360. 18 = 2 x 32 8 = 23 10 = 2 x 5 lcm = 23 x 32 x 5 = 360
Positive integer multiples of 23 which lie between 400 and 499 are: 23 x 18 = 414 23 x 19 = 437 23 x 20 = 460 23 x 21 = 483
3x + 5 = 6x + 23 -3x = 18 x = -6
3 with 5 remaining 23 - 5 = 18 = 6 x 3
6. 42 = 2 x 3 x 7 18 = 2 x 32 72 = 23 x 32 hcf = 2 x 3 = 6
1800. 200 = 23 x 52 18 = 2 x 32 lcm = 23 x 32 x 52 = 1800
360. 18 = 2 x 32 8 = 23 10 = 2 x 5 lcm = 23 x 32 x 5 = 360

2 x 3 x 3 = 18 2 x 2 x 2 x 3 = 24
6 + 6 + 6 (or 6 x 3) = 18 18 + 5 = 23 The answer is 23.
3x + 5 = 6x + 23 -3x = 18 x = -6
i got x = 1.35 12x+18=41-5x +5x 17x+18=41 -18 17x=23 /17 x=1.35
3 x 9 = 27 20 x 9 = 180 total 207
3 with 5 remaining 23 - 5 = 18 = 6 x 3
The molar mass of water is approximately 18 grams/mol. So, one water molecule has a mass of 18/6.022 x 10^23 grams. Therefore, the mass of 1.5 x 10^23 water molecules would be 18 x 1.5 x 10^23/6.022 x 10^23 grams.
The geometric mean of 18 and 30 is approximately 23. 2379 (√(18 x 30) = √540).
