Помогите 36 задание найдите решение уравнений только чётные!!!

Answer 1

Пошаговое объяснение:

№2

1,25х = 40

х = 40 : 1,25

х = 32

№4

3 2/11х = 35

х = 35 : 3 2/11

х = 35 : 35/11

х = 35 * 11/35

х = 1 * 11/1

х = 11/1

х = 11

№6

8 5/13х = 4 5/26

х = 4 5/26 : 8 5/13

х = 109/26 : 109/13

х = 109/26 * 13/109

х = 1/2 * 1/1

х = 1/2

Answer 2

Ответ:

2)

$x = 32$

4)

$x = 11$

6)

$x = \frac{1}{2}$

8)

$x = 45$

10)

$x = 0.12$

12)

$x = 0.071$

Пошаговое объяснение:

2)

$1.25x = 40$

$x = 40 \div 1.25$

$x = 32$

4)

$3 \frac{2}{11} x = 35$

$\frac{35}{11} x = 35$

$\frac{x}{11} = 1$

$x = 11$

6)

$8 \frac{5}{13} x = 4 \frac{5}{26}$

6)

$8 \frac{5}{13} x = 4 \frac{5}{26}$

$\frac{109}{13} x = \frac{109}{26}$

$\frac{x}{13} = \frac{1}{26}$

$x = \frac{13}{26}$

$x = \frac{1}{2}$

8)

$315.9 \div x = 7.02$

$315.9 = 7.02x$

$7.02x = 315.9$

$x = 315.9 \div 7.02$

$x = 45$

10)

$27 \frac{7}{12} \div x = 3.31$

$\frac{331}{12} \div x = 3.31$

$x = \frac{3.31 \times 12}{331}$

$x = \frac{39.72}{331}$

$x = 0.12$

12)

$2.64 \div x = 37$

$2.64 = 37x$

$37x = 2.64$

$x = 2.64 \div 37$

$x = 0.071$
