3

5. Kolya kicked the ball 5 times more than Sasha. - Equation 5: K = S + 5

Now we have a system of equations. Let's solve it to find the values of M, K, S, V, and R.

Solving the System of Equations:

From Equation 1, we know that M = K - 8. Substituting this into Equation 4, we get (K - 8) - S = 3. Simplifying, we have K - S = 11. This will be Equation 6.

Adding Equation 2 (S + V = 37) and Equation 3 (R = S + 8), we get S + V + R = 37 + (S + 8). Simplifying, we have V + R = 45 - S. This will be Equation 7.

Adding Equation 5 (K = S + 5) and Equation 6 (K - S = 11), we get K + K = (S + 5) + (K - S). Simplifying, we have 2K = 16. Therefore, K = 8. This will be Equation 8.

Now, let's substitute the value of K into Equation 5 to find the value of S. S = K - 5 = 8 - 5 = 3. This will be Equation 9.

Substituting the values of K and S into Equation 6, we get 8 - 3 = 11. Therefore, Equation 6 is satisfied.

Substituting the values of S and K into Equation 2, we get 3 + V = 37. Therefore, V = 37 - 3 = 34. This will be Equation 10.

Substituting the value of S into Equation 3, we get R = 3 + 8 = 11. This will be Equation 11.

Calculating the Number of Times Each Person Kicked the Ball:

From the above calculations, we have found the following values: - M = 9 - K = 8 - S = 3 - V = 34 - R = 11

Therefore, each person kicked the ball the following number of times: - Misha (M): 9 times - Kolya (K): 8 times - Sasha (S): 3 times - Vasya (V): 34 times - Roma (R): 11 times
