x + 10 = 18 18 - 10 = x 18 -10 = 8 x = 8
-8 + 10x = 18 10x = 18+8 10x = 26 x = 26/10 x = 2.6
18
Remainder Theorem:- When f(x) is divided by (x-a) the remainder is f(a) Tor example:- f(x) x3-2x2+5x+8 divided by x-2 f(2) 8-8+10+8 = 18 So the remainder is 18 if there is no remainder then the divisor is a factor of the dividend.
If: x+7-4x+1 = -10 Then: 8-3x = -10 And: -3x = -10-8 => -3x = -18 So: x = -18/-3 => x = 6
x + 10 = 18 18 - 10 = x 18 -10 = 8 x = 8
864 = 6 x 8 x 18
7/8 of 18 = (7 x 18)/8 = 126/8 = 15.75 or 1/8 of 18 = 18/8 = 2.25 2.25 x 7 = 15.75
2.25 x 8 = 18
-8 + 10x = 18 10x = 18+8 10x = 26 x = 26/10 x = 2.6
18 = 9 x 2, so LCM of 18 & 9 is 18. 8 = 2 x 2 x 2; so 18 & 8 share a common factor of 2, so the LCM = 18 x 2 x 2 = 72.
8-8x=8x+18 Through simple algebra, this can be manipulated to solve for x: 8=16x+18 -10=16x -5/8=x
8 x 9 = 72 18 x 4 = 72
(18 x 9) - (19 x 8) = 10
an the answer is 144
8% of 18= 8% * 18= 0.08 * 18= 1.44
18 x 18 = 324 1/8 x 18 = 2.25
