12x + 2 (3x - 7) - 8 please show your work

Mathematics
1 answer:
wariber [46]3 years ago
8 0

Answer:

18x - 22

Step-by-step explanation:

12x +<u> 2 (3x - 7)</u> - 8

underlined section is indicating that you need to multipy

so 2 mulitiplied by 3x is 6x

and  2 multiplied by 7 is 14

your new expression should look like this:  12x + (6x -14) - 8

now to simplify the expression you combine like terms, so combine the integers, and combine the X numbers.

so 12x and 6x = 18x

and (-14) and (-8) comes out to (-22)

this is the final answer:

18x - 22

After 8 points are added to each score in a sample, the mean is found to be M= 40. What was the value for the original mean
MArishka [77]

Answer:

The value for the original mean = 32

Step-by-step explanation:

Here, we want to calculate the original value of the mean.

Let the number of samples be n

Mathematically;

mean = Total value/n

Now, we added 8 to each of values; total value added = 8 * n = 8n

Now, for the new mean of 40; we have

(Total value + 8n)/n = 40

Total value + 8n = 40n

Total value = 40n -8n

Total value = 32n

kindly recall from the beginning of the solution;

mean = Total value/n

mean = 32n/n

mean = 32

So the original value of the mean is 32
