Answer:

x = -\frac{9}{2}

Step-by-step explanation:

=> 3+2(2x+8) = 1

=> 3+4x+16 = 1

=> 4x+19 = 1

=> 4x = 1-19

=> 4x = -18

<u><em>Dividing both sides by 4</em></u>

=> x = -\frac{18}{4}

=> x = -\frac{9}{2}

Gala2k [10]
To find the probability of Joseph picking a key lime piece of taffy you will create a fraction with the number of possible outcomes over the total possible outcomes.

<u># of key lime taffies</u>              <u>12</u>
total # of taffies         =         60

12/60 = 1/5

1/5 = 0.2

Joseph has a 0.2 probability of picking a key lime taffy.

Ivenika [448]

Answer:

40% of the total was spent on fruit

Step-by-step explanation:

100%=45    x=18

100/x = 45/18    Now take the inverse of both sides

x/100 = 18/45

This leads to 1800 = 45x

1800 divided by 45 is equal to 40

The total percentage spent on fruit was 40%
