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

Let's solve each equation step by step:

a) (0.34 - x) / 0.01 = 6

To isolate x, we can multiply both sides of the equation by 0.01:

0.34 - x = 6 * 0.01

0.34 - x = 0.06

Now, let's isolate x by subtracting 0.34 from both sides:

-x = 0.06 - 0.34

-x = -0.28

Finally, we can solve for x by multiplying both sides by -1:

x = 0.28

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

b) 6.4 / (x - 2.09) = 6.528

To solve for x, we can start by multiplying both sides by (x - 2.09):

6.4 = 6.528 * (x - 2.09)

Next, distribute 6.528:

6.4 = 6.528x - 13.589152

Now, let's isolate x by adding 13.589152 to both sides:

6.4 + 13.589152 = 6.528x

19.989152 = 6.528x

Finally, divide both sides by 6.528 to solve for x:

x = 19.989152 / 6.528

x ≈ 3.061

So, the solution to the equation is x ≈ 3.061.

c) 5.3x + 1.8 = 134.3

To isolate x, let's start by subtracting 1.8 from both sides:

5.3x = 134.3 - 1.8

5.3x = 132.5

Now, divide both sides by 5.3:

x = 132.5 / 5.3

x ≈ 25

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