1) if b is between a and c, ab=10 and ac=28, what is the value of bc? 9 18 19 38 2) if b is between a and c, ab=6x, bc=8x and ac=42, what is the value of x? 3 14 18 24 3) if b is between a and c, ab=2x-1, bc=3x+5 and ac=24, what is the value of ab? 4 7 12 17

One

AB + BC = 28

AB = 10

10 + BC = 28

BC = 28 - 10

BC = 18

Two

AB + BC = AC

AB = 6x

BC = 8x

6x + 8x = 42

14x = 42

x = 42/14 = 3

Three

AB = 2x - 1

BC = 3x + 5

AB + BC = 24

2x - 1 + 3x + 5 = 24

5x + 4 = 24

5x = 24 - 4

5x = 20

x = 20/5

x = 4

AB = 2x - 1

AB = 2*4 - 1

AB = 7

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
