Question

Для датского сада куплено 36 трёхколёсных и двухколёсных велосипедов.У этих велосипедов всего93 колеса Сколько двухколёсных и сколько двухколёсных?

Answer 1

2х+108-3х=93. -х+108=93.х=108-93.х=15 шт-двухколесных велосипедов. 36-х=36-15=21 шт- трехкодесных

Answer 2

Calculating the Number of Bicycles

To solve this problem, we can use a system of equations to represent the given information. Let's denote the number of three-wheeled bicycles as x and the number of two-wheeled bicycles as y. We are given two pieces of information: 1. The total number of bicycles is 36: x + y = 36 2. The total number of wheels is 93: 3x + 2y = 93

Solving the System of Equations

We can solve this system of equations to find the values of x and y.

First, let's express x in terms of y from the first equation: x = 36 - y

Now, substitute this expression for x into the second equation: 3(36 - y) + 2y = 93 108 - 3y + 2y = 93 108 - y = 93 -y = 93 - 108 -y = -15 y = 15

Now that we have found the value of y, we can find the value of x: x = 36 - 15 x = 21

Conclusion

So, there are 21 three-wheeled bicycles and 15 two-wheeled bicycles in the Danish garden.

This solution is based on the given information and the calculations performed.
