Question

как понять число единиц на 5 больше числа десятковсумма числа единиц и числа десятков равна 8

Answer 1

Число единиц на 5 больше числа десятков:

пример:

число 16;

6>1 на 5;

Сумма числа единиц и числа десятков равна 8:

это значит, что если к еденицам прибавить десятки , то получится 8;

пример:

число 44;

4+4=8.

Answer 2

Understanding the Problem

You are trying to understand a number where the units digit is 5 more than the tens digit, and the sum of the units digit and the tens digit is equal to 8.

Solving the Problem

To solve this problem, we need to find a two-digit number that satisfies the given conditions. Let's break down the problem step by step:

1. The units digit is 5 more than the tens digit. 2. The sum of the units digit and the tens digit is equal to 8.

Let's assign variables to the tens and units digits to make it easier to solve the problem. Let's say the tens digit is represented by x and the units digit is represented by y.

According to the first condition, the units digit is 5 more than the tens digit. This can be represented as:

y = x + 5 According to the second condition, the sum of the units digit and the tens digit is equal to 8. This can be represented as:

x + y = 8 Now we have a system of two equations with two variables. We can solve this system of equations to find the values of x and y.

Solving the System of Equations

To solve the system of equations, we can use substitution or elimination. Let's use substitution in this case.

From equation (1), we have y = x + 5. We can substitute this value of y into equation (2):

x + (x + 5) = 8

Simplifying the equation:

2x + 5 = 8

Subtracting 5 from both sides:

2x = 3

Dividing both sides by 2:

x = 3/2 = 1.5

Since we are dealing with digits, the tens digit cannot be a decimal. Therefore, there is no solution that satisfies the given conditions.

Conclusion

Based on the given conditions, there is no two-digit number where the units digit is 5 more than the tens digit and the sum of the units digit and the tens digit is equal to 8.
