Answer:
15
Step-by-step explanation:
We assume your "natural numbers" are <em>positive integers</em>. (Some authors also include zero.)
n(B) = 5
n(U) = 20
n(B') = 20 -5 = 15
Answer:
Step-by-step explanation:
6(6p-9)-10p-6(6p-9)-10p
36p-54-10p-36p+54-10p
36p-36p-54+54-10p= -10p
Answer:
32-3n
Step-by-step explanation:
The formula for the nth term of a sequence is ' a+(n-1)d ' where a is the first term and d is the difference.
Here, a is 35 and d is -3.
a+(n+1)d
35+(n+1)(-3)
35-3n-3
32-3n
Pure water is a chemical compound. Every water molecule is
one oxygen atom tightly bound to 2 hydrogen atoms. That's a
big part of the reason why the chemical formula for water is H₂O .
