22+2x = 37+6+x 2x-x = 37+6-22 x = 21
22237 + 37 = 7474 + 74 = 148148 + 74 = 222 = 37 x 6
Sum(X) = 37 Sum(X2) = 289 Var(X) = Sum(X2) - sum(X)2/n = 289 - 37*37/5 = 15.20
-42 + 37 - (6 x 9) + (7/4) = -57.25
37 x 27 = 999
LCM = 1332 prime factorization of: 36 = 6 x 6 37 = ----------37 ========= LCM=6 x 6 x 37 = 1332
2x - 6 = x - 43 2x = x - 37 x = -37
22+2x = 37+6+x 2x-x = 37+6-22 x = 21
This equation can't actually be factored, but you can solve for x: 6x2 + 37x + 6 = 0 ∴ 6x2 + 37x = -6 ∴ x2 + (37/6)x = -1 ∴ x2 + (37/6)x + (37/12)2 = -1 - (37/12)2 ∴ (x + 37/12)2 = -1 - (37/12)2 ∴ x + 37/12 = ±[-1 - (37/12)2]1/2 ∴ x = 37/12 ±[-1 - (37/12)2]1/2 Which gives you two complex numbers for the answer, approximately: 37 / 12 + 3.2414417 × i 37 / 12 - 3.2414417 × i
22237 + 37 = 7474 + 74 = 148148 + 74 = 222 = 37 x 6
5/6 of 37 = 30 and 5/6 5/6 x 37 = 185/6 The decimal value is about 30.833
x = 6
Let x be the varible: 7x-5 = 37 7x = 37+5 7x = 42 x = 6
6x - 6 < 31 6x < 37 x < 37/6
60 x 6 = 360 397 - 360 = 37 Answer: 6 hours 37 minutes
2 x 3 x 37 = 222 1, 2, 3, 6, 37, 74, 111, 222
Well, assuming you mean that there are 37 possible numbers you'd follow this method: c = 37 x (37-1) x(37-2) x (37-3) x ... (37-(n-1)) where c is the number of combinations and n is the number of numbers drawn. For example: if n = 6 then: c = 37 x 36 x 35 x 34 x 33 x 32 = 1673844480 combinations. There's normal a button on your calculator that'll do this for you.
