Well let's do some maths
let's set this into a slope intercept for
where the function is equal to y
2y= 5 - 3x
dividing both sides by 2 would get you
y = 5/2 -3/2x
the slope in this case
would be
-3/2
not -2/3
For this case we have that, by definition of trigonometric relationships of rectangular triangles, the cosine of an angle is given by the division of the leg adjacent to the angle on the hypotenuse of the triangle. According to the figure we have:
Thus, the value of x is 9.3
Answer:
Three runners will be needed. 1/3 is .3 and 1/9 is .1 since they all need to do 1/9 of a mile that makes the answer 3.
The answer would be 8/12 because it is adding 1/12 + 7/12
