If 21x = 63y, what is the ratio of x to y expressed in simplest form? Please show work.

1 answer:

8 0

I believe these would be your steps:
21x = 63y

divide by a common factor of 7

3x = 9y

divide by a common factor of three

x = 3y is your simplest ratio

Hope this helps!

Hi!

A is FALSE - If you shrink a shape, it is not increased a shape, yet it is still dilating.

B is TRUE - When you dilate an angle, you're really just shortening or lengthening the sides, but the angle isn't changing.

C is FALSE - Explained above.

D is FALSE - Two triangles that are congruent are exactly the same, therefore if you dilate a triangle, you are changing the size so they are not the same.

E is TRUE - Similar shapes are always the same except for their size. When you dilate a shape, you only change the size, therefore they are equal in every other way and they are similar.
