Question

Найдите корень уравнения: (x-1,25)*4,5=27, (x+19,64)*0,18=144, 5,6:x-6=34,03, x:100-1,2367=2,9633

Answer 1

1. (x-1,25)*4,5=27

4,5х-5,625=27

4,5х=27+5,625

4,5х=32,625

х=7,25

2.  (x+19,64)*0,18=144

0,18х+3,5352=144

0,18х=144-3,5352

0,18х=140,4648

х=780,36

3. 5,6:x-6=34,03

5,6:х=34,03+6

5,6:х=40,03

х=40,03*5,6

х=224,168

4. x:100-1,2367=2,9633

х:100=2,9633+1,2367

х:100=4,2

х=420

Answer 2

1)x-1.25=27/4.5
(x-1.25)/4.5/4.5=27/4.5
x=27+5.625/4.5
x-1.25+1.25=27/4.5+1.25
x=32.6252/4.5
2)x+19.64=144/0.18
(x+19.64)*0.18/0.18=144-0.18
x=144-3.5352/0.18
x+19.64-19.64=144/0.18-19.64
x=140.4648/0.18

Answer 3

1. (x-1,25)*4,5=27

Выразим x:

(x-1,25) = 27/4,5

x-1,25 = 6

x = 6+1,25

x = 7,25

Ответ: x = 7,25

2. (x+19,64)*0,18=144

Выразим x:

(x+19,64) = 144/0,18

x+19,64 = 800

x = 780,36

Ответ: x = 780,36

3. 5,6:x-6=34,03

Выразим x:

5,6/(x-6) = 34,03

5,6 = 34,03(x-6)

5,6 = 34,03x - 204,18

34,03x = 209,78

x = 6,162

Ответ: x = 6,162

4. x:100-1,2367=2,9633

Выразим x:

x/(100-1,2367) = 2,9633

x = 2,9633(100-1,2367)

x = 290,481

Ответ: x = 290,481
