Evelyn is making a candy that contains 25% dark chocolate and the rest milk chocolate. the candy has 3 pounds of milk chocolate.

part a: write an equation using one variable that can be used to find the total number of pounds of dark chocolate and milk chocolate in the candy. define the variable used in the equation and solve the equation. hint: 0.25x represents the number of pounds of dark chocolate in the candy. (5 points)

part b: how many pounds of dark chocolate are present in the candy? show your work. (5 points)

The sum of the percentages of milk and dark chocolate needs to equal 100%.

Since dark chocolate is 25%, then milk chocolate must be 75%

Now we can set up a proportion:

75% = 3 lbs

25% = X lbs

Dark chocolate =  (3 x 25%) / (75% x X) = 1 lb

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'.
