Uncle Wang contracted 25 acres of land and switched to planting eggplant and tomatoes in two greenho

Set eggplant has x acres of fields, tomatoes have y acres of fields, from the title:

x+y=25

1700x+1800y=44000

Solution: x=10 y=15

Therefore, Uncle Wang made a total profit of 10 * 2400 + 15 * 2600 = 63,000 yuan.

Answer: A total profit of 63,000 yuan.

Replanted with eggplant x acres and tomatoes 25-x acres.

17x+18（25-x）=440

17x-18x+450=440

x = 10 profit = 10 * 2400 + 15 * 2600 = 63000

Uncle Wang contracted 25 acres of land and switched to planting eggplant and tomatoes in two greenhouse vegetables this spring

Bounty Points: 0 - 14 days and 13 hours until the end of the question.

Uncle Wang contracted 25 acres of land, and this spring switched to planting eggplant and tomatoes in two greenhouse vegetables, sharing 44,000 yuan. Among them, the cost of planting eggplants per mu is 1,700 yuan, and the net profit is 2,400 yuan, and the cost of planting tomatoes per mu is 1,800 yuan, and the net profit is 2,600 yuan. Replanted with eggplant x acres and tomatoes 25-x acres.

17x+18（25-x）=440

17x-18x+450=440

x = 10 profit = 10 * 2400 + 15 * 2600 = 63000

This little classmate, you have to use your own brain to calculate the application problems, how can you come and ask your uncles to make ready-made?

There are even some uncles who don't pay attention to it, and they don't even care about the growth of the next generation for the sake of a few points.

Summary. Answer: 1 3 (one-third) of the area of eggplant Total area - area of yellow flowers - area of tomatoes 12-3-5 4 acres of total area: 4 12 1 3 (one-third).

1.Uncle Li has a 12-acre plot, of which 3 acres are planted with cucumbers, 5 acres are planted with tomatoes, and the rest are planted with eggplants.

Uncle Li has a 12-acre plot, of which 3 acres are planted with cucumbers, 5 acres are planted with tomatoes, and the rest are planted with eggplants. I'm answering for you :

Hello before answering pants! According to the current Qingqing topic information, Uncle Li has a 12-acre land, of which 3 acres are planted with cucumbers, 5 acres are planted with Xihong Chun persimmons, and the rest is planted with eggplants? This is a simple calculation problem.

The first. The area of eggplant planting Total area - yellow flower area - tomato area 12-3-5 4 acres.

Answer: 4 acres of eggplant area Total area - yellow flower area - tomato area 12-3-5 4 acres.

Ask a fraction of a fraction.

Good. Answer: 1 3 (1 3 points) of the area of eggplant Total area of the front area - yellow flower area - tomato area 12-3-5 4 acres of total area: 4 12 1 3 (one-third).

Answer: 1 3 (1 3 points) of the area of eggplant Total area of the front area - yellow flower area - tomato area 12-3-5 4 acres of total area: 4 12 1 3 (one-third).

Uncle Wang planted x acres of eggplants and y acres of tomatoes:

x+y=25

1700x+1800y=44000

That is: 17x+17y=25*17

17x+18y=440

Solve the system of equations: x=10, y=15;

Uncle Wang received a total of net profits:

2250x+2400y=2250*10+2400*15=58500 (yuan).

Solution: Uncle Wang planted x acres of eggplants and Y acres of tomatoes, according to the title:

x+y=25 1700x+1800y=44000. x=10y=15

Total net profit: 2400 10 + 2600 15 = 63000 (yuan), A: Uncle Wang received a total net profit of 63000 yuan

Thank you so much, I won't write this question either.

Set up x acres of eggplant.

1700x + 1800(25-x) = 44000 gives x = 10

So profit (2250-1700)*10 + 2400-1800)*(25-10)=14500 yuan.

Uncle Wang made a total profit of 58,500 yuan.

