Answer:
4
Step-by-step explanation:
Answer:
x = 24, PR = 404, QS = 404
Step-by-step explanation:
PR and QS are both diagonals of the rectangle. The diagonals of a rectangle bisect each other and are of equal length. Thus, we can say:
PR = QS
18x - 28 = x + 380
Solving for x, we get:
18x - x = 380 + 28
17x = 408
x = 408/17
x = 24
Thus, PR = 18(24) - 28 = 404 and QS = 24 + 380 = 404
Third choice is right.
4.5 and 3.25 gets you to 7.75, you are correct
4. 55 + 0.65*55 = $90.75
5. 90.75 * 0.25*90.75 = $113.44
6. 113.44 - 0.33*113.44 = $76.00
