How do I do this?

-2(6-r)=4

To solve this, you need to isolate/get the variable "r" by itself in the equation:

-2(6 - r) = 4   Divide -2 on both sides

6 - r = -2    Subtract 6 on both sides

6 - 6 - r = -2 - 6

-r = -8       Divide -1 on both sides to get "r" by itself

    (two negative signs cancel each other out and become positive)

r = 8

PROOF

-2(6 - r) = 4    Substitute/plug in 8 into "r"

-2(6 - 8) = 4

-2(-2) = 4

4 = 4

school a:

minimum value is 2

maximum value is 22

the lower quartile is 2.5

the median is 10

the upper quartile is 15.5

school b:

minimum value is 9

maximum value is 20

the lower quartile is 12

the median is 16

the upper quartile is 18

box plot for school a isn't symmetrical. the data tails on the right

box plot for school b isn't symmetrical. the data tails on the left
