Answer 1

320-190=130кг було капусти
170-130=40кг було моркви
Відповідь:40 кг моркви і 130 кг капусти було у кухарки.

Answer 2

I can help you with your math problem. Let x be the weight of carrots, y be the weight of potatoes, and z be the weight of cabbage. Then we have the following system of equations:

$$ \begin{cases} x + y + z = 320 \\ y + x = 190 \\ x + z = 170 \end{cases} $$

To solve this system, we can subtract the second equation from the first one to get:

$$ z - y = 130 $$

Then we can add this equation to the third one to get:

$$ 2z = 300 $$

Dividing by 2, we get:

$$ z = 150 $$

This means that the cook had 150 kg of cabbage. To find the weight of carrots, we can substitute z into the third equation and get:

$$ x + 150 = 170 $$

Subtracting 150 from both sides, we get:

$$ x = 20 $$

This means that the cook had 20 kg of carrots. To find the weight of potatoes, we can substitute x into the second equation and get:

$$ y + 20 = 190 $$

Subtracting 20 from both sides, we get:

$$ y = 170 $$

This means that the cook had 170 kg of potatoes. Therefore, the answer is:

- The cook had 20 kg of carrots. - The cook had 170 kg of potatoes. - The cook had 150 kg of cabbage.
