Question

Собрали с 2х грядок по 9 кг.огурцов и нескольких грядок по 8 кг.помидоров всего собрали 74кг. овощей. ,.со скольких грядок собрали помидоры

Answer 1

2 * 9 = 18 кг.
8 кг * X= ?
всего 74 кг.
1) 2 * 9 =18 кг. огурцов
2) 74-18=56 кг.
3) 56 / 8 =7 кг грядок.

Answer 2

Х-это сколько грядок помидоров
2*9+8х=74
8х=74-18
8х=56
х=56:8
х=7 грядок помидор было

Answer 3

Calculating the Number of Tomato Beds

To calculate the number of tomato beds from which the tomatoes were harvested, we can use the given information. Let's denote the number of cucumber beds as x and the number of tomato beds as y.

Given: - Harvested from 2 cucumber beds, each yielding 9 kg of cucumbers. - Harvested from several tomato beds, each yielding 8 kg of tomatoes. - Total harvest weight of vegetables is 74 kg.

We can form the following equations based on the given information: 1. 2x * 9 + 8y = 74, where 2x represents the total weight of cucumbers and 8y represents the total weight of tomatoes.

Solving for the Number of Tomato Beds

To solve for the number of tomato beds, we can use the equation 2x * 9 + 8y = 74 and the fact that x and y are both non-negative integers.

Let's solve the equation to find the possible values for y.

Using the equation 2x * 9 + 8y = 74: - 18x + 8y = 74 - 8y = 74 - 18x - y = (74 - 18x) / 8

We need to find non-negative integer solutions for y.

Calculating the Number of Tomato Beds

Using the equation y = (74 - 18x) / 8, we can calculate the possible values of y for non-negative integer values of x.

Let's calculate the values of y for different non-negative integer values of x to find the number of tomato beds.

For x = 0: - y = (74 - 18*0) / 8 = 74 / 8 = 9.25

For x = 1: - y = (74 - 18*1) / 8 = 56 / 8 = 7

For x = 2: - y = (74 - 18*2) / 8 = 38 / 8 = 4.75

For x = 3: - y = (74 - 18*3) / 8 = 20 / 8 = 2.5

For x = 4: - y = (74 - 18*4) / 8 = 2 / 8 = 0.25

The number of tomato beds must be a non-negative integer, so the only valid solution is when x = 1, which gives y = 7.

Answer

Therefore, the tomatoes were harvested from 7 tomato beds.
