Answer:
Step-by-step explanation:
Vertical angles are congruent.
8x = 2x +30
6x = 30 . . . . . . subtract 2x
x = 5 . . . . . . . . divide by 6
__
60y -40 = 40y +20
20y = 60 . . . . add 40-40y
y = 3 . . . . . . . .divide by 20
_____
<em>Check</em>
The 'x' angles are 8x° = 8·5° = 40°.
The 'y' angles are (40y+20)° = (40·3+20)° = 140°.
The angles are supplementary, as they are supposed to be.

Step-by-step explanation:
Ariel will always have some money remaining.
We can demonstrate this by designing a table.
Each week she starts with a certain amount. At the end of the week she deducts 10 %, and the amount remaining becomes the starting amount for the next week.
<u>Week</u> <u>Principal</u> <u>Less 10 %</u> <u>Remaining
</u>
1 600.00 60.00 540.00
2 540.00 54.00 486.00
3 486.00 48.60 437.40
4 437.40 43.74 393.66
5 393.66 39.37 354.28
6 354.28 35.43 318.85
7 318.85 31.89 286.97
8 286.97 28.70 258.27
9 258.27 25.83 232.44
10 232.44 23.24 209.20
Ariel will still have $209.20 in her account after 10 weeks.
