Question

1. (x+5,74) - 3,2 = 5,8 2. 2,12+(5,4 - x) = 5,947 3. (x-5,257)+1,007=20,75 4. (29,x) + 54,2= 69,551

Answer 1

Ответ:

1(x+5.74)-3.2=5.8

x+5.74-3.2=5.8

x+2.54=5.8

x=5.8-2.54

x=3.26

2 2.12+(5.4-x)=5.947

2.12+5.4-x=5.947

7.52-x=5.947

-x=5.947-7.52

-x=-1.573/×(-1)

x=1.573

Answer 2

Ответ:

x=1.573

Пошаговое объяснение:

(x+5.74)-3.2=5.8

x+5.74-3.2=5.8

x+2.54=5.8

x=5.8-2.54

x=3.26

2 2.12+(5.4-x)=5.947

2.12+5.4-x=5.947

7.52-x=5.947

-x=5.947-7.52

-x=-1.573/×(-1)

x=1.573

Answer 3

To solve these equations, you'll need to isolate the variable x. Let's go through each equation step by step:

1. (x+5.74) - 3.2 = 5.8

First, simplify the equation:

x + 5.74 - 3.2 = 5.8

Now, subtract 5.74 and 3.2 from both sides of the equation:

x = 5.8 - 5.74 + 3.2

x = 0.06 + 3.2

x = 3.26

So, the solution to the first equation is x = 3.26.

2. 2.12 + (5.4 - x) = 5.947

First, simplify the equation:

2.12 + 5.4 - x = 5.947

Now, subtract 2.12 and 5.4 from both sides of the equation:

-x = 5.947 - 2.12 - 5.4

-x = -1.573

To solve for x, multiply both sides by -1:

x = 1.573

So, the solution to the second equation is x = 1.573.

3. (x-5.257) + 1.007 = 20.75

First, simplify the equation:

x - 5.257 + 1.007 = 20.75

Now, add 5.257 and 1.007 to both sides of the equation:

x = 20.75 - 5.257 - 1.007

x = 14.486

So, the solution to the third equation is x = 14.486.

4. (29, x) + 54.2 = 69.551

First, simplify the equation:

29 + x + 54.2 = 69.551

Now, subtract 29 and 54.2 from both sides of the equation:

x = 69.551 - 29 - 54.2

x = -13.649

So, the solution to the fourth equation is x = -13.649.
