10 lbs/$12= 1 lb/x dollars.
If you rewrite it up and down and not slanted, it would be clearer to understand, but anyways, you cross multiply:
12*1=12
12/10= 1.2
So the answer is 1.2, if you put it on that bubble sheet, put 1, then a decimal, after the decimal 2, and then all 0's,.
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]
Answer:
The following statements are correct about the number written in scientific notation:
p ∈ (-∞, ∞)
n ∈ [1, 10]
D.) x = - 9
C.) x = 0
Hope that helps, Good luck! (:
