N is equal to 2.5
I divided 20 by 5 to get 4. = 20 ÷ 5 = 4. So, I divide 10 by 4 to get n. = 10 ÷ 4 = 2.5
Or we can do this solution.
20 5
---- = ---- ; do cross multiplication. 20n = 10(5)
10 n
20n = 50 ; to get n, divide both sides by 20. 20n / 20 = 50 / 20 = n = 2.50
Whichever way: 20/10 = 5/2.5
I believe it is C, as integer numbers cannot be expressed as a fraction for any integers.
Answer:
Step-by-step explanation:
The exterior angle in a triangle is equal to the sum of the interior opposite angles in a triangle
Therefore,
Now solve for x
Now let's solve for the exterior angle
Hope this helps you.

I’m pretty sure the equation is 28-f=n
and the answer is 2.
This is a geometric sequence of the form:
a(n)=(x+3)(-2x)^(n-1) because each term is -2x times the previous term...so
a(8)=(x+3)(-128x^7)
a(8)=-128x^8-384x^7
