Question

С одной гряды собрали 12 мешков моркови,а с другой - 8 мешков.Масса всей собранной моркови 960 кг.Найди массу моркови,собранной каждой гряды в отдельности

Answer 1

12+8=20 мешков - 960кг
960/20=48 кг каждый мешок
12*48=576 кг - 1 грядка
8*48=384 кг - 2 грядка!

Answer 2

Calculating the Carrot Harvest

To find the mass of carrots harvested from each row, we can use a system of equations. Let's denote the mass of carrots harvested from the first row as x and from the second row as y. We know that the total mass of carrots harvested is 960 kg, and the number of bags harvested from the first row is 12, while from the second row it is 8.

We can set up the following system of equations: 1. x + y = 960 (total mass of carrots harvested) 2. 12x + 8y = 960 (number of bags harvested)

Solving the System of Equations

We can solve this system of equations to find the mass of carrots harvested from each row.

First, let's express y in terms of x from the second equation: y = (960 - 12x) / 8

Substitute this value of y into the first equation: x + (960 - 12x) / 8 = 960

Solving for x: 8x + 960 - 12x = 7680 -4x = 7680 - 960 -4x = 6720 x = 6720 / -4 x = -1680

Now, let's find the value of y: y = (960 - 12*(-1680)) / 8 y = (960 + 20160) / 8 y = 21120 / 8 y = 2640

Answer:

The mass of carrots harvested from the first row is 1680 kg, and from the second row is 2640 kg.
