Steve has $44 in his pocket but he only has $1 and $5 bills. Write and solve a system of equations to determine how many $1 bills Steve has if he has a total of 12 bills.

he has 4, $1 dollar bills

Step-by-step explanation:

if you multiply 5 by 8 you get $40, then you add 4 $1 bills and you get

$44, if you add 8 and 4 you get 12 bills

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
