1 Russian ruble is equivalent to <span>0.01742 U.S. dollars.
Therefore, to find how much US dollars is equivalent to </span><span>327,317.28 Russian rubles, all you have to do is cross multiplication as follows:
amount = (</span>327,317.28 * 0.01742) / 1
amount = 5701.867018 US dollars
The number is 6. The equation would be 8x - 12 = 36. You add over the 12 to the 36 to get 48. Then when you do 8x divided by 48, you get x = 6. Therefore, the number the problem is asking for is 6.
