Сколько будет 2020*5*42*754*389

124 420 405 200

Пошаговое объяснение:

622 102 026 000

Пошаговое объяснение:

2020*5 = 10100

10100 * 5 = 50500

50500 * 42 = 2 121 000

2 121 000 * 754 = 1 599 234 000

1 599 234 000 * 389 = 622 102 026 000

Пошаговое объяснение:

8x + 12 = x + 9

8x - x = 9 - 12

7x = -3

x = -3 : 7

x = -3/7

===========

15c - 7 = c - 6

15c - c = 7 - 6

14c = 1

x = 1 : 14

c = 1/14

==========

62 - 13x = 18x

-13x - 18x = -62

-31c = -62

c = 62 : 31

c = 2

=============

6x + 18 = 5 - x

6x + x = 5 - 18

7x = -13

x = -13 : 7

x = -1 6/7

===============

19 - 5n = 7 + 3n

-5n - 3n = 7 - 19

-8n = -12

n = 12 : 8

n = 1,5

============

51x + 41 = 45 - 51x

51x + 51x = 45 - 41

102x = 4

x = 4 : 102

x = 2/51

=========

=========

1/2x - 13 = 3/4x + 7

1/2x - 3/4x = 7 + 13

2/4x - 3/4x = 20

-1/4x = 20

x = -20 : 1/4

x = -80

=================

2/3c - 1,5 = 1/6c + 3,5

2/3c - 1/6c = 3,5 + 1,5

4/6c - 1/6c = 5

1/2c = 5

c = 5 : 1/2

c = 10
