Homework Problems Help Me! Can anyone help me solve this problem!

The ice-water mix should be 0, the boiling water should be 100, the difference in the middle is 100, and the thermometer reading is 103, which is 3% more, and the reading -6 is also -3% more, so subtract -6- (so yes.)

Standard Answer: The ice water mixture should be 0, the boiling water should be 100, the middle difference is 100, and the thermometer reading is a difference so each scale on the thermometer represents the real temperature of 100 103, so when the thermometer is -6, the actual temperature is (100 103) *-6 = because each scale on the thermometer represents 100 103 of the actual temperature, so the 6 scales on the thermometer, whether it is negative or any one in the middle, he represents the actual temperature of 6*100 103, No need to add or subtract anything! Exact answer.

The temperature of ice water is 0, the temperature of boiling water is 100, and the temperature between 0 100 degrees Celsius is divided into 100 grids, and each grid is 1 degree Celsius

The temperature of the catchment is 100 degrees, which means that the temperature it measures is higher than the actual degree.

Since the normal temperature of ice water is 0 degrees, while the temperature of boiling water is 100 degrees. So 103 degrees in the current thermometer is equal to 100 degrees in reality. So now 1 degree is equal to the normal 100 103 degrees.

When it is -6 now, i.e. less than degrees, so the actual temperature now is degrees.

Addendum: What you don't understand now is that 103 degrees is **, right? You see, the actual thermometer shows 0 degrees in ice water and 100 degrees in hot water.

There is a difference of 100 degrees in the middle, so 1,100 of them are one degree. And now the thermometer is degrees in cold water and degrees in hot water, with a difference of 103 degrees in the middle. In other words, the temperature difference between the actual hot and cold water is 100 degrees Celsius, which is 103 degrees Celsius at the time of this thermometer, so the current 1 degree Celsius is the actual 100 103 degrees Celsius.

Problem description: It takes 12 hours for a steamer to travel from port A to port B, and 13 hours for a steamer to travel from port B to port A. The two steamers sailed opposite each other from the two ports at the same time, and after a few hours the two ships met.

Analytic Tubato: Equation, let the time be x

1/12x+1/13x=1

Just solve it.

1) Walking in the forest, the wind blows, breathing the breath of bamboo, and listening to the sound of bamboo leaves.

2) The little bamboo shoots are stretching and yawning!

Different from the original sentence: 1 It is more vivid before the modification 2 It is anthropomorphized before the modification.

If you remove the embellishment, it will make the article stiff and old-fashioned. Words are modified to make the article more vivid.

Suppose there are x chickens, then rabbits 50-x have; 2x+4 (50-x)=160 gives x=20, so there are 20 chickens and 30 rabbits.

Solution: Suppose there are x chickens and (50-x) rabbits. (Chicken and rabbit each have a head) 2x+4(50 a x) = 160 (chicken has two legs, rabbit has four legs).

The solution is x=20, and 50-x=30

A: There are 20 chickens and 30 rabbits.

There are x rabbits. Chickens have (50-x) .

Equation: 2x+4(50-x)=160 (because rabbits have two legs.) Chickens have four legs)

Is this elementary school or junior high school?

Solution: Suppose there are x chickens and (50-x) rabbits. (Chickens have two legs, rabbits have four legs).

2x+4(50-x)=160

The solution is x=20, and 50-x=30

A: There are 20 chickens and 30 rabbits.

If there are x chickens and y rabbits, then.

x＋y＝50

2x＋4y＝160

x＝20 y＝30

That is, there are 20 chickens and 30 rabbits.

If the chicken has x, the rabbit is 50-x

2x+4(50-x)=160

2x+200-4x=160

4x-2x=200-160

2x=40x=20

Answer: 20 chickens and 30 rabbits.

There are 50 chickens and rabbits, 2 times, that is, there are 100 rabbit feet with half of the chicken feet, then half of the rabbit feet are (160-100) = 60, that is, there are 30 rabbits and 20 chickens.

Set the original price to $x.

x（1-20%）=200

Solution x=250

250-200 = 50 yuan.

Thanks for adopting!

1. Assuming that the original price is x yuan, you can get the column: x * (1-20%) = 200 yuan: x = 250 yuan, 250-200 = 50 yuan is 50 yuan cheaper than the original price.

2. Direct column 200 (1-20%)-200

What is the process? The average number is to find out how many people visit the park in 7 days, that is, 12000 * 3 + 9000 * 2 + 8000 + 6000 = 68000, filial piety and then divide by 7 to know the average number of people visiting the park every day, that is, 68000 7 = 9714
