Question

Как решить задачу .Водную поверх пруда украшают белые,голубые и тигровые кувшинки. Белых и голубых-33 кувшинки,голубых и тигровых-39 кувшинок,белых и тигровых-36 кувшинок. Сколько всего кувшинок разного вида?

Answer 1

1) 33+39+36=108 - удвоенная сумма всех кувшинок;
2) 108:2=54 - сумма всех кувшинок;
3) 54-33=21 - тигровые;
4) 36-21=15 - белые;
5) 33-15=18 - голубые.

Answer 2

Problem Analysis

To solve this problem, we need to determine the total number of different types of water lilies (кувшинки) in the pond. We are given the following information: - The number of white and blue water lilies is 33. - The number of blue and tiger water lilies is 39. - The number of white and tiger water lilies is 36.

Let's denote the number of white water lilies as W, the number of blue water lilies as B, and the number of tiger water lilies as T.

Solution

To find the total number of different types of water lilies, we need to determine the values of W, B, and T.

From the given information, we can form the following equations:

1. W + B = 33 (Equation 1) 2. B + T = 39 (Equation 2) 3. W + T = 36 (Equation 3)

To solve this system of equations, we can use a method called substitution or elimination.

Substitution Method

Let's solve the system of equations using the substitution method.

From Equation 1, we can express W in terms of B: W = 33 - B (Equation 4)

Substituting Equation 4 into Equations 2 and 3, we get: 33 - B + T = 39 (Equation 5) 33 - B + 36 - T = 39 (Equation 6)

Simplifying Equations 5 and 6, we have: -B + T = 6 (Equation 7) -B - T = 3 (Equation 8)

Adding Equations 7 and 8, we get: -2B = 9

Solving for B, we find: B = -4.5

Since the number of water lilies cannot be negative, there seems to be an error in the given information or the problem statement.

Unfortunately, without additional information or clarification, it is not possible to determine the exact number of different types of water lilies in the pond.
