Answer 1

30 000:4=7500 костюмов продали в 1 день
50 000:4=12500костюмов продали во 2 день

182*30+7640:20=5460+382=5842
382*20-5640:30=7640-188=7452

Answer 2

Task 6: In a store, 8 children's costumes were sold over the course of two days at the same price. On the first day, the total sales amount for the costumes was 30,000 Tenge, and on the second day, it was 50,000 Tenge. The task is to determine how many costumes were sold on each day.

Let's assume that x costumes were sold on the first day and y costumes were sold on the second day.

To solve this problem, we can set up a system of equations based on the given information:

Equation 1: x + y = 8 (since a total of 8 costumes were sold over the two days) Equation 2: x * 30,000 + y * 50,000 = total sales amount

We can solve this system of equations to find the values of x and y.

To solve Equation 2, we need to substitute the values of x and y from Equation 1 into Equation 2:

x * 30,000 + y * 50,000 = total sales amount x * 30,000 + (8 - x) * 50,000 = total sales amount 30,000x + 400,000 - 50,000x = total sales amount -20,000x = total sales amount - 400,000 x = (400,000 - total sales amount) / 20,000

Now, let's substitute the given sales amounts into the equation to find the value of x:

For the first day: x = (400,000 - 30,000) / 20,000 = 370,000 / 20,000 = 18.5 For the second day: y = 8 - x = 8 - 18.5 = -10.5

Since we cannot have a negative number of costumes sold, it seems there may be an error in the given information or calculations. Please double-check the values provided for the sales amounts on each day.

Task 8: The task is to write an expression and evaluate it by performing addition, multiplication, and division operations.

The expression is as follows: 1. Add the numbers 182 and 30: 182 + 30 = 212 2. Divide the result by the numbers 7640 and 20: 212 / (7640 / 20) = 212 / 382 = 0.55497 (rounded to 5 decimal places) 3. Subtract the result from the numbers 382 and 20: 382 - (0.55497 * 20) = 382 - 11.0994 = 370.9006 (rounded to 4 decimal places)

Therefore, the final result of the expression is approximately 370.9006.
