Answer:
7+7+7+6+4+2=33
Each friend will have to pay $11
Step-by-step explanation:
The modes are 9 and 11
(-3, -6)
add the total time = 3+1 = 4 hours
add total miles = 100+49 = 149
divide 149 by 4= 149/4 = 37.25 miles per hour average
Because the angles are vertical angles, they must be equal.
3x + 7 = 112
3x = 105
x = 35
Check
3(35) + 7 = 112
112 = 112 Correct
