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
So the Physics book costs; $22
and the Chemistry book costs $22
- 6 = $16
we have

Step 1
Applying the distributive property in the left side ( Multiply the factors on the left side)

therefore
<u>the answer is</u>

Answer:
p=−248.125
Step-by-step explanation:
- Subtract 100 on each side of the equation.
- After this, you will have 99.25=0.4p.
- Divide each side of the equation by 0.4 to get p by itself.
- You should get p= -248.125
