Question

Б) (0,34 - x): 0,01 = 6;в) 6,4 : (х – 2,09) = 6,528;г) 5,3х +1,8 = 134,3​

Answer 1

Ответ:

Пошаговое объяснение:

б)

(0,34 - x): 0,01 = 6;

0,34 - x = 6*0,01

0,34 - x = 0,06

x = 0,34 - 0,06

x = 0,28

в)

6,4 : (х – 2,09) = 6,528;

x - 2,09 = 6,4 : 6,528

x - 2,09 = 50/51

x = 50/51 + 2,09

x = 50/51 + 209/100

x = 5000/5100 + 10659/5100

x = 15659/5100

x = 3ц. 359/5100

г)

5,3х +1,8 = 134,3​

5,3x = 134,3 - 1,8

5,3x = 132,5

x = 132,5 : 5,3

x = 25

Answer 2

Ответ:

Б= х=0,28

В=3.11

Г=25

Пошаговое объяснение:

Б)

0,34-Х=6*0,01

0.34-х=0.06

х=0.34-0.06

х=0.28

В)

6.4:(х-2.09)=6.528

х-2.09=1.02

х=1.02+2.09

х=3.11

Г)5.3х+1.8=134.3

5,3х=134,3-1,8

5,3х=132,5

х=132,5/5,3

х=25

5,3х25+1,8=134,3

Answer 3

а) To solve the equation (0.34 - x) / 0.01 = 6, you can follow these steps:

1. Multiply both sides of the equation by 0.01 to eliminate the division: 0.01 * [(0.34 - x) / 0.01] = 0.01 * 6. This simplifies the equation to (0.34 - x) = 0.06.

2. Move the constant term to the other side of the equation by subtracting 0.34 from both sides: (0.34 - x) - 0.34 = 0.06 - 0.34. This simplifies to -x = -0.28.

3. Multiply both sides of the equation by -1 to isolate the variable x: (-1) * (-x) = (-1) * (-0.28). This yields x = 0.28.

Therefore, the solution to the equation is x = 0.28.

б) To solve the equation 6.4 / (x - 2.09) = 6.528, you can follow these steps:

1. Multiply both sides of the equation by (x - 2.09) to eliminate the division: (x - 2.09) * (6.4 / (x - 2.09)) = 6.528 * (x - 2.09). This simplifies the equation to 6.4 = 6.528 * (x - 2.09).

2. Distribute 6.528 on the right side of the equation: 6.4 = 6.528x - 13.602432.

3. Move the constant term to the other side of the equation by adding 13.602432 to both sides: 6.4 + 13.602432 = 6.528x - 13.602432 + 13.602432. This simplifies to 19.002432 = 6.528x.

4. Divide both sides of the equation by 6.528 to solve for x: 19.002432 / 6.528 = (6.528x) / 6.528. This yields x = 2.909...

Therefore, the solution to the equation is approximately x = 2.909.

г) To solve the equation 5.3x + 1.8 = 134.3, you can follow these steps:

1. Subtract 1.8 from both sides of the equation: 5.3x + 1.8 - 1.8 = 134.3 - 1.8. This simplifies to 5.3x = 132.5.

2. Divide both sides of the equation by 5.3 to solve for x: (5.3x) / 5.3 = 132.5 / 5.3. This yields x = 25.

Therefore, the solution to the equation is x = 25.
