Question

на клумбе возле школы расли разные цветы. георгинов и хризантем было 12 кустов, хризантем и пионов - 9 кустов, пионов и георгинов было 11 кустов. сколько цветов каждого вида росло на клумбе

Answer 1

если мы посчитаем георгины и хризантемы, хризантемы и пионы, пионы и георгины то получим 12+9+11 кустов=30 кустов, но при этом мы считали каждый куст дважды, значит всех кустов 30:2=15 кустов

 

1) 12+9+11=32 кустов - удвоенное количевство всех кустов

2) 32:2=16 кустов - всего кустов

3) 16-12=4 куста пионов

4) 16-9=7 кустов георгин

5) 16-11=5 кустов хризантем

ответ 4 куста пионов, 7 кустов георгин, 5 кустов хризантем

 

Answer 2

Flower Bed Composition

The flower bed near the school contained different types of flowers, including dahlias, chrysanthemums, and peonies. The number of bushes for each type of flower is given as follows:

- Dahlias and chrysanthemums: 12 bushes - Chrysanthemums and peonies: 9 bushes - Peonies and dahlias: 11 bushes

To determine the number of each type of flower, we can solve this system of equations.

Let's denote: - The number of dahlias as D - The number of chrysanthemums as C - The number of peonies as P

We have the following equations: 1. D + C = 12 (Equation 1) 2. C + P = 9 (Equation 2) 3. P + D = 11 (Equation 3)

To solve for the number of each type of flower, we can use a method such as substitution or elimination to find the values of D, C, and P.

Solution

Using the given equations, we can solve for the number of each type of flower:

From Equation 1: D = 12 - C (Equation 4)

Substitute Equation 4 into Equation 3: (12 - C) + P = 11 P = 11 - 12 + C P = C - 1 (Equation 5)

Substitute Equation 4 into Equation 2: C + (11 - C) = 9 11 = 9 + C C = 2 (Equation 6)

Substitute Equation 6 into Equation 4: D = 12 - 2 D = 10 (Equation 7)

Substitute Equation 6 into Equation 5: P = 2 - 1 P = 1 (Equation 8)

Conclusion

Based on the given information, the number of each type of flower in the flower bed near the school is as follows: - Dahlias: 10 bushes - Chrysanthemums: 2 bushes - Peonies: 1 bush
