Evan buys 2 CDs. $1.49 is added to the total price which is the 5% sales tax. What is the cost for each of the CDs?

Answers

In the given question, there are several information's that are of great importance. It is by using these information's the correct answer can be determined. It is already given that the amount of sales tax is $1.49 and the percentage of sales tax is 5%. Now it is important to firstly determine the total price of 2 CDs and then determine the price of 1 CD.
Let us assume that the cost of 2 CDs = x
Then
5x/100 = 1.49
5x = 1.49 * 100
5x = 149
x = 149/5
   = 29.8
So the cost of 2 CDs is $29.8.
Now
The cost of each CD = (29.8/2) dollars
                                   = 14.9 dollars
So the cost of each CD is $14.9.

What’s the answer to
5+3x=7(x+3)

Answers

Answer:

-4

Step-by-step explanation:

Simplifying

5 + 3x = 7(x + 3)

Reorder the terms:

5 + 3x = 7(3 + x)

5 + 3x = (3 * 7 + x * 7)

5 + 3x = (21 + 7x)

Solving

5 + 3x = 21 + 7x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7x' to each side of the equation.

5 + 3x + -7x = 21 + 7x + -7x

Combine like terms: 3x + -7x = -4x

5 + -4x = 21 + 7x + -7x

Combine like terms: 7x + -7x = 0

5 + -4x = 21 + 0

5 + -4x = 21

Add '-5' to each side of the equation.

5 + -5 + -4x = 21 + -5

Combine like terms: 5 + -5 = 0

0 + -4x = 21 + -5

-4x = 21 + -5

Combine like terms: 21 + -5 = 16

-4x = 16

Divide each side by '-4'.

x = -4

Simplifying

x = -4

How to simplify

(-0.75x+6)-(2.5x-1.9)

Answers

Multiply x and 0.75
Multiply x and 1
The x just gets copied along.
The answer is x
x
0.75*x evaluates to 0.75x
Because of the minus sign
0.75x becomes - 0.75x
The answer is -0.75x
-0.75*x+6 evaluates to -0.75x+6
Multiply x and 2.5

2.5*x evaluates to 2.5x
2.5*x-1.9 evaluates to 2.5x-1.9
To subtract the polynomials -0.75x+6 and 2.5x-1.9 we try to subtract terms in one polynomialwith any like terms in the other polynomial.
Be very careful with the "-" sign in front of 2.5x-1.9 it is to be used on all terms in it.
-0.75x - 2.5x = -3.25x
6 - -1.9 = 7.9
The answer is -3.25x+7.9
(-0.75*x+6)-(2.5*x-1.9) evaluates to -3.25x+7.9
