Question

по первой накладной со склада было выдано 0,7 имевшегося кирпича, а по второй - 0,4 остатка, после чего кирпича на складе осталось 5850 штук.Какое количество кирпича было на складе первоначально?за рание спасибо решить с вопросами!!!

Answer 1

Х-было на складе первоначально
0.7 х-выдали по первой накладной
1-0.7-осталось после этого
0.4(1-0.7)-выдали по второй накладной
х-5850 -выдали по двум накладным

0.7х+0.4(1-0.7)х=х-5850
0.7х+0.12х=х-5850
0.82х-х=-5850
-0.18х=-5850
х=32500

Answer 2

Calculation of Initial Brick Quantity

To calculate the initial quantity of bricks on the warehouse, we can use the information provided in the question. Let's break down the given information:

- From the first invoice, 0.7 of the available bricks were issued. - From the second invoice, 0.4 of the remaining bricks were issued. - After these transactions, there were 5850 bricks left on the warehouse.

To find the initial quantity of bricks, we need to determine the total quantity of bricks before any issuances. We can use the following equation:

Initial Quantity - (First Invoice + Second Invoice) = Remaining Quantity

Let's substitute the given values into the equation:

Initial Quantity - (0.7 * Initial Quantity + 0.4 * (Initial Quantity - 0.7 * Initial Quantity)) = 5850

Simplifying the equation:

Initial Quantity - (0.7 * Initial Quantity + 0.4 * 0.3 * Initial Quantity) = 5850

Initial Quantity - (0.7 * Initial Quantity + 0.12 * Initial Quantity) = 5850

Initial Quantity - 0.82 * Initial Quantity = 5850

0.18 * Initial Quantity = 5850

Now, we can solve for the initial quantity of bricks:

Initial Quantity = 5850 / 0.18

Calculating the result:

Initial Quantity = 32500

Therefore, the initial quantity of bricks on the warehouse was 32,500.
