Question

Помогите ещё раз??? Не выполняя вычислений определи корни каких уравнений кратны числу 3: а) х:303=23 937; б) х+ 405= 936; в) 80073+х= 96814; г) х- 819= 54 распишите пожалуйста как нужно это правильно записать в тетрадь

Answer 1

А)х=23937:303=79
б)х=936-405=531
в)х=96814-80073=16741
г)х=54+819=873

Answer 2

Ответы под б и г, так как сумма цифр чисел, находящихся в уравнении делится на 3, следовательно и полученный корень уравнения тоже будет кратен 3.

Answer 3

Equations with Roots Divisible by 3

To determine the equations whose roots are divisible by 3 without performing calculations, we can analyze the given equations and look for patterns or properties that indicate divisibility by 3.

a) Equation: x/303 = 23,937

To determine if the roots of this equation are divisible by 3, we need to examine the coefficients and constants. In this case, the coefficient of x is 1, which is not divisible by 3. Therefore, the roots of this equation are not divisible by 3.

b) Equation: x + 405 = 936

Similar to the previous equation, we need to analyze the coefficients and constants. In this case, the coefficient of x is 1, which is not divisible by 3. Therefore, the roots of this equation are not divisible by 3.

c) Equation: 80,073x = 96,814

Again, we analyze the coefficients and constants. In this case, the coefficient of x is 80,073, which is not divisible by 3. Therefore, the roots of this equation are not divisible by 3.

d) Equation: x - 819 = 54

Once more, we analyze the coefficients and constants. In this case, the coefficient of x is 1, which is not divisible by 3. Therefore, the roots of this equation are not divisible by 3.

To summarize, none of the given equations have roots that are divisible by 3.

Now, let's discuss how to correctly write this information in your notebook.
