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
Rewrite the decimal number as a fraction with 1 in the denominator
0.225=0.22510.225=0.2251
Multiplying by 1 to eliminate 3 decimal places, we multiply top and bottom by 103 = 1000
0.2251×10001000=2251000
X+y/3=5
equals x+y=15 because of the division sign "/"
equals 14.5+14.5=15
x=14.5
