Question

Помогите пожалуйста! Урожайность малины у двух дачников одинаковая. Они собирали вместе 490 кг. Какова урожайность малины г/куст, если у одного 400 кустов, а у другого 300? Пусть x- урожайность малины с куста.

Answer 1

Х - урожайность малины с куста
490 кг=490000 г
400х+300х=490000
700х=490000
х=490000:700
х=700 (г/куст)
Ответ: урожайность малины 700 г с 1 куста

Answer 2

Calculating Raspberry Yield per Bush

To calculate the raspberry yield per bush, we can use the following approach:

Let's assume the yield per bush for the first gardener is x kg and for the second gardener is y kg. We are given that the first gardener has 400 bushes and the second gardener has 300 bushes, and together they harvested 490 kg of raspberries.

We can set up the following equations based on the given information: 1. 400x + 300y = 490 (total yield equation) 2. x + y = 1 (as we are finding the yield per bush, the total yield divided by the total number of bushes should be 1)

We can solve these equations to find the yield per bush for each gardener.

Solving the Equations

Let's solve the equations to find the values of x and y.

From the second equation, we can express y in terms of x as y = 1 - x.

Substituting this into the first equation: 400x + 300(1 - x) = 490 400x + 300 - 300x = 490 100x = 190 x = 1.9

So, the yield per bush for the first gardener is 1.9 kg.

Substituting x back into y = 1 - x: y = 1 - 1.9 y = -0.9

This negative value for y is not meaningful in this context, so we should re-evaluate the given information and the calculations.

Recalculating the Yield

It seems there might be an issue with the given information or the calculations. It's important to ensure that the numbers and equations are accurate to find a meaningful solution.
