Answer 1

Ответ:

$x=1,5.$

Пошаговое объяснение:

$(6,2x+3,85)\cdot6,2=81,53\\38,44x+23,87=81,53\\38,44x=81,53-23,87\\38,44x=57,66\\x=57,66:38,44\\x=1,5.$

Проверка:

$(6,2\cdot1,5+3,85)\cdot6,2=81,53\\(9,3+3,85)\cdot6,2=81,53\\13,15\cdot6,2=81,53\\81,53=81,53.$

Answer 2

Ответ: откроем скобки 38,44*х+23,87=81,53⇒х=(81,53-23,87)/38,44=1,5.

Answer 3

To solve the equation (6.2x + 3.85) * 6.2 = 81.53, you can follow these steps:

1. Start by isolating the term with the variable (6.2x) on one side of the equation. You can do this by dividing both sides of the equation by 6.2:

(6.2x + 3.85) * 6.2 = 81.53 (6.2x + 3.85) = 81.53 / 6.2 6.2x + 3.85 = 13.2

2. Next, subtract 3.85 from both sides of the equation to isolate the 6.2x term:

6.2x + 3.85 - 3.85 = 13.2 - 3.85 6.2x = 9.35

3. Finally, to solve for x, divide both sides by 6.2:

6.2x / 6.2 = 9.35 / 6.2 x = 1.5

So, the solution to the equation is x = 1.5.
