The questions is asking which one and i say is graph B
a)
FH = 102, FG = 5x + 9. HG = 9x - 5 <em>Given</em>
FG + HG = FH <em>Segment addition postulate</em>
5x + 9 + 9x - 5 = 102 <em>Substitution</em>
14x + 4 = 102 <em>Simplify (added like terms)</em>
14x = 98 <em>Subtraction property of equality</em>
x = 7 <em>Division property of equality</em>
b) FG = 5x + 9 = 5(7) + 9 = 35 + 9 = 44
c) HG = 9x - 5 = 9(7) - 5 = 63 - 5 = 58
Answers: a = 7, b = 44, c = 58
Let B = the weight of box B
Let 2B = the weight of box A
Let 2B + 30 = the weight of box C
B + 2B + 2B + 30 = 640
5B = 610
B = 122 pounds, weight of box B
2B = 2(122) = 244 pounds, weight of box A
2B + 30 = 2(122) + 30 = 274 pounds, weight of box C
hope this helps
You can figure the remaining percentage in 2050 and calculate using that, or you can figure the amount of population that will be lost and subtract that from the 2006 value.
<u>First method</u>: The remaining population will be 100% - 5.8% = 94.2% of that in 2006. 0.942×40.2 million ≈ 37.9 million
<u>Second method</u>: 5.8% of 40.2 million is about 2.3 million, so the remaining population will be 40.2 - 2.3 = 37.9 million
