A shade of green paint is to be mixed with 3 parts blue and 2 parts yellow. Ten gallons of green paint are to be mixed. How many gallons of yellow paint must be used?
04
02
05
06 and 2/3

4 gallons

Step-by-step explanation:

3 parts blue and 2 parts yellow

total of 5 parts

10 gallons with 2 of 5 parts yellow

10 * 2/5 = 4

4 gallons

ok so 3 blues and 2 yellows make 1 so we just multiply the 2 yellows by ten so 20 gallons of yellow

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'.
