Answer 1

Ответ:

5.6a=4+0.25

5.6a=4.25

a=4.25÷5.6

a=0,8

Answer 2

Ответ:

а = 85/112

Пошаговое объяснение:

5,6a - 0,25 = 4

Преобразуем десятичные дроби в обыкновенные:

56/10а = 4 + 25/100

28/5а = 4 + 1/4

28/5а = 4 1/4

28/5а = 17/4

а = 17/4 : 28/5

а = 17/4 * 5/28

а = 85/112

Проверим:

28/5 * 85/112 - 1/4 = 4

17/4 - 1/4 = 4

16/4 = 4

4 = 4

Answer 3

To solve the equation, follow these steps:

1. Remove any unnecessary symbols or parentheses: 5,6a - 0,25 = 4

2. Replace the comma (,) with a period (.) as it is used as a decimal separator in many countries: 5.6a - 0.25 = 4

3. Isolate the variable term (in this case, 'a') on one side of the equation by performing operations to both sides:

   Start by moving the constant term (in this case, -0.25) to the other side: 5.6a = 4 + 0.25 5.6a = 4.25

4. Now, isolate 'a' by dividing both sides by the coefficient of 'a' (in this case, 5.6): a = 4.25 / 5.6 a ≈ 0.7589285714285714 (rounded to 15 decimal places)

So, the approximate value of 'a' that solves the equation is 0.7589 (rounded to four decimal places).
