The relationship between 1’s in the value of 911, 147, 835
shows their numerical order in the number. In which to further elaborate we
shall break down the number into its expanded form and word form:
<span><span>1. </span>900, 000,
000 = nine hundred million</span>
10, 000, 000 = ten million
1, 000, 000 = one million
100, 000 = one hundred thousand
40, 000 = forty thousand
7, 000 = seven thousand
800 = eight hundred
30 = thirty
5 = five
<span><span>2. </span><span> Nine hundred eleven million one hundred
forty-seven thousand eight hundred and thirty five. </span></span>
The sample used in this problem is classified as cluster.
<h3>How are samples classified?</h3>
Samples may be classified as:
- Convenient: Drawn from a conveniently available pool.
- Random: All the options into a hat and drawn some of them.
- Systematic: Every kth element is taken.
- Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
- Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.
For this problem, a group of schools is selected, and then the new program is applied to all students in these school, meaning that all elements in the cluster are surveyed, so cluster sampling is used.

Answer:
24
Step-by-step explanation:
6x - 9x - 5 =
combine like terms
6 - 9 = - 3
- 3x - 5 =
leave x by itself
- 3x - 5 =
+3x
___
0
- 5 = 3x
solve for x (division)
- 5 = 3x
___
3
-5/3 = x OR x = -5/3
