Alex has 8 quarters six dimes and four nickels in his pocket what is the probability he will not select a quarter. How to give my the answer like 2/10

Explanation:

There are 8+6+4 = 18 coins, 18-8 = 10 of which aren't quarters.

10/18 = 5/9 is the probability of not selecting a quarter.

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
