Answer:
There are 90 ways.
Step-by-step explanation:
We have ten people and we have to chose 2 of those people to be the president and vice president. So first we can chose a president, we have 10 choices for president as there are 10 people.
Now we can chose vice president but this time we only have 9 choices because we already chose a president which gives us 9 other people to chose who the vice president is.
Now we need to multiply 10 and 9 together which gives us the total amount of possible combinations for president and vice president if there are 10 people to chose from.
10*9 multiplying
= 90.
Therefore there are 90 ways for a president and a vice president to be chosen for a sorority from ten people.
28 = x + (2x - 5)
28 = 3x - 5
+5 +5
33 = 3x
/3 /3
11 = x
On number is 11, the other is 17.
