Question

Надир увеличил задуманное число в 100 раз и получил равный сумме чисел 1600 и 24000 4 класс помогите(уравнением!!)алия уменьшила задуманное число на 30985 результат уменьшила в 15 раз и получила число равное разности чисел 12000 и 9731 какое число задумала алия?тоже уравнением

Answer 1

100x = 1600 + 24000

100x = 25600

x = 256

Answer 2

100x=1600+24000
100x=25600
x=256

Answer 3

Problem Analysis

To solve this problem, we need to find the value of the number that Nadir and Aliya had in mind. We are given two sets of equations:

1. Nadir's equation: - Nadir increased the number by 100 times and obtained a sum of 1600 and 24000. - Let's represent the number Nadir had in mind as x. - The equation can be written as: 100x = 1600 + 24000.

2. Aliya's equation: - Aliya decreased the number by 30985 and obtained a result that was 15 times smaller than the difference between 12000 and 9731. - Let's represent the number Aliya had in mind as y. - The equation can be written as: y - 30985 = 15 * (12000 - 9731).

Now, let's solve these equations to find the values of x and y.

Solving Nadir's Equation

To solve Nadir's equation, we can simplify it by performing the addition on the right side:

100x = 1600 + 24000 100x = 25600

Now, divide both sides of the equation by 100 to isolate x:

x = 25600 / 100 x = 256

So, Nadir had the number 256 in mind.

Solving Aliya's Equation

To solve Aliya's equation, we can simplify it by performing the subtraction and multiplication on the right side:

y - 30985 = 15 * (12000 - 9731) y - 30985 = 15 * 2269 y - 30985 = 34035

Now, add 30985 to both sides of the equation to isolate y:

y = 34035 + 30985 y = 65020

So, Aliya had the number 65020 in mind.

Conclusion

- Nadir had the number 256 in mind. - Aliya had the number 65020 in mind.
