Answer:
Step-by-step explanation:
(8-2)*180=1080 degrees
114+66+94+259+94+67+254+97+x=1080
1045+x=1080
1080-1045=x
x=35

We have 15 ways to chose 2 students for the position of president and Vice President
<em><u>Solution:</u></em>
Given that,
There are 6 students. 2 of them are chosen for the position of president and Vice President.
<em><u>To find: number of ways we have to choose the students from the 6 students</u></em>
So now we have 6 students, out of which we have to choose 2 students
As we just have to select the students. We can use combinations here.
In combinations, to pick "r" items from "n" items, there will be
ways

<em><u>Then, here we have to pick 2 out of 6:</u></em>
Total students = n = 6
students to be selected = r = 2

Thus we have 15 ways to chose 2 students for the position of president and Vice President

Answer:
C) Van: 9, Bus: 25
Step-by-step explanation:
6V + 2B = 104
V + 2B = 59
V = 59 - 2B
6(59 - 2B) + 2B = 104
354 - 12B + 2B = 104
10B = 250
B = 25
V = 59 - 2(25)
V = 59 - 50
V = 9
