[2 + (-20)] + 3
20 x 3 = 60 20 + 3 = 23
17 and 3 = 20
the sum would be 1/4 + 3/5 = 5/20 + 12/20 = 17/20
20 x 3 = 60 (which is the same as the sum: 20 + 20 + 20 = 60)
20 = 3 + 8 + 9
3 + 17 = 20
43
The appropriate equation is: 5*(-3 + N) = -20
6*(3+20) = 138
Average = sum(X)/n = 60/3 = 20
what is 4 times the sum of a number squared and 3
