Factor-3/4 out of 3/2x-9/4y
S_A_V [24]

For this case we must factor - \frac {3} {4}of the following expression:

\frac {3} {2} x- \frac {9} {4}y

By law of signs of multiplication it is fulfilled that:

- * - = +\\- * + = -

So we have to:

- \frac {3} {4} * (- 2) = + \frac {6} {4} = + \frac {3} {2}\\- \frac {3} {4} * 3 = - \frac {9} {4}

Thus, by factoring we have:

- \frac {3} {4} (- 2x + 3y)

Answer:

- \frac {3} {4} (- 2x + 3y)

HELP ME HELP ME PLEASE
lina2011 [118]

Answer:

  11126

Step-by-step explanation:

The <em>mean</em> of a set of data is another name for its <em>average</em>. It is the sum of the data, divided by the number of numbers in the sum.

__

If you use a calculator to help you with the computation of the addition or division, you may as well use the calculator's "mean" function to do the job.

The mean of the given 6 values is their sum, divided by 6. The units of the mean are the same as those of the contributors.

  (1117 +1409 +675 +536 +1398 +1621)/6 = 6756/6 = 1126 . . . . degrees F

The mean of the data is 1126 °F.
