Answer:
Step-by-step explanation:
6 is the thousands place
0 (right next to it) is the 10 thousands place
9 is the hundred thousands place. There is only 1 nine present so the answer is unique.
So the total amount of marbles is: 20+12=32
there are 20 pink marbles
20/32 = 10/16 = 5/8 (simplified)
Substitute the x with 5
-(5)2 + 4(5) - 10 = 0
That would be the number of permutations of 3 from 10.
= 10P3 = 10! / 7! = 10*9*8 = 720
