Question

Помогите решить задачу пжжжж срочно надо!!!! За три дня в овощехранилище привезли 458952 т зерна. В первый и второй день привезли 158 459 т , во второй и третий день - 249 985 т зерна. Сколько тонн зерна привезли в каждый из трех дней?

Answer 1

Найди разницу ,то есть:249985-158459=91526(т)во второй день.Теперь надо найти ск-ко тонн привезли в 3 день:249985-91526=158459(т)-3 день и в 1:158459-91526=66933(т)-в первый день

Answer 2

Problem Analysis

To solve this problem, we need to determine the amount of grain delivered each day over a three-day period. We are given the total amount of grain delivered over the three days and the amounts delivered on specific pairs of consecutive days.

Solution

Let's denote the amount of grain delivered on the first day as x tons, the amount delivered on the second day as y tons, and the amount delivered on the third day as z tons.

From the problem statement, we know the following information: - The total amount of grain delivered over the three days is 458,952 tons. - On the first and second day, 158,459 tons of grain were delivered. - On the second and third day, 249,985 tons of grain were delivered.

We can set up the following equations based on the given information:

Equation 1: x + y + z = 458,952 (total amount of grain delivered over three days)

Equation 2: x + y = 158,459 (amount of grain delivered on the first and second day)

Equation 3: y + z = 249,985 (amount of grain delivered on the second and third day)

To solve this system of equations, we can use substitution or elimination. Let's use the elimination method to find the values of x, y, and z.

Subtracting Equation 2 from Equation 1, we get:

(x + y + z) - (x + y) = 458,952 - 158,459

Simplifying, we have:

z = 300,493

Subtracting Equation 3 from Equation 1, we get:

(x + y + z) - (y + z) = 458,952 - 249,985

Simplifying, we have:

x = 208,967

Now that we have the values of x, y, and z, we can determine the amount of grain delivered each day:

- On the first day: x = 208,967 tons - On the second day: y = 158,459 - x = 158,459 - 208,967 = -50,508 tons (negative value indicates a decrease in grain) - On the third day: z = 300,493 tons

However, a negative value for the amount of grain delivered on the second day doesn't make sense in this context. It suggests that there might be an error in the given information or the problem statement itself.

Please double-check the problem statement and the given values to ensure their accuracy. If there is an error, please provide the correct information so that we can help you solve the problem accurately.
