First you want to cross multiply. 2x+5 * 18 = 36x+90 and x * 6 = 6x. so then you would have 6x = 36x+90. now you want to sinplify. subtract 36x from both sides and you get -30x = 90. divide by -30 to get x to stand alone. x = -3

Verdich [7]

Answer:

Step-by-step explanation:

There are 10 cards total

P( not pink) = cards not pink/ total = 6 non pink cards /10 = 3/5

We replace the card so we still have 10 cards total with the same color distribution

P( yellow) = cards that are yellow /total = 1/10

Multiply the probabilities

P( not pink, yellow) = 3/5 * 1/10 = 3/50 = 6/100 = 6%
