Answer:
2
Step-by-step explanation:
x + 2y = 14
2y = -x + 14
y = -1/2 x + 7
m = -1/2
product of slopes is -1
so perpendicular slope is 2
D is the diameter of the wheel
the circle is π.d = 180
so d = 180/π = 57 cm

They stop at the same time after 4 times for the southbound bus to return and five times for the northbound bus returns to the bus stop
2x/3-6=4. 2x/3=4+6. 2x/3=10. 2x=10*3. 2x=30. X=30/2. x=15.
