Solve by making a proportion. A teacher grades 27 students' essays in 3 hours. How many essays can she grade in 8 hours if she spends the same amount of time grading each essay?

72

Step-by-step explanation:

27/3 = 9

9 * 8 = 72

Your answer would be 72.

Step-by-step explanation:

Because 27 divided by 3 would equal 9. Then you would multiply 9 by 8, which is 72.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
