What is the value of n. 6(x – 1) = 9(x + 2)

Answer:

x=−8

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    6*(x-1)-(9*(x+2))=0

(6 • (x - 1)) -  9 • (x + 2)  = 0

6 • (x - 1) -  9 • (x + 2)  = 0

Pull out like factors :

-3x - 24  =   -3 • (x + 8)

-3 • (x + 8)  = 0

Solve :    -3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solve  :    x+8 = 0

Subtract  8  from both sides of the equation :

  x = -8

6(x-1) = 9(x+2)

Use distributive property on both sides:

6x-6 = 9x + 18

Subtract 6x from both sides:

-6 = 3x + 18

Subtract 18 from both sides:

-24 = 3x

Divide both sides by 3:

X = -8

OLEGan [10]

Answer:

The given statement is false.

Step-by-step explanation:

Circle graphs, or pie graphs, show information over a period of time.

This statement is false.

A circle graph, or a pie chart, helps in visualizing information and data. These graphs are used to show the results in a proportional manner.

The circle graph is divided in proportions that show the percentage of a certain answer.

If 15 actuators have failed today, what is the probability that a) at least 10 are repairable? b) from 3 to 8 are repairable? c)
Ann [662]

The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

According to the statement

we have given that If 15 actuators have failed and we have to find the probabilities on some conditions.

we know that the formula of probabilities is

probability = possible outcomes / total outcomes

So,

  • at least 10 are repairable = 1 - (10 are not repairable)

at least 10 are repairable = 1 - 10/15

at least 10 are repairable = (15 - 10)/15

at least 10 are repairable = (5)/15

at least 10 are repairable = 1/3

  • from 3 to 8 are repairable = 3/15 *8/15

from 3 to 8 are repairable = 1/5 *8/15

  • exactly 5 are repairable = 5/15

exactly 5 are repairable = 1/3

These are the probabilities of the given conditions.

So, The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.
