Answer:
7, Nora collected 7 shells.
Step-by-step explanation:
Xavier collected 12 shells whilist she collected 5 fewer then Xavier.
12 - 5 = 7
Therefore, Nora collected 7 shells at the beach.
2/3 divided by 1/2 equals 3/4.
So your answer would be 1/2.

Answer:
18
Step-by-step explanation:
6x5=30
2x8=16
8x1/2=4
30-16=14
14+4=18
If you are moving the center of circle 2 to the the center of circle 1, then the translation rule is (x,y) ---> (x+4, y+10).
Note how x = 1 turns into x = 5. So we add 4
Also, y = -2 turns into y = 8. We add 10
The scale factor to turn the radius r = 4 into r = 8 is 2. Basically we double the radius. We can divide the two radii to see 8/4 = 2
----------------------------------
Summary:
To go from circle 2 to circle 1, we apply these two transformations
translation: (x,y) ---> (x+4, y+10)
dilation: scale factor 2
note:
if you want to go backwards, go from circle 1 to circle 2, then undo the transformations above
The answer is (4x+3y=4 2x-7=7: 5/2 and y=-2) hope it helps and have a good day!
