It is: 37+(-2)+(-65)+(-8) = -38
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
If you mean: y^2 + x^2 = 65 and y + x = 7 then the solutions are as follows:- When y = -1 then x = 8 When y = 8 then x = -1
Any multiple of 32 plus 1. 65 divided by 32 = 2 R 1
It is: 2/130 = 1/65
65+2=67 65 +2 ------ 67
1, 5, 13 and 65
1+2+3+... +65 = 65*66/2 = 65*33 = 2145 For the required sum, each term is simply double the corresponding term above, so 2+4+6+... + 130 = 2*2145 = 4290
It is: 37+(-2)+(-65)+(-8) = -38
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
If you mean: y^2 + x^2 = 65 and y + x = 7 then the solutions are as follows:- When y = -1 then x = 8 When y = 8 then x = -1
1 squared plus 8 squared or 4 squared plus 7 squared
Any multiple of 32 plus 1. 65 divided by 32 = 2 R 1
It is: 2/130 = 1/65
It is: 3/4+2/7+1/8 = 65/56
x2 - 2x + 65 = 0 Subtract 64 from each side: x2 - 2x + 1 = -64 (x - 1)2 = (i*8)2 where i is the imaginary square root of -1 x - 1 = +/- 8i x = 1 +/- 8i
45x2+35x3+65+27+40 Use P.E.M.D.A.S. 90+105+65+27+40 327 So 327 is your answer
