2/3 of a box per 30 secs
2/3 times 2 = 4/3 = 1 1/3
-3x+13=16
Move +13 to the other side. Sign changes from +13 to -13.
-3x+13-13=16-13
-3x=16-13
-3x=3
Divide by -3 for both sides.
-3/-3x=3/-3
Cross out -3 and -3, divide by -3, then becomes 1*1*x=x
x=-1
Answer: x=-1
No this is true because X is on 0 so it's just X and y is on 3
<em>To get all possible permutations of these five spaces, we just multiply these numbers (that is, 8∗7∗6∗5∗4=6,720)</em>
<em>There are 6,720 five digit numbers that can be formed from the digits provided given that no digit may be repeated.</em>
<em>Hope that helped!</em>
