8, 32
Step-by-step explanation:
Hi Natalie
We have x/4 = 9
All you have to do is cross multiplication
x = 4*9
x= 36
That's all :)
I hope that's help:)
Now if you wanna check my answer just replace x by 36
36/4 = 9
9= 9
Because when you divide 36 by 4 you will find 9
I hope that's help:)
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.
