Answer:
Step-by-step explanation:
Consecutive interior angles are supplementary:
(6x +6)° +(3x -15)° = 180°
9x -9 = 180 . . . . . . . . . . . . . . simplify, divide by °
x -1 = 20 . . . . . . . . . . . . divide by 9
x = 21
__
Angles of a linear pair are supplementary:
(3x -15)° +(y +18)° = 180°
3(21) -15 + y + 18 = 180 . . . . substitute for x, divide by °
y = 114 . . . . . . . . . . . . . . . . . . subtract 66

The distance between any two points is the <em>absolute value of their difference</em>. Only one of those expressions provided represents the difference between -7 and 16; the others alter the numbers in one way or another. Which one of those absolute value expressions contains the <em>difference of -7 and 16</em>?
28 = k - 12
28 + 12 = k
40 = k
