Answer:
5(x+2)
Step-by-step explanation:
When factoring, always use the greatest common factor (GCF) method first. 5x and 10 have a GCF of 5, so this is applicable. Divide each factor by 5:
(5x)/5=x
10/5=2
Now, factor 5 out of 5x+10:
5(x+2)
Answer:
The value of g in the relative frequency table is 33%.
Step-by-step explanation:
We are given the following information; A 4-column table with 3 rows. The first column has no label with entries likes A, B, total. The second column is labeled C with entries 20%, 32%, 51%. The third column is labeled D with entries g, 16%, 49%. The fourth column is labeled total with entries 53%, 47%, 100%.
Representing the above information in tabular form, we get;
C D Total
A 20% g 53%
B 31% 16% 47%
Total 51% 49% 100%
Now, after seeing the whole table, it is clear that value of g is given by;
20% + g = 53%
g = 53% - 20%
g = 33%
Hence, the value of g in the relative frequency table is 33%.
Answer: Yes, the set of real numbers is closed under addition.
Explanation:
Let x and y be two real numbers. Their sum x+y is some other real number. This is what it means when we say the set of real numbers is closed under addition. Taking any two numbers and adding them will get us some other real number.
There is no way to have x+y be nonreal while x,y are both real.
