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.

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.
