Question

Какое число на координатной прямой удалено:1)от числа -4 вправо на 9 единиц; 2)от числа 3 влево на 10 единиц; 3)от числа -2 влево на 8 единиц? Запишите арифметические действия,соответствующие этим изменениям.

Answer 1

1) -4+9=5 это число 5; 2) 3-10=-7 это число -7; 3) -2-8=-10 это число -10;

Answer 2

Calculating Distances on the Number Line

To calculate the distances on the number line as described, we can use the following arithmetic operations:

1) From -4 to the right by 9 units: - This involves adding 9 to -4. - The calculation is: -4 + 9 = 5.

2) From 3 to the left by 10 units: - This involves subtracting 10 from 3. - The calculation is: 3 - 10 = -7.

3) From -2 to the left by 8 units: - This involves subtracting 8 from -2. - The calculation is: -2 - 8 = -10.

These calculations represent the distances on the number line as described.
