Answer:
1. (B) 73
2. r = 15
Step-by-step explanation:
1. The sum of angles in a triangle is 180°.
62° +45° +k° = 180
k = 180 -107
k = 73
__
2. The sum of exterior angles of any polygon is 360°.
4r° +7r° +5r° +8r° = 360°
24r = 360 . . . . . . . . . . . . . collect terms, divide by °
r = 360/24 . . . . . divide by 24
r = 15
Answer:
it is a quadratic equation
Step-by-step explanation:
3x(3x+7) +2(3x+7)
9x square +21x +6x+14
= 9x square +27x +14
Let x = mileage
98 >= 35 + .21x
Solving for x:
98 >= 35 + .21x
63 >= .21x
300 >= x
.
This says that if the total mileage is 300 miles or less he will be within his budget.
8 + 15 = 23
23 - 65.45 = 42.46.
The rest of the people in the group split $42 and 46 cents.
Hope this helped!!
