Question

Первое число на 1,7 больше второго.Если первое число умножить на 2,3 а второе на 2,9, то разность этих чисел будет равна 1,75.Найдите эти числа. ПОМОГИТЕ СРОЧНО НАДО

Answer 1

х- второе число, х+1.7- первое число

(х+1.7)*2.3-2.9х=1.75

2.3х+3.91-2.9х=1.75

-0.6х=1.75-3.91

0.6х=2.16

х=2.16:0.6

х=3.6-второе число

3.6+1.7=5.3-первое число

Answer 2

х-второе число

(х+1,7)-первое число

(х+1,7)*2,3-2,9х=1,75

2,3х+3,91-2,9х=1,75

-0,6х=1,75-3,91

-0,6х=-2,16

х=3,6-второе число

3,6+1,7=5,3-первое число

 

Проверим:  5,3*2,3-3,6*2,9=1,75

                    12,19-10,44=1,75

                     1,75=1,75

 

Answer 3

Problem Analysis

We are given two numbers, where the first number is 1.7 greater than the second number. If we multiply the first number by 2.3 and the second number by 2.9, the difference between these two products is 1.75. We need to find the values of these two numbers.

Solution

Let's assume the second number is x. According to the problem statement, the first number is 1.7 greater than the second number, so the first number can be represented as x + 1.7.

We are also given that if we multiply the first number by 2.3 and the second number by 2.9, the difference between these two products is 1.75. Mathematically, this can be represented as:

(x + 1.7) * 2.3 - x * 2.9 = 1.75

To find the values of x and the first number, we can solve this equation.

Solving the Equation

Let's simplify the equation step by step:

(x + 1.7) * 2.3 - x * 2.9 = 1.75

Expanding the equation:

2.3x + 3.91 - 2.9x = 1.75

Combining like terms:

-0.6x + 3.91 = 1.75

Subtracting 3.91 from both sides:

-0.6x = 1.75 - 3.91

Simplifying:

-0.6x = -2.16

Dividing both sides by -0.6:

x = -2.16 / -0.6

Simplifying:

x = 3.6

Now that we have the value of x, we can substitute it back into the equation to find the first number:

First number = x + 1.7 = 3.6 + 1.7 = 5.3

Therefore, the two numbers are 3.6 and 5.3.

Answer

The first number is 5.3 and the second number is 3.6.
