mark for review (will be highlighted on the review page)

Step-by-step explanation

is / of = % / 100proportion formula

20 is what percent of 50...

20 / 50 = x / 100

cross multiply

50x = 2000

x = 2000/50

x = 40so 20 is 40% of 50

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
