Answer: 9 miles per week</h3>
Explanation:
You divide the two values given to get 63/7 = 9.
We can think of it as if it was a ratio 63 miles: 7 weeks. Dividing both parts of that ratio by 7 will turn the "7 weeks" into "1 week".
You can check the answer by multiplying the 9 miles per week with the 7 weeks to get 9*7 = 63 miles total.
Amount of money invested: P=$4,100
Interest rate percentage in decimal form: r=7.25%=7.25/100→r=0.0725
Time in years: t=8
Total money in the account at time t: A=?
A=Pe^(rt)
A=$4,100e^(0.0725*8)
A=$4,100e^0.58
A=$4,100(1.786038431)
A=$7,322.757566
A=$7,322.76
Answer: The balance in the account after 8 years is $7,322.76

So, the line that (9a+6) and 75 are sharing is straight, meaning that it is 180 degrees. Also, (9a+6) and 75 are sharing the line. Even though we don't know there exact measurements, when know that by adding them together we will get 180 degrees.
1. (9a+6) + 75 = 180
2. 9a + 81 = 180
3. 9a = 99
4. a = 11
Hope this helped!
