satela [25.4K]

Answer: the price of each CD before tax is $14.9

Step-by-step explanation:

Let x represent the price of each CD before tax.

Abdul bought 3 CDs that were each the same price. It means that the total cost of the 3 CDs before tax is $3x.

Including sales tax, he paid a total of $47.40. Of that total, $2.70 was tax. It means that

3x + 2.7 = 47.4

3x = 47.4 - 2.7

3x = 44.7

x = 44.7/3

x = 14.9

the price of each CD before tax is $14.9

Solve for x 4/5 x + 4/3 = 2x
Ugo [173]

Answer:

Fraction: 10/9  mixed number: 1 1/9 decimal: 1.1

Step-by-step explanation:

1. Combine 4/5 with x

4x/5+4/3=2x

move all the terms that contain x in them to your left side of the equation

-6x/5 + 4/3 =0

subtract 4/3  from both sides

-6x/5 = 4/3

multiply both side by -5/6

-5/6 (-6x/5)= -5/6 (-4/3)

x=10/9  x=1.1  x= 1 1/9
