Question

Масса слонав 5 раз больше массы бегемота.Чему равна масса слона,если масса бегемота на 4 тонны меньше?

Answer 1

слон - 5х

бегемот - х+4

 

1) 5х=х+4

5х-х=4

4х=4

х=4:4

х=1 т - масса бегемота

2) 1+4=5 т - масса слона

Answer 2

Пусть слон весит Х, тогда бегемот весит 1/5 х. Разность их масс составляет 4 тонны: 
х - 1/5 х = 4 
4/5 х = 4 
х = 4 * 5 / 4 
х = 5 
Ответ: масса слона 5 тонн 

P.S. бегемот весит 1/5 * 5т = 1т 
5т - 1т = 4т

Answer 3

Calculation of the Elephant's Mass

To find the mass of the elephant, we need to compare it to the mass of the hippopotamus. Given that the mass of the elephant is 5 times greater than the mass of the hippopotamus and that the hippopotamus weighs 4 tons less, we can set up the following equation:

Elephant's mass = Hippopotamus's mass + 4 tons

Let's denote the mass of the hippopotamus as x. According to the given information, the mass of the elephant is 5 times greater than the mass of the hippopotamus, so we can write:

Elephant's mass = 5 * Hippopotamus's mass

Substituting the value of the elephant's mass from the equation above, we have:

5 * Hippopotamus's mass = Hippopotamus's mass + 4 tons

Simplifying the equation, we get:

4 * Hippopotamus's mass = 4 tons

Now, we can solve for the mass of the hippopotamus:

Hippopotamus's mass = 4 tons / 4

Converting tons to a more common unit of mass, such as kilograms, we have:

Hippopotamus's mass = 4000 kg / 4

Calculating the mass of the hippopotamus, we find:

Hippopotamus's mass = 1000 kg

Finally, substituting the mass of the hippopotamus into the equation for the elephant's mass, we get:

Elephant's mass = 5 * 1000 kg

Calculating the mass of the elephant, we find:

Elephant's mass = 5000 kg

Therefore, the mass of the elephant is 5000 kilograms.

Answer:

The mass of the elephant is 5000 kilograms.
