Question

Для оформления альпийской горки привезли 1 тонну и 400 кг гальки белого и темно серого цветов, причем белой гальки на 260 кг меньше, чем тем но серой. Сколько гальки каждого цвета было привезено

Answer 1

Пусть x это масса белой гальки, тогда x+260 масса серой гальки
Составим уравнение
X+X+260=1400
2x= 1400-260
2x=1140
X=570 кг масса белой гальки
570+260=830 кг масса серой гальки

Answer 2

1 т 400 кг = 1400 кг

Пусть X кг - серая галька
Тогда X - 260 кг - белая галька

Т.к. всего привезли 1400 кг, то составим и решим уравнение

x + x - 260 = 1400
2x = 1400 + 260
2x = 1660
x = 830 кг - серой гальки

830 - 260 = 570 кг - белой гальки

Ответ: 830 кг, 570 кг

Answer 3

Calculating the Amount of Gravel

To calculate the amount of gravel of each color, we can use the given information. Let's denote the amount of white gravel as W and the amount of dark gray gravel as D. We are given the following information:

1. The total amount of gravel is 1 ton and 400 kg, which is equivalent to 1400 kg. 2. The amount of white gravel is 260 kg less than the amount of dark gray gravel.

We can set up the following equations based on the given information:

- W + D = 1400 (total amount of gravel is 1400 kg) - W = D - 260 (amount of white gravel is 260 kg less than the amount of dark gray gravel)

Now, we can solve these equations to find the amounts of each color of gravel.

Solving for the Amount of Each Color

Substituting the second equation into the first equation, we get:

D - 260 + D = 1400

Simplifying the equation:

2D - 260 = 1400

2D = 1660

D = 830

Now that we have found the amount of dark gray gravel, we can find the amount of white gravel using the equation W = D - 260:

W = 830 - 260

W = 570

Conclusion

Therefore, the amount of white gravel is 570 kg and the amount of dark gray gravel is 830 kg.
