FootnoteYou can use your computers calculator to answer questions like this. Also, many search engines like Bing or Google can perform some fairly complex calculations or unit conversions.If x = 8, then 23 -x - 9 = 23 - 8 - 9 = 6
9 x 28 = (9 x 20) + (9 x 8) 9 x 20 = 180 9 x 8 = 72 180 + 72 = 252 9 x 28 = 252
8 x (9 - 3) 4^2 (9 - 3) - 4^2 12-4^2 4 x 8 =32
If: 8+x = 17 Then: x = 9
(8 - x) / 6 = 98 - x = 54x = 8 - 54x = -46OR8 - (x/6) = 98 = x/6 + 9x/6 = 8 - 9 = 1x = 6
If x = 8, then 23 -x - 9 = 23 - 8 - 9 = 6
The answer is '72'. However, learn your '8' times table and your '9' times table. of multipolication. 8 times 8 x 1 = 8 8 x 2 = 16 8 x 3 = 24 8 x 4 = 32 8 x 5 = 40 8 x 6 = 48 8 x 7 = 56 8 x 8 = 64 ( 8^2 ; 8 squared) 8 x 9 = 72 ( as answered) 8 x 10 = 80 8 x 11 - 88 8 x 12 = 96 And 9 times 9 x 1 = 9 9 x 2 = 18 9 x 3 = 27 9 x 4 = 36 9 x 5 = 45 9x 6 = 54 9 x 7 = 63 9 x 8 = 72 ( as answered) 9 x 9 = 81 ( 9^2 ; 9 squared) 9 x 10 = 90 9 x 11 = 99 9 x 12 = 108
x + 9 = 8 Therefore, x = 8 - 9 x = -1
9 x 8! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1So, 9 x 8! = 9! = 362,800
9 * -8 - 8 = - 72 - 8 = - 80

If you mean: x+8-x+9 when x = 5 Then it is: 5+8-5+9 = 17
8 is twice as big as 4. 9 x 8 is twice as big as 9 x 4.
7/8 x 8/9 = 7/9
Since 8 is 2 x 4, 9 x 8 is 2 x 9 x 4
72 = 6 x 12 = 8 x 9 = 9 x 8
