Question

Гвозди из меди латуни не боятся воды. На строительство корабля пошло 3 840 медных и латунных гвоздей. Причём латунных гвоздей ушло на 980 больше, чем медных. Сколько медных гвоздей пошло на строительство корабля? сколько латунных?

Answer 1

Медные х, латунные (х+980)

х+(х+980)= 3840
2х = 3840 - 980
х = 1430  - медных
1430 + 980 = 2410 - латунных

Calculation of Copper and Brass Nails for Ship Construction

To determine the number of copper and brass nails used in the construction of the ship, we are given the following information:

- Total number of copper and brass nails used: 3,840 - The number of brass nails used is 980 more than the number of copper nails.

Let's denote the number of copper nails as x and the number of brass nails as y.

From the given information, we can set up the following equations:

1. The total number of nails used: x + y = 3,840. 2. The number of brass nails used is 980 more than the number of copper nails: y = x + 980.

To solve this system of equations, we can substitute the value of y from equation 2 into equation 1:

x + (x + 980) = 3,840.

Simplifying the equation:

2x + 980 = 3,840.

Subtracting 980 from both sides:

2x = 2,860.

Dividing both sides by 2:

x = 1,430.

Therefore, the number of copper nails used in the construction of the ship is 1,430.

To find the number of brass nails, we can substitute the value of x into equation 2:

y = 1,430 + 980.

Simplifying the equation:

y = 2,410.

Therefore, the number of brass nails used in the construction of the ship is 2,410.

In summary, the ship was constructed using 1,430 copper nails and 2,410 brass nails.

Please note that the above calculations are based on the given information and may vary depending on the specific context or additional details.
