Question

В первый день маляры израсходовали 32 одинаковые банки краски,а во второй 27 таких же банок. Во второй день было израсходовано на 15 кг краски меньше. Сколько краки израсходована за 2 дня?

Answer 1

32-27=5(б.)-на первый день израсходовали больше краски .
15:5=3(кг)-весит одна банка
32*5=160(кг) весит краска израсх. в 1 день
27*5=135(кг) весит краска израсх. во 2 день
160+135=295 (кг) весят краски израсходованные за 2 дня

Answer 2

Problem Analysis

We are given that on the first day, the painters used 32 identical cans of paint, and on the second day, they used 27 identical cans of paint. Additionally, on the second day, they used 15 kg less paint than on the first day. We need to determine the total amount of paint used over the two days.

Calculation

To find the total amount of paint used over the two days, we need to add the amount used on the first day to the amount used on the second day.

Let's assume that the amount of paint used on the first day is represented by x kg. Therefore, the amount of paint used on the second day would be x - 15 kg.

The total amount of paint used over the two days would be x + (x - 15) kg.

Solution

To find the total amount of paint used over the two days, we need to solve the equation x + (x - 15) = ?.

Simplifying the equation, we get 2x - 15 = ?.

Since we don't have the exact value of x, we cannot determine the exact amount of paint used over the two days.

However, we can provide a general formula to calculate the total amount of paint used over the two days:

Total amount of paint used = 2x - 15 kg

Please note that the exact value of the total amount of paint used depends on the value of x, which is not provided in the question.

Answer

The total amount of paint used over the two days can be calculated using the formula Total amount of paint used = 2x - 15 kg, where x represents the amount of paint used on the first day.
