яблок 3а

апельсинов 3а-b

всего а + 3a+(3a-b)

Answer 3

Problem Analysis

We are given the following information: - The number of pears is a. - The number of apples is 3 times the number of pears, so it is 3a. - The number of oranges is b less than the number of apples, so it is 3a - b.

We need to find the total number of pears, apples, and oranges in the vase.

Solution

To find the total number of fruits in the vase, we need to add the number of pears, apples, and oranges together.

Let's calculate the total:

Total = Number of pears + Number of apples + Number of oranges

Total = a + 3a + (3a - b)

Total = 7a - b

Therefore, the total number of fruits in the vase is 7a - b.

Now, we need to find the values of a and b to calculate the total number of fruits.

Calculation of a and b

Unfortunately, the provided search results do not directly provide the values of a and b. However, we can use the given information to set up a system of equations and solve for a and b.

From the given information, we have the following equations:

Equation 1: Number of apples = 3 times the number of pears 3a = a

Equation 2: Number of oranges = Number of apples - b 3a - b = a

Simplifying Equation 2, we get: 2a - b = 0

Now, we have a system of equations: 3a = a 2a - b = 0

Solving this system of equations will give us the values of a and b, which we can then substitute into the equation for the total number of fruits.

Unfortunately, without the exact values of a and b, we cannot determine the total number of fruits in the vase.