If you plant eggplant x mu, then tomato (25-x) mu will have 1700x+1800(25-x)=44000 x=10

Uncle Wang made a total profit of 2250*10+2400*(25-10)=58500

Solution: Let the number of eggplants be x yuan.

1700x+(25-x)1800=4400x=10

2400x10 + 2600x (multiplied) 15 = 63000

Solution: If the eggplant is x hectares, then the tomato is (25-x) hectares 1700x+1800(25-x)=44000 1700x+45000-1800x=44000

100x=-1000

x=10 25-10=15 (hectares) 2400x10 + 15x2600=63000 (yuan) to give points, the process is very detailed.

Solution: If Uncle Wang plants x acres of eggplant, he will plant tomatoes (25-x) acres, according to the title

1700x + 1800(25-x) = 44000 gives x = 10

So 25-x=15

Therefore, Uncle Wang made a total of net profits:

10 2400 + 15 2600 = 63000 (yuan) Answer: Uncle Wang received a total net profit of 63,000 yuan.

The area of eggplants is x hectares and the area of tomatoes is y hectares;

then x+y=25

1700x+1800y=44000；

These two equations are solved to obtain x=10 and y=15;

Profit: 2400 * 8 + 17 * 2600 = 476800 yuan.

Solution: If the eggplant is x hectares, then the tomato is (25-x) hectares of eggplant 1700x+1800(25-x)=44000 1700x+45000-1800x=44000

100x=-1000

x=10 tomatoes 25-x=15 (ha).

Net profit: 2400x10 + 15x2600 = 63000 (yuan) Our teacher talked about it.

Set x hectares of eggplant, (25-x) hectares of tomatoes.

1700x + 1800 (25-x) = 44000x = 8, then tomatoes = 25-8 = 17 hectares.

A total profit of 2400 * 8 + 17 * 2600 = 476800 yuan.

Solution: If you have x hectares of eggplant, then (25-x) hectares of tomatoes.

Eggplant 1700x + 1800 (25-x) = 44000

Solution: If the eggplant is x hectares, then the tomato is (25-x) hectares 1700x+1800(25-x)=44000 1700x+45000-1800x=44000

100x=-1000

x=10 25-10=15 (hectares) 2400x10+15x2600=63,000 (yuan), so a total profit of 63,000 yuan.

Solution: Set up x acres of eggplant and y acres of tomatoes.

Solution: If you plant tomatoes x mu, plant tomatoes y mu x+y=25

1700x+1800y=44000

Solution: x=10 y=15

So or profit 2400 * 10 + 2600 * 15 = 63000 yuan rent macro.

Set up cucumbers x acres.

1700x+(18-x)*1800=31600 gives x=8

So plant 8 acres of cucumbers and 10 acres of tomatoes.

Profit of 45,200 yuan.

If the firepower per mu is net profit, it is 45200. If it's a gross profit, it's 13,600

If the eggplant is x acres, then the tomato is y wow, 1700x+1800y=44000x+y=25

And then it's solved.

Then 2400x+2600y-44000

You can find the value of the profit.

If the eggplant is x acres, then the tomatoes are 25-x

1700x=1800(25-x)=44000x=10

That is, plant 10 acres of eggplants and 15 acres of tomatoes.

Profit in one year = 2400 * 10 + 2600 * 15 - 44000 = 19000 yuan 25 acres of land in a year profit of 19000 yuan, such an investment --- you will do?

Missing the main point of how many acres of tomato and eggplant each.

The topic is: Uncle Wang contracted 25 acres of land, and changed to plant eggplant and tomatoes in the spring of this year, using 44,000 yuan, of which 1,700 yuan per mu was used to plant eggplant, and the net profit was 2,400 yuan, and 1,800 yuan was used to plant tomatoes, and the net profit was 2,600 yuan.

Solution: Let the number of eggplants be x, and the column formula is.

1700x+(25-x)1800=44000 is solved to call Hu x=10, that is, 10 acres of eggplant and 15 acres of tomatoes.

2400 * 10 + 2600 * 15 = 63,000 yuan, a total profit of 63,000 yuan.
