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 $\frac{1}{5}$

GarryVolchara [31]

Answer:

4, see below :)

Step-by-step explanation:

We can rewrite the equation into:

3.5 + 2 - 1.5

First we add 3.5 and 2

3 and 2 are in the ones place so:

5, and then you added the .5

5.5

Then:

5.5 - 1.5

First we subtract the tenths place so:

.5 - .5 = 0

Then the ones:

5 - 1 = 4
