If 50% of a number is 20, which is 75% of what number

BRAINLIEST PLZZZ

Step-by-step explanation:

50/100 of x = 20

x = 20× 100/50

x = 20× 2

x = 40

therefore,

75/100 of 40

= 3/4 × 40

=3 × 10

= 30

hope this helps

step-by-step explanation:

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
