Just a guess! Since he was paid $8 less, it is fair to assume the CD was worth $8.
Answer:
1. c) Add/ Subtract the same quantity to/from both sides
2) Yes
Step-by-step explanation:
Answer two questions about Equations A and B:
A. 3x – 1= 7
B. Зx = 8
1) To get Equation B from Equation A we need to take the following steps
A. 3x – 1 = 7
We add one to both sides
3x - 1 + 1 = 7 + 1
3x - 0 = 8
3x = 8
Option c is the correct option.
2) We are given Equations:
A. 3x – 1= 7
B. Зx = 8
3x - 1 = 7 = 3x = 8
3x = 7 + 1 = 3x = 8
3x = 8 = 3x = 8
Therefore, we can say, Yes, Equation A is equivalent to Equation B, hence they have the same solution.
In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100.
Answer: The order may be clockwise or counterclockwise. It is preserved during these transformations: translations, dilations, and rotations. A change in the orientation of the vertices implies a change in the orientation of the figure.

Answer: $4.64
Step-by-step explanation:
The first ounce is charged at $0.79 and then every additional ounce is $0.55.
There are 8 ounces to send.
The cost will therefore be:
= Cost of first ounce + Cost of 7 additional ounces
= 0.79 + (0.55 * 7)
= 0.79 + 3.85
= $4.64
