x = 9

Step-by-step explanation:

(3x-20)/9 = 56/72

72(3x-20) = 9(56)

216x-1440 = 504

add 1440 to each side

216x = 1944

divide both sides by 216

x = 9

9

Step-by-step explanation:

If you draw a segment parallel to a side of triangle that intersects two sides of the triangle, that segment divides the intersected sides into segments of proportional lengths.

9/72 = (3x - 20)/56

1/8 = (3x - 20)/56

3x - 20 = 1/8 * 56

3x - 20 = 7

3x = 27

x = 9

9

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
