Answer 1

Пусть масса тыквы х  , по условию масса картофеля равна (17800+х)*2=42кг.,   (17800+х)*2=42000  17800+х=42000:2  17800+х=21000  х=21000-17800 х=3200г.-масса тыквы  Ответ: 3кг.200г.

в)с-42000=17800*2  с-42000=35600  с=35600+42000  с=77600

б)17800+у=42000:2   17800+у=21000  у=21000-17800  у=3200
а)х:2=42000-17800    х:2=24200  х=24200:2  х=12100

Answer 2

Solution:

Let's solve the equations and find the mass of the pumpkin (тыква) in the given problem.

a) Equation: x/2 = 42000 - 17800

To solve this equation, we can multiply both sides by 2 to eliminate the fraction:

x = 2 * (42000 - 17800) x = 2 * 24200 x = 48400

So, the value of x is 48400.

b) Equation: 17800 + y = 42000/2

To solve this equation, we can simplify the right side of the equation:

17800 + y = 21000

Next, we can subtract 17800 from both sides to isolate y:

y = 21000 - 17800 y = 3200

So, the value of y is 3200.

c) Equation: c - 42000 = 17800 * 2

To solve this equation, we can simplify the right side of the equation:

c - 42000 = 35600

Next, we can add 42000 to both sides to isolate c:

c = 35600 + 42000 c = 77600

So, the value of c is 77600.

Problem:

The problem states that there are apples with a total mass of 17800 grams, a pumpkin (тыква), and 42 kilograms of potatoes. We need to find the mass of the pumpkin if the mass of the potatoes is twice the sum of the masses of the apples and the pumpkin.

Let's denote the mass of the pumpkin as p.

According to the problem, the mass of the potatoes is twice the sum of the masses of the apples and the pumpkin:

42 kg = 2 * (17800 g + p)

To solve this equation, we need to convert the mass of the potatoes to grams:

42 kg = 42000 g

Now we can substitute the values and solve for p:

42000 g = 2 * (17800 g + p)

Divide both sides of the equation by 2:

21000 g = 17800 g + p

Subtract 17800 g from both sides:

3200 g = p

So, the mass of the pumpkin is 3200 grams.
