The number is 49, First do 21 / 3 to find what 1/7 of the number is. We get 7, so we know 1/7 is 7 so if we do 7 x 7 we will have 7/7 or one whole and 7x7 is 49. Hope this helps
It triples in size every 4 days. In 16 days it will be 3 * 3 * 3 * 3 times bigger.
3 * 3 * 3 * 3 = 81
Therefore, after 16 days, the colony will contain (81 * 150) or 12,150 microorganisms.
100, because, x^2 - 20x + 100 = ( x - 10 )^2;
2 over 3 plus 5 equals 5 and 2 over 3
