for what value of x do the expressions 2/3x+2 and 4/3x+6 have the same value?

9514 1404 393

Answer:

  x = -6

Step-by-step explanation:

To find the desired value of x, set the expressions equal.

  2/3x +2 = 4/3x +6

Subtract 2/3x +6 from both sides.

  -4 = 2/3x

Multiply by the inverse of the coefficient of x.

  (3/2)(-4) = x = -6

The value of x that makes the expressions have the same value is -6.

__

Check

  2/3x +2 = 2/3(-6) +2 = -4 +2 = -2

  4/3x +6 = (4/3)(-6) +6 = -8 +6 = -2 . . . . same value

Which method correctly solves the equation using the distributive property?

Negative 0.2 (x minus 4) = negative 1.7
Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x minus 4 = negative 1.7. Negative 0.2 x = 2.3. x = negative 11.5.
Negative 0.2 (x minus 4) = negative 1.7. x minus 4 = 0.34. x = 4.34.
Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x + 0.8 = negative 1.7. Negative 0.2 x = negative 2.5. x = 12.5.
Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x minus 0.8 = negative 1.7. Negative 0.2 x = negative 0.9. x = 4.5.

Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in her science book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.

Book Mean Median Mean Absolute Deviation
Art 68.7 50 15.4
Science 54.2 55 7.9


She claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. Based on the data, is this a valid inference? (10 points)

Yes, because the mean is larger in the art book
No, because the mean is larger in the art book
Yes, because there is a lot of variability in the art book data
No, because there is a lot of variability in the art book data
