x = 109°
3*180° - 100° - 102° - 108° - 121° = 109°
The combined time taken if Mario and Ben work together will be 1.875 days.
<u>Time taken</u>:
- Mario alone = 3 days
- Ben alone = 5 days
<u>Work rate</u> :
- Rate = 1 / time taken
- Mario's rate = 1 / 3
- Ben's rate = 1/5
<u>Their combined rate can be written thus</u> :
- Mario's rate + Ben's rate = combined rate
- 1/3 + 1/5 = 8/15
<u>Time taken if they work together</u> :
- Reciprocal of combined work rate
- Combined time taken = 1 ÷ 8/15 = 15/8 = 1.875 days
Therefore, the time taken of they work together is 1.875 days

This problem can be solved with a series of additions and subtractions.
The starting value is 500 and we first subtract 120 because on Monday they withdrew 120 dollars which leaves us with 380 dollars.
Next, we add 50 because on Wednesday they deposited 50 dollars which results in 430.
And, If I am not mistaken, we are done because when Braxton bought their basketball ticket, they used their debt card and did not withdrew from their checking account.
So, the answer is 430 dollars.

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.
