An athlete is planning to run a certain distance in three days. • The first day, he is planning to run 1/3 • The second day, he wants to run 3/4 the distance. The distance left. • The last day, he plans to run the last 4 miles. Part A: Create an equation that represents the situation and can be used to solve for x, the total distance that the athlete is x s planning to run in the three days. Enter your equation in the first response box. Part B: Enter the total distance, in miles, that the athlete is planning to run in the three days in the second response box.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
