Kyle has a bag of red, green, and blue marbles. He asks Linda to draw a marble without looking in the bag, record its color, and replace it. She draws 20 times with these results: 7 red marbles, 9 green marbles, and 4 blue marbles. What is the experimental probability of drawing a red marble? Write your answer as a fraction (in simplest form), decimal, and percent.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
