Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. he spent a total of $47.65. if hugh bought 3 magazines, how many books did he buy? the equation that models the problem is 3.95m + 8.95b = 47.65, where m is the number of magazines and b is the number of books.

i just took the test, the correct answer is .. 31.5 in.

step-by-step explanation:

b. is true. hope this . happy

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
