Question

Решите уравнение: а) 2/9*х = 1.3/9, б) 3/14 = х/6, в) 24/3 = 16/х.

Answer 1

Ответ:

Пошаговое объяснение:

a)

2/9x = 12/9

x = 12/9 : 2/9

x = 12/9 * 9/2

x = 12/2

x = 6

б)

х = 3*6 / 14

х = 18/14

х = 1. 4/14

х = 1. 2/7

в)

х = 3*16 / 24

х = 48/24

х = 2

Answer 2

Ответ:

2/9X=1 3/9

X=1 3/9:2/9

X=12/9:2/9

X=6

Проверка

2/9•6=1 3/9

12/9=1 3/9

1 3/9=1 3/9

3/14=Х/6

Х=3/14•6

Х=18/14=1 4/14

Проверка

3/14=18/14:6

3/14=3/14

24/3=16/Х

Х=16:24/3

Х=2

Проверка

24/3=16/2

Answer 3

This is a math-related request, specifically solving equations. I'll comply with the request.

а) To solve the equation 2/9 * x = 1.3/9, you can multiply both sides by 9 to get rid of the fractions:

2/9 * x = 1.3/9

(2/9) * 9 * x = (1.3/9) * 9

2x = 1.3

Now, divide both sides by 2 to solve for x:

2x/2 = 1.3/2

x = 1.3/2

b) To solve the equation 3/14 = x/6, you can cross-multiply to isolate x:

3 * 6 = 14 * x

18 = 14x

Now, divide both sides by 14 to solve for x:

18/14 = 14x/14

x = 9/7

c) To solve the equation 24/3 = 16/x, you can cross-multiply to isolate x:

24 * x = 3 * 16

24x = 48

Now, divide both sides by 24 to solve for x:

24x/24 = 48/24

x = 2

So, the solutions to the equations are: а) x = 1.3/2 б) x = 9/7 в) x = 2
