6 0

Answer:

y = -2.25

Step-by-step explanation:

-8(3y+5) = 14

-8(3y+5)/-8 = 14/-8

3y+5 = -1.75

3y+5-5 = -1.75-5

3y = -6.75

3y/3 = -6.75/3

y = -2.25

PLEASE HELP!!!!

Answer:

The probability that you would choose a green candy: \frac{45}{139} or approximately 32%.

Step-by-step explanation:

The general form of probability can be calculated as the following fraction:

\frac{number of desired outcomes}{total number of outcomes}

First, to find the total number of outcomes, you need to add all of the candies together:  42 + 45 + 20 + 32 = 139, so there are 139 total outcomes.  Since there are a total of 45 green candies, the probability of choosing green from the total can be written as:  

\frac{45}{139}

Dividing the numerator by the denominator and multiplying by 100 gives us the percentage of approximately 32%.
