Answer:
The set of natural numbers can be denoted as: {} (null set) because no natural number will satisfy the given equation.
Step-by-step explanation:
Given equation:

To find the set of natural numbers that satisfies the above equation.
Solution:
In order to find the set of solutions for the equation, we will solve it for 
We have:

Subtracting both sides by 8.

∴ 
Thus, we get only one solution for
that satisfies the given equation but it is not a natural number. -3 is an integer.
Set of natural numbers {1,2,3,4,5,6........}
Thus, we can say the set of natural numbers that satisfies the equation is a null set {}.
F(0)= 5 because 3(0) is the same as 0 and you add 5 so f(0)= 5
No there is no variability cause the answers will always be the same
Answer:
4 / 5 = 8 / 10
Step-by-step explanation:
4:5 is a ratio which can be rewritten as 4/5.
Any number that is multiplied by both the 4 and the 5 is an equivalent ratio to 4:5.
For example, if we multiply 2 by both sides, we have 8 to 10 which is equal to 4 to 5.
134+28= 162. So m ABC=162 degrees
