Ronna needs 20.5 pints of blueberries to make jam. She picked 7.75 pints on Friday and 4,25 pints on Saturday, Hon many more pints does she need to pick?

8.5 I believe

Step-by-step explanation:

7 + 4 = 11

.75 + .25 = 1

11 + 1 = 12

20.5

- 12 .0

8 . 5

is there a picture

step-by-step explanation:

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'.
