Answer:

Step-by-step explanation:
We have been given an equation
. We are asked to solve our given equation.
First of all, we will add
on both sides of equation to separate x variable on one side of equation.


Now, we will make a common denominator.


Add numerators:


Upon multiply both sides of our equation by
, we will get:



Therefore, the solution for our given equation is
.
First is yes
Second is no
Third is no
Fourth is no
Answer:
First find what the sale price of the CD is. 30% off means the CD is selling for 70% of the original cost ( 100%-30% = 70%)
Multiply the original cost by 70%:
17.00 x 0.70 = $11.90 ( sale price)
Now you need to multiply the sale price by the tax percentage to find the amount of tax:
11.90 x 0.08 = 0.95 ( tax)
Now add the sale price and the tax for the total cost:
11.90 + 0.95 = $12.85

Hello there.
Question: <span>Jayden wants to solve the equation n + 67 = 81. He writes the equation n + 67 - 67 = 81 - 67 to find the value of n. Will Jayden get the correct answer using this equation?
Answer: n + 67 - 67.
In this part of the equation the 67 would cancel out.
Which leaves n = 81 - 67.
This would get the correct answer to the equation.
Solving the equation meant that he would have to subtract 67 from both sides.
Which he has done.
Solving the equation:
81 - 67 = 14
n = 14.
