Answer:
B(7,10)
Step-by-step explanation:

Answer:
35 degrees
Step-by-step explanation:
90 -55 = 35
You start by doing 65.20 (the bill) divided by 5 (the amount of people paying)
65.20 / 5 = 13.04
Then you add 13.04 (how much each person paid towards the bill) and 2.75 (the amount of money each person left as a tip)
13.04 + 2.75 = 15.79
Each person paid $15.79
To solve this problem, you must set it up like this : 6/x = 15/100
Now, cross-multiply. 15x = 600
Divide by 15 on each side.
x=40.
6 is 15% of 40.
Hope this helps :)
