Since there is no condition whatsoever for this arrangement, I can consider the 2 digits and the 5 letters as 7 different objects.

Total permutation (with no repetition):
7 chosen among 7 , that is 7 ! = 5040 arrangements

Total permutation (WITH REPERTITION):

7⁷ = 823 543

\frac{1}{3} (n + 15) = -2

First, replace the numerator with the parentheses.
\frac{n+15}{3} =-2
Second, multiply both sides by 3.
n + 15 = -2 * 3
Third, multiply 2 × 3 to get 6.
n + 15 = -6
Fourth, take away 15 from each side.
n = -6 - 15
Fifth, simplify -6 - 15 to get -21.
n = -21

Answer: n = -21

The seats at a local baseball stadium are arranged so that each row has 5 more seat than the row in front of it. If there are fo
ohaa [14]
You would do an arithmetic sequence
use A1 +(n-1)d to calculate number of seats in the last row

An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119 seats in the last row

now use a sum sequence to find total number of seats

Sn = n(a1 + an)/2 
Sn = 24(4+119)/2 
Sn = 24(123) /2 
Sn = 1476 total seats
