Реши уравнение с проверкой. 1)45: y = 72 :82) 1 62 + х = 509 – 683)1000 – a = 146 * 6срочнооооо​

Answer 1

Ответ:

45 : у = 72 : 8

45 : у = 9

у = 45 : 9

у= 5

45 : 5 = 72 : 8

9 = 9

-----------------------

162 + х = 509 - 68

162 + х = 441

х = 441 - 162

х = 279

162 + 279 = 509 -68

441 = 441

------------------------

1000 - а = 146 * 6

1000 - а = 876

а = 1000 - 876

а = 124

1000 - 124 = 146 * 6

876 = 876

Answer 2

Ответ:

у=5

х=279

а=124

Answer 3

#### Solving the equation 45 + y = 72 + 82 + 1 + 62 To solve the equation 45 + y = 72 + 82 + 1 + 62, we need to isolate the variable y on one side of the equation. Here's how we can do it step by step: 1. Combine the numbers on the right side of the equation: 72 + 82 + 1 + 62 = 217. 2. Subtract 217 from both sides of the equation to isolate the variable y: 45 + y - 217 = 217 - 217 Simplifying the left side of the equation gives us: y - 172 = 0 3. Add 172 to both sides of the equation to solve for y: y - 172 + 172 = 0 + 172 Simplifying the equation gives us: y = 172 Therefore, the solution to the equation 45 + y = 72 + 82 + 1 + 62 is y = 172. #### Solving the equation 509 – 683 = 1000 – a * 6 To solve the equation 509 – 683 = 1000 – a * 6, we can follow these steps: 1. Subtract 683 from 509: 509 - 683 = -174 2. Multiply 6 by a: 6a 3. Subtract the result from step 2 from 1000: 1000 - 6a 4. Set the result from step 1 equal to the result from step 3 and solve for a: -174 = 1000 - 6a 5. To isolate a, subtract 1000 from both sides of the equation: -174 - 1000 = -6a Simplifying the left side of the equation gives us: -1174 = -6a 6. Divide both sides of the equation by -6 to solve for a: -1174 / -6 = a Simplifying the equation gives us: a = 195.67 (rounded to two decimal places) Therefore, the solution to the equation 509 – 683 = 1000 – a * 6 is a ≈ 195.67. Please note that the solutions provided have been calculated based on the given equations.
