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
Hey there!
ANSWER:
EXPLANATION:
To find the answer to your question, you will need to add.
First, multiply the denominator.
So the denominator will be 20.
Now move on to the numerator. Multiply 5 by 3.
Now multiply 4 bu 2.
If you want to get the numerator, add what you got after multiply.
The numerator is 23. So now let's complete the fraction.
This is your answer!
Hope this helps!
