The GCF is 3.
51, 27, 84
5x+33=112x-51, deduct 5x from each side of the equation leaves 33=107x-51, add 51 to each side leaves 84=107x, divide both sides by 107 gives answer x=84/107
9 is not a factor of either one. The GCF of 51 and 84 is 3.

The Highest Common Factor (HCF) of 21 and 84 is 21. This is because 21 is a factor of both 21 and 84, and it is the largest factor that both numbers have in common. To find the HCF, you can list the factors of each number and identify the largest factor that appears in both lists.
After 84 days, three half-lives of Chromium-51 have passed. Each half-life reduces the amount of Chromium-51 by half. Thus, after three half-lives, only 1/8 (0.5^3) of the original sample will remain. Therefore, 24.0 grams * 1/8 = 3.0 grams of Chromium-51 will remain after 84 days.
Yes, the Republic F-84 Thunderjet was the main replacement for the P-51. Jet aircraft were beginning to become popular in the Air-Force around the late '40s to early '50s.
