$10.80
Step-by-step explanation:
Given:
Total number of CDs = 6
Cost price (including tax) = $71.40
Each CD had a tax of $1.10
To find the price of each CD before tax Let's first find the price of each CD after tax.
Price after tax = 
Price of each CD after tax = $11.90
Since each CD had a tax of $1.10, price of each CD before tax would be : $11.90 - $1.10 = $10.80
Therefore price of each CD before tax is $10.80
Answer:
4
Step-by-step explanation:
Firstly simplify your brackets...,
; 4(a^2 + 2b) = 4a^2 + 8b...then substitute it onto the bracket
; 4a^2 + 8b - 2b
; 4a^2 + 6b....,then substitute with the given values of a and b
; 4(2)^2)+ 6(-2)
; 16 - 12 = 4
X-5= 20
x-5= -20
Absolute value makes a negative positive, so when you are solving x-5 could have been 20 originally or -20 originally. Solve for both.
