Use the Midpoint Theorem to solve for x.
The theorem states that the line between the midpoints of a triangle is half the length of the side it's opposite to.
Line BF is opposite to Line CE. Line CE has a length of 88. Therefore, we can set up the following equation:


Divide both sides by 2 to get x by itself:

The value of x is
22.
the first term is 2 and the 20th term is 1048576 .
<u>Step-by-step explanation:</u>
Here we have , If the sum of the first 12 terms of a geometric series is 8190 and the common ratio is 2. We need to Find the first term and the 20th term. Let's find out:
We know that Sum of a GP is :
⇒
So ,Sum of first 12 terms is :
⇒ 
⇒ 
⇒ 
⇒ 
Now , nth term of a GP is
⇒ 
So , 20th term is :
⇒ 
⇒ 
⇒ 
Therefore , the first term is 2 and the 20th term is 1048576 .
Let x = number of adult tickets
Let 2x = number of student tickets.
So, x + 2x = 336
3x = 336
x = 112
They sold 112 adult tickets.
187=190
186=190 because 18.7 and 18.6 are 187 and 186 so 8 is the tenth place. So they both equal 190
