barxatty [35]

Answer:

-3/4, -2/5, -4/15

Step-by-step explanation:

using calculator, -3/4 = -0.75, -4/15 = -0.266666..., -2/5 = -0.40

imagine that -0.75, -0.26... and -0.40 are temperatures

the coolest temperature is -0.75, the warmest one is -0.26...

so the least number is -0.75, greater -0.40 and the greatest -0.26...

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 $\frac{1}{5}$
