Answer 1

Explicação passo-a-passo:

1)

5800 16

x 30

16 . x = 5800 . 30

16x = 174000

x = 174000/16

x = 10875

2)

4 3

x 21

3 . x = 4 . 21

3x = 84

x = 84/3

x = 28

3)

4 30

5 x

5 . x = 4 . 30

5 . x = 120

x = 120

5

x = 24

4)

27 72

x 192

72 . x = 27 . 192

72x = 5184

x = 5184/72

x = 72

5)

2 0,8

z 12

0,8 . z = 2 . 12

0,8z = 24

z = 24/0,8

z = 30

6)

45 280

30 x

30 . x = 45 . 280

30 . x = 12600

x = 12600

30

x = 420

7)

80 21

120 x

120 . x = 80 . 21

120 . x = 1680

x = 1680

120

x = 14

8)

300 15

3600 x

300 . x = 3600 . 15

300x = 54000

x = 54000/300

x = 180

x = 3h

9)

400 6

800 x

800 . x = 400 . 6

800 . x = 2400

x = 2400

800

x = 3

10)

80 300

50 x

50 . x = 80 . 300

50 . x = 24000

x = 24000

50

x = 480

11)

750 25

1250 x

1250 . x = 750 . 25

1250 . x = 18750

x = 18750

1250

x = 15
