2 answers:
Answer:
The number of the Democrats are 14 .
Step-by-step explanation:
Let us assume that the number of Republicans are x.
As given
A committee in Congress is made up of 19 members, and there are 9 more Democrats than Republicans on it.
Thus
Number of Democrats = 9 + x
Than the equation becomes
9 + x + x = 19
9 + 2x = 19
2x = 19 - 9
2x = 10
x = 5
The number of Republicans are 5.
Thus
Number of Democrats = 9 + 5
= 14
Therefore the number of the Democrats are 14 .

For this case we have the following number written in scientific notation:
We know that this number is greater than zero because it is a positive number.
Therefore, the following statements are true:
p ∈ (-∞, ∞)
n must be between 1 and 10
n ∈ [1, 10]
