Mia spends 45 minutes reading each day. She does 2/5 of her reading at school. How many minutes does Mia spend reading at school?

18 minutes

Step-by-step explanation:

1. 45 minutes is the TOTAL amount she reads so it can be expressed as x/45

*x=a part

2. set up a proportion

x/45 = 2/5

3. now solve by either cross multiplication or finding a scale factor. I am finding a scale factor because that is easiest.

45/5=9

so 5 * 9 = 45

so 2 * 9 = 18

the asnwer is 18. I hope this helps

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'.
