69000÷а=92-4 1256+у=3020-56 Х÷2=39000÷3

Answer 1

Ответ:

Пошаговое объяснение:

69000÷а=92-4

69000:а=88

А=69000:88

А=784 1/11

1256+у=3020-56

1256+у=2964

У=2964-1256

У=1708

Х÷2=39000÷3

Х:2=13000

Х=13000*3

Х=26000

Answer 2

Х=26000

Answer 3

Let's solve the given equations step by step:

1. 69000 ÷ а = 92 - 4

To isolate 'а', we'll subtract 4 from both sides of the equation:

69000 ÷ а + 4 = 92 - 4 + 4

69000 ÷ а + 4 = 92

Now, we'll subtract 4 from both sides again:

69000 ÷ а + 4 - 4 = 92 - 4

69000 ÷ а = 88

To solve for 'а', we'll multiply both sides by 'а':

а * (69000 ÷ а) = 88 * а

69000 = 88а

Dividing both sides by 88:

69000 ÷ 88 = 88а ÷ 88

784.09 = а

So, the value of 'а' is approximately 784.09.

2. 1256 + у = 3020 - 56

To isolate 'у', we'll subtract 1256 from both sides of the equation:

1256 + у - 1256 = 3020 - 56 - 1256

у = 1764 - 1256

у = 508

So, the value of 'у' is 508.

3. Х ÷ 2 = 39000 ÷ 3

To isolate 'Х', we'll multiply both sides of the equation by 2:

2 * (Х ÷ 2) = 2 * (39000 ÷ 3)

Х = 78000 ÷ 3

Х = 26000

So, the value of 'Х' is 26000.

To summarize:

а ≈ 784.09 у = 508 Х = 26000
