Answer 1

Уравнение б
x + ( 3 983 + 7 267) = 12 000
x + 11250 = 12 000,
х=12000-11250
х=750кг весит жираф Петька

Answer 2

Solving the Equation

To solve the equation, let's consider each option and find the value of x.

a) (x - 3,983) + 7,267 = 12,000 b) x + (3,983 + 7,267) = 12,000 c) x - 3,983 = 12,000 + 7,267

Let's solve each equation step by step.

a) (x - 3,983) + 7,267 = 12,000 - First, let's simplify the equation by removing the parentheses: x - 3,983 + 7,267 = 12,000 - Next, let's combine like terms: x + 3,284 = 12,000 - To isolate x, we subtract 3,284 from both sides of the equation: x = 12,000 - 3,284 - Calculating the right side of the equation: x = 8,716

b) x + (3,983 + 7,267) = 12,000 - First, let's simplify the equation by adding the numbers inside the parentheses: x + 11,250 = 12,000 - Next, let's isolate x by subtracting 11,250 from both sides of the equation: x = 12,000 - 11,250 - Calculating the right side of the equation: x = 750

c) x - 3,983 = 12,000 + 7,267 - First, let's simplify the equation by adding the numbers on the right side: x - 3,983 = 19,267 - Next, let's isolate x by adding 3,983 to both sides of the equation: x = 19,267 + 3,983 - Calculating the right side of the equation: x = 23,250

Therefore, the solutions to the equation are: a) x = 8,716 b) x = 750 c) x = 23,250

Finding the Mass of Giraffe "Petka"

In the given problem, we are provided with the masses of three animals in a zoo: an Indian elephant named Rajah with a mass of 3,983 kg, an African elephant named Buba with a mass of 7,267 kg, and an unnamed giraffe. The total mass of these three animals together is 12,000 kg.

To find the mass of the giraffe, we need to subtract the masses of the two elephants from the total mass.

Total mass of Rajah and Buba: 3,983 kg + 7,267 kg = 11,250 kg

Mass of the giraffe (Petka): **Total mass - (Mass
