X + 12 + X - 6 = X + 50
2X + 6 = X + 50
X = 44
44 + 50 = 94
To check you can substitute X into the problem.
44 + 12 = 56
44 - 6 = 38
44 + 50 = 94
56 + 38 = 94
94 = 94
3x+5x-12=180
8x=180+12
8x=192
x=192/8
x=24
angle 1 = 5x-12
=5(24)-12
=120-12
=108
angle 2= 3x =3*24=72
angle 1 = angle 9
angle 9= 108
The answer is Letter choice C
Answer:
$27
Step-by-step explanation:
$45 * .40 (same thing as 40%)
$45 * .40 = 18 (this is how much 40% of $45 is)
$45 - 18 = $27 (you subtract 18 because it’s 40% off)
$27 (final answer)
