9 + 11 = 20... 19 - 4 = 15... 15 x 20 = 300... 300 - 6 = 294 !
x-6-x-4=10-x -10=10-x -20=-x x=20 check: 20-6-20-4=10-20 -10=-10√
If you mean: x/6 +11 = 20 then the value of x is 54 Check: 54/6 +11 = 20
(5)21 x (4)11 = (5)11 x (5)10 x (4)11 = (5)10 x (5 x 4)11 = (5)10 x (20)11 =(5)10 x 20 x (20)10 = 20 x (5 x 20)10 = 20 x (100)10 = 2 x (10)1 x (10)20 =2 x (10)21 = 2,000,000,000,000,000,000,000
(23/4)/x = 11/2 (11/4)/x = 3/2 or 1/x = (3/2)*(4/11) = 6/11 x = 11/6 That is, 11/6 of two and three quarters is one and a half.
8 + 6 - 5 x 4 =8 + 6 - (5 x 4) =8 + 6 - (20) = 14 - 20 = -6
20 1 sixth of 20 = 4 (20 divided by 6) 4 x 5 = 20 (answer) :)
4/15 x 4/4 = 16/60 3/10 x 6/6 = 18/60 11/15 x 4/4 = 44/60 17/20 x 3/3 = 51/60 9/10 x 6/6 = 54/60
6+4+6+4=20 cm
5/11, you divide the 20 and the 44 by a factor that they have in common, (4)
x-6-x-4=10-x-10=10-xx=20
11 + (48/6 x 4) = 11 + 32 = 43
