на 4 больше и на 4 меньше

Answer 2

Calculating the Number of Coal Wagons in the Composition

To calculate the number of coal wagons in the composition, we can use the information provided in the question. Let's break it down step by step.

Given: - Number of tank wagons: 15 - Number of wagons with wood: 7 - Number of wagons with coal is as much more than wagons with wood as it is less than tank wagons

Let's denote: - Number of coal wagons as C - Number of wood wagons as W - Number of tank wagons as T

We can express the given information as equations: 1. C = W + (T - W) - The number of coal wagons is as much more than wagons with wood as it is less than tank wagons.

2. T = 15 - The number of tank wagons is 15.

3. W = 7 - The number of wagons with wood is 7.

Now, let's solve for C using the given information.

Calculations

Using the equation C = W + (T - W), and substituting the given values: C = 7 + (15 - 7) C = 7 + 8 C = 15

So, there are 15 coal wagons in the composition.

Therefore, in this composition, there are 15 wagons with coal.
