1) x≥6

--------------------------------------

--------------------------------------

2) h  > 20

Mark worked more than 20 hours.

Step-by-step explanation:

1) -20x+18≥-102

-20x≥-102-18

-20x≥-120

Dividing -20 both side

≥

x≥6

--------------------------------------

--------------------------------------

2) 14h + 25 > 305

14h  > 305-25

14h  > 280

Dividing 14 both side

h  > 20

Mark worked more than 20 hours.

-20x >= -120

x < or = 6

14h > 280

h > 20
