X + 12 = 20
x + 12 -12 = 20 -12
x = 8
60 x 50 = 3000 meters.......
Y=3x+6
y=mx+b 3 is slope and m is also the slope, six is b because it’s where it BEgins :)
.48x =36 x=36/.48 x=75 So the total distance to kirk's grandmother's house was 75 miles
Answer:
option 3, 45
Step-by-step explanation:
3x - 9° + 30° + 24° = 180° (angle sum property of a triangle)
3x - 9° + 54° = 180°
3x + 45° = 180°
3x = 180° - 45°
3x = 135°
x = 135/3
x = 45°
therefore, option 3 is the correct option
