This recipe makes 6 portions of potato soup. Richard follows the recipe but wants to make 18 portions. Complete the amounts of each ingredient that he needs. Recipe: Serves 6 60 ml oil 80 g onions 450 g potatoes 600 ml milk

1080 ml oil

240 g onions

1350 g potatoes

1800 ml milk

Step-by-step explanation:

18 ÷ 6 = 3

every ingredient x 3

60 x 6 = 360 , 360 x 3 = 1080 ml oil

80 x 3 = 240 g onions

450 x 3 = 1350 g potatoes

600 x 3 = 1800 ml milk

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
