To calculate the remaining number of teams, use the sequence formula:
a(n) = a(1)Rⁿ-¹
Where a(n) and a(1) are the nth and first terms. R is the factor. Therefore, 24 teams is valid value.
After 5 rounds :
a(5) = 128*(½)⁴
a(5) = 128/16 = 8
8 teams are remained.

The base of the ladder is 6.47 feet from the house.
The value of x is 125 degrees from the given diagram
<h3>Lines and angle</h3>
Find the diagram attached
From the diagram, we can see that line l is parallel to line m, hence we can conclude that:
x = 125 degrees (The angles are corresponding angles)
Hence the value of x is 125 degrees from the given diagram

Answer:
x=5
Step-by-step explanation:
Well all i did was guess a random number from 1-10 so I could see what numbers make the equation bigger than -18 and the fist thing I guessed was 5 so this is what I did
8-6*5=-22
And them I said let me see if any multiples equal -18 so I went to for and did this
8-6*4=-16
That's when I guessed the answer if i looked at the sign correctly!
