What does -3x + 7 + -6x t 9 equal

-50x

Step-by-step explanation:

-6x times 9 which is -54x

-54x-3x = -57x

-54x+7

first quartile of this data set is 13

Step-by-step explanation:

11, 12, 13, 15, 17, 19, 22, 24, 29, 33, 38

First we find the median for the given set of numbers

Median is the middle number

11, 12, 13, 15, 17, 19, 22, 24, 29, 33, 38

19 is the median of the set of numbers

First quartile is the median of the set of numbers below 19

third quartile is the median of the set of number above 19

11, 12, 13, 15, 17

Median of 11, 12, 13, 15, 17 is 13

So first quartile of this data set is 13
