-3(y+3)=2y+3 what does y equal?
netineya [11]

[ Answer ]

Y = -12 / 5

[ Explanation ]


Expand:

-3y - 9 = 2y + 3


Add 9 to both sides:

-3y - 9 + 9 = 2y + 3 - 9


Simplify:

-3y = 2y + 12


Subtract 2y from both sides:

-3y - 2y = 2y + 12 - 2y


Simplify:

-5y = 12


Divide both sides by -5:

-5y / -5 = 12 / -5


Simplify:

Y = -12 / 5

What is the third quartile of this data set 20,21,24,25,28,29,35,37,39,42,44
dezoksy [38]

Answer:

The third quartile would be <u>39</u>.

Step-by-step explanation:

• Since the numbers are already in order, the next step would be to find the median:

- The <u>median</u> is the middle number; found by ordering all data points and picking out the one in the middle.

  • The median would be 29.

• The <u>first quartile</u>, is denoted as Q1 and is the middle number that falls between the smallest value of the data set and the median.

  • The first quartile would be 24.

• The <u>third quartile</u>, is denoted as Q3 and is the median of the upper half of the data set.

  • The third quartile would be 39.
