Draw a line from point Q to point A. Then draw another line segment from point Q to point A'. These lines are marked in red in the attached image (figure 1). Notice we have a 90 degree angle form. To go from A to A', we rotate 90 degrees counterclockwise (green angle in figure 2). Or we can rotate 270 degrees clockwise (gray angle in figure 2).
So that's why the two answers are:
choice B) 90 degrees counterclockwise
choice D) 270 degress clockwise
Side Note: the other points (B, C, and D) will follow a similar rotation path compared to point A. Either rotate those preimage points 90 degrees counterclockwise or 270 degrees clockwise so they match with their respective image points. All rotations are done around point Q.
Answer:
Let Marc's age be x. If Jeanine is twice as old as Marc, then her age will be 2x. If their ages added together are 24, then you can create the following equation:2x + x = 243x = 24x = 8Remember that x is Marc's age. So if Marc is 8, and Jeanine is twice as old, she will be 16.

Then it would go like this
|dw:1392274742487:dw|
|dw:1392274778511:dw|
|dw:1392274826374:dw|
|dw:1392274862633:dw|
The answer would be 72
Answer:
The total saving =$ 176.64
Step-by-step explanation: let Maddie's saving amount be x.
Maddie spent = $76 maddie spent in percent = 43%
We know, 43% of x = $76 or, 0.43x = $76 or, x = $76/0.43 or, x = $176.74
total savings = $176.74
