The sum of 2n, for n= 0 to 29.
2/3 + 1 + 3/5 - 3/10 = 59/30 or 1 and 29/30
11x + 29
1 + 30 + 2 + 3 + 5 + 6 + 10 + 15 = 72
2/3 + 3/10 = 29/30
1+12=13+15=28+2=30+29=59.
30! 29
The sum of 2n, for n= 0 to 29.
2/3 + 1 + 3/5 - 3/10 = 59/30 or 1 and 29/30
Times 2, plus 30 = 88.
11x + 29
6x - 1 = 29 => 6x = 30 => x = 5 Then x2 + x = 25 + 5 = 30
1 + 30 + 2 + 3 + 5 + 6 + 10 + 15 = 72
2d+1=29 2d=29-1=28 d=28/2=14
2/3 + 3/10 = 29/30
1/2 + 1/15 = 15/30 + 2/30 = 17/30
30. 2+3+5=10, 4+6=10, and 2+4+1+1+2=10.
