x + 12x - 45 = 0 13x - 45 = 0 13x = -45 x = - 45/13 = -3.462 (rounded)
-45, 0, 45 and 45013590
The discriminant is -199.
0/24 = 0
The question is incorrect since the mean of 45 57 0 and 3 is not 30. And the value of 45 is 45, whatever its mean when combined with other numbers. Similarly, the value of 57 is 57, whatever its mean when combined with other numbers; etc.
If you subtract 57 from 0 you get -57
199 is.
It isn't. 45-45 = 0.It isn't. 45-45 = 0.It isn't. 45-45 = 0.It isn't. 45-45 = 0.

1. Divide number by 2, record the remainder. Repeat until you reach 0. 2. Re-write the remainders from bottom to top. 3. Check TEST -> ANS -> R 57/2 -> 28 -> 1 28/2 -> 14 -> 0 14/2 -> 07 -> 0 07/2 -> 03 -> 1 03/2 -> 01 -> 1 01/2 -> 00 -> 1 57 dec = 111001 bin Check: [1] [1] [1] [0] [0] [1] (1*25)+(1*24)+(1*23)+(0*22)+(0*21) +(1*20) 32 + 16 + 8 + 0 + 0 + 1 = 57

One way is 60-60-60-60-60-60-60-57-24. Another is 60-60-60-60-60-60-60-45-36. I once saw 60-60-60-60-60-60-51-54-36.
