First you would add 2z to both sides

6k = 12 + 2z

second divide 6 from both sides

K = (12 + 2z) / 6

^^ thats your answer :)

You are at a family reunion and the cooler contains ten bottles of soda; four Sprite, three Dr. Pepper, and three Cherry Coke. T
andrew11 [14]

Answer:

<em></em>Probability = \frac{18}{1860480}<em></em>

<em></em>

Step-by-step explanation:

Given

Soda = 10

Sprite = 4

Dr. Pepper = 3

Cherry Coke = 3

Required

Determine the probability of picking Dr. pepper the fourth and fifth

First, we need to sum up the number of drinks

Total = 10 + 4 + 3 + 3

Total = 20

First Selection: Dr. Pepper

P_1= \frac{3}{20}

Since its probability without replacement;

<em>At this stage: Dr. Pepper = 2 and Total = 19</em>

Second Selection: Cherry Coke

P_2= \frac{3}{19}

<em>At this stage: Dr. Pepper = 2; Cherry Coke = 2 and Total = 18</em>

<em></em>

Third Selection: Cherry Coke

P_3= \frac{2}{18}

P_3= \frac{1}{9}

<em>At this stage: Dr. Pepper = 2; Cherry Coke = 1 and Total = 17</em>

<em></em>

Fourth Selection: Dr. Pepper

P_4= \frac{2}{17}

<em>At this stage: Dr. Pepper = 1; Cherry Coke = 1 and Total = 16</em>

<em></em>

Fifth Selection: Dr. Pepper

P_5= \frac{1}{16}

<em></em>

<em>Multiply the calculated probabilities, to give the required probability</em>

<em></em>Probability = P_1 * P_2 * P_3 * P_4 * P_5<em></em>

<em></em>Probability = \frac{3}{20} * \frac{3}{19} * \frac{1}{9} * \frac{2}{17} * \frac{1}{16}<em></em>

<em></em>Probability = \frac{3 * 3 * 1 * 2 * 1}{20 * 19 * 18 * 17 * 16}<em></em>

<em></em>Probability = \frac{18}{1860480}<em></em>

210 is equal to the total of p and 111
Aleks [24]

Answer:

p + 111 = 210

p = 99

Step-by-step explanation:

Break the question down into parts.

<u>Convert each part into algebraic form</u> (numbers or symbols).

210                                =>   210

is equal to                    =>   =

the total of p and 111    =>   p + 111

Put the equation together:

210 = p + 111

Usually, the variable is on the left side:

p + 111 = 210

<u>To solve the equation is to isolate "p"</u>. This means to keep "p" on the left, and move everything else to the right side. When moving something, do the <u>reverse operation</u> to both sides of the equation.

p + 111 = 210            "111" should be on the left. It's opposite is -111.

p + 111 - 111 = 210 - 111                Simplify. "111" cancels out on the left.

p = 99                     Solved for "p"

Kipish [7]
So it is 1.75 feet per second and you go 280 feet. 

You would do 280/1.75=x
x=160
It will take you 160 seconds to go 280 feet
It takes 160 seconds
