What type of problem can be modeled and solved with a 2-variable linear inequality?

use formula for the circle a=3.14

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

probability for j is 1/4

while

a is 1/6

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed
