Answer 1

Ответ:

Пошаговое объяснение:

1) 1376÷(34-x)=86

34-x=1376/86

x=34-16=18

2) 9680÷(x·219)=16

219x=9680/16

x=605/219=2 167/219

3) (x-57)÷29=205

x-57=205·29

x=5945+57=6002

4) (x-72)·9=927

x-72=927/9

x=103+72=175

Answer 2

To solve these equations, let's break them down one by one:

1. 1 376 : (34 - 0) = 86

In this equation, you need to divide 1,376 by the difference between 34 and 0. Since 34 - 0 = 34, the equation becomes:

1,376 ÷ 34 = 86

So, the equation is correct.

2. 9 680 : (.* 219) = 16;570 Oy

It seems that there is a typo or an error in this equation. The term "(.* 219)" is not clear and doesn't represent a valid mathematical operation. Could you please clarify or correct the equation?

3. (X - 57): 29 = 205

In this equation, you are solving for X. To isolate X, you need to multiply both sides of the equation by 29:

29 * (X - 57) = 205

Distribute 29:

29X - 1,653 = 205

Now, isolate X by adding 1,653 to both sides:

29X = 205 + 1,653 29X = 1,858

Finally, divide both sides by 29:

X = 1,858 ÷ 29 X ≈ 64.07

So, X is approximately 64.07.

4. (X - 72) * 9 = 927

Similarly, you need to solve for X in this equation. Begin by dividing both sides by 9:

(X - 72) * 9 ÷ 9 = 927 ÷ 9

Simplify:

X - 72 = 103

Now, isolate X by adding 72 to both sides:

X = 103 + 72 X = 175

So, X is equal to 175.

To summarize:

1. 1,376 ÷ (34 - 0) = 86
2. Please clarify or correct the equation.
3. X ≈ 64.07
4. X = 175
