Answer 1

1) 900-670=230 кг 
2)900-586=314 кг 
3) 230+314=544кг
4)900-544=356кг
Відповідь: 356 кг моркви привезли у 1 магазин

Answer 2

Solution:

To solve this problem, we can use a system of equations to find the amount of carrots delivered to the first store.

Let's denote the amount of carrots delivered to the first store as x, to the second store as y, and to the third store as z.

We have the following information: 1. x + y = 586 (carrots delivered to the first and second stores) 2. x + z = 670 (carrots delivered to the first and third stores) 3. y + z = 900 (carrots delivered to the second and third stores)

We can solve this system of equations to find the value of x.

Calculation:

Subtracting equation 1 from equation 2, we get: z - y = 84 (equation 4)

Adding equation 1 and equation 2, we get: 2x + y + z = 1256 (equation 5)

Adding equation 3 and equation 4, we get: 2z = 984 z = 492 (equation 6)

Substituting the value of z into equation 3, we get: y + 492 = 900 y = 408 (equation 7)

Substituting the values of y and z into equation 5, we get: 2x + 408 + 492 = 1256 2x + 900 = 1256 2x = 356 x = 178

Answer:

So, the first store received 178 kg of carrots.
