Ramen purchase a box of candy for himself on the way back to the dorm he ate 2/3 of the candy while he was putting away grocerie
Aleksandr [31]

Answer:

12 chocolates

Step-by-step explanation:

Represent the original number of chocolates by c.  

Then (1/4)(2/3)c = 2

Solving this for c, we multiply both sides by 4:  (2/3)c = 8

and then multiply both sides by (3/2):  c = (3/2)(8) = 12

Originally the box contained 12 chocolates.

What is the image of (9,3) after a dilation by a scale factor of 3 centered at the<br> origin?
sergiy2304 [10]

Answer:  (27, 9)

Multiply the original coordinates by the scale factor 3 to get this answer

9*3 = 27

3*3 = 9

This only works if the center of dilation is the origin.

The general rule is (x,y) \to (kx, ky) where k is the scale factor.
