Its 16.
So you have 12 miles on that trail, and markers every 2/3 of the way there. If you were to divide 2 with 3 then you can get the decimal of the fraction. Which in this case it’s 0.75. So every single 0.75 of the mile there is a marker. Divide 12 with 0.75 and you get 16 markers.
Hoped this helped in some way.
A= 4 B= 2 C= -1
follow the formula ax^2 + bx + c= 0.
3x4x1/2= 6inches Multiply the base by the height and after multiply by one half
You would multiply by the reciprocal (flip the fraction)
5/3 * 24 = 40
b = 40
Use photo math , I’m sure it will help
