If you picked 8% of the apples on a tree, and you picked 56 apples, how many apples did the tree contain before you starting picking?

700

Step-by-step explanation:

Set up  a ratio problem.

8/100 = 56/x

8x = 5600

x = 700

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
