Beth wanted to buy vegetables. She noticed that brand A of black beans was on sale for 4 cans for 87 cents. Brand B was 3 cans for 79 cents. Which was a better buy?
A. Brand B was a better buy because those beans were 26.33 cents per can.
B. Brand A was a better buy because those beans were 21.75 cents per can.
C. Brand A was a better buy because those beans were a better brand.
D. Brand B was a better buy because 79 cents is less than brand A which was 87 cents,

b. brand a is better cause you get more for less.

Step-by-step explanation:

divide 4 by 87

then divide 3 by 79

then add 26 to 79 you will get 104 for brand b

and brand a is 87

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'.

a 270° rotation about point p says on e d g e n u it y (had to space it out because it says it's a misspelling so i couldn't submit it
