Answer 1

2500-700=1800
5ч+1ч=6частей
1800/6=300
1 часть (шапка) стоила 300
5 частей (свитер) стоил 1500

Answer 2

X-свитер=700; y-свитер; z-шапкаж
x+y+z=2500; y=5z; x=2500;
700+5z+z=2500;
6z=1800; z=300 - шапка;
y=5z=1500 - свитер.

Answer 3

Solution:

Let's solve this step by step.

1. Cost of Boots, Hat, and Sweater: - The boots cost 700 rubles. - The sweater is 5 times more expensive than the hat. - The total cost of all three items is 2500 rubles.

2. Calculating the Cost of the Sweater: - Let's assume the cost of the hat is x rubles. - The sweater is 5 times more expensive than the hat, so its cost is 5x rubles. - The total cost of the three items is 2500 rubles, so we can form the equation: 700 (cost of boots) + x (cost of hat) + 5x (cost of sweater) = 2500.

3. Solving for the Cost of the Sweater: - We can solve the equation to find the value of x and then calculate the cost of the sweater.

Calculation:

- 700 + x + 5x = 2500 - 6x = 2500 - 700 - 6x = 1800 - x = 1800 / 6 - x = 300

So, the cost of the hat is 300 rubles.

Now, we can calculate the cost of the sweater: - Cost of the sweater = 5x = 5 * 300 = 1500 rubles.

Therefore, the cost of the sweater is 1500 rubles.

This calculation is based on the given information and the assumption that the cost of the hat is represented by x.
