Answer:

11) x = 9

12) x = 9

Step-by-step explanation:

11) Corresponding segments are proportional, so ...

x/6 = 12/8

x = 6(12)/8 . . . multiply by 6

x = 9

12) Similar triangle relationships show you the geometric mean relationship that applies in this case.

long side/short side = x/3 = 27/x

x² = 3·27 . . . . . . cross multiply

x = √(3·27) . . . . geometric mean relationship

x = 9

A particular chemistry book costs $6 less than a particular physics book, while two such chemistry books and three such physics

sladkih [1.3K]

Answer:

Step-by-step explanation:

Let's say the Physics book costs $x

The Chemistry book will cost $x - $6

Two such Chemistry books will cost;

2($x - $6) = $(2x - 12)

Three such Physics books cost $3x

$(2x - 12) + $3x = $123

$5x - $12 = $123

$5x = $111

x = $22 $\frac{1}{5}$

So the Physics book costs; $22 $\frac{1}{5}$

and the Chemistry book costs $22 $\frac{1}{5}$ - 6 = $16 $\frac{1}{5}$
