Answer:
There was 62.23% change in radius as the ion formed.
Step-by-step explanation:
Given
Radius of Aluminium
atom = 143 pm
Radius of Aluminium
atom = 54 pm
Change is the radius = Radius of Aluminium
atom - Radius of Aluminium
atom = 143 -54 = 89
Now to find % Change is the radius we will divide Change is the radius by Radius of Aluminium
atom and multiply by 100 we get
% Change is the radius = 
Hence there was 62.23% change in radius as the ion formed.

60% markup means 60 percent of 90 dollars added back into the price
45 is 60 percent of 90 dollars so you would add that to $90
I believe the answer is 2, because if you divide 2.0 by 1 you get 2 and if you divide each row you get 2
Step-by-step explanation:
1st) Distribute 8 with x and 8 with -1 which will give you
8x-8=5x-35
2nd) Use opposite operation and add 8 both sides
8x-8=5x-35
+8 +8
---------------
8x=5x-27
3rd) subtract 5x from both sides
8x=5x-27
-5x= -5x
_______
3x=-27
4th) Divide 3 from both sides so -27 by 3
3x=-27
