For this case we must solve each of the equations proposed:
A) 
We apply distributive property to the terms within parentheses:
Subtracting 6 from both sides of the equation we have:
Dividing between -12 on both sides of the equation:
B) 
We apply distributive property to the terms within parentheses:
We add 5m on both sides of the equation:
Dividing between 2 on both sides of the equation:
C) 
We apply distributive property to the terms within parentheses:
We subtract 14 from both sides of the equation:
Dividing between -7 on both sides of the equation:
D) -
We apply distributive property to the terms within parentheses:
We add 28 to both sides of the equation:
Dividing between -21 on both sides of the equation:

Answer:
86.4
Step-by-step explanation:
72x.20= 14.4
72+14.4=86.4
I'm pretty sure this is right
The box and whisker plot is attached.
We first order the data from least to greatest:
6, 7, 11, 13, 14, 15, 15, 19, 21
The median is the middle value, or 14.
The lower quartile is the median of the lower half (split by the median). This is between 7 and 11: (7+11)/2 = 18/2 = 9
The upper quartile is the median of the upper half (split by the median). This is between 15 and 19: (15+19)/2 = 34/2 = 17
The highest value is 21.
The lowest value is 6.
We draw the middle line of the box at 14, the median. We draw the left side of the box at the lower quartile, 9. We draw the right side of the box at the upper quartile, 17. From the right side of the box, we draw a whisker to the highest value, 21. From the left side of the box, we draw a whisker to the lowest value, 6.
Answer:
(23/4, 17/4)
Step-by-step explanation:
The vector from A to B is ...
... V = B - A = (2-7, 5-4) = (-5, 1)
Point P that divides AB the way you want is 1/4 of that from A:
... P = A + (1/4)×V = (7, 4) + (-5/4, 1/4)
... P = (5 3/4, 4 1/4) = (23/4, 17/4)
