Need the answer please thank you!

a) 4/19

b) 15/19

c) 0 (0/19)

d) 1 (19/19)

Step-by-step explanation:

In the numerator you put the number of possibilities of your happy outcome. In the denominator you put the total number of possibilities. So the bag contains 4+15=19 marbles, so that will be your denominator in each answer.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
