Answer:
when a number is divisible by 9, then the number is divisible by 3.
Step-by-step explanation:
They tell us "When a number is divisible by 9, the number is divisible by 3" we could change it by:
when a number is divisible by 9, then the number is divisible by 3.
Which makes sense because the number 9 is a multiple of the number 3, which means that the 9 can be divided by 3, therefore, if the number can be divided by 9, in the same way it can be divided by 3 .
The statement "When a number is divisible by 9, the number is divisible by 3" can be rewritten in if-then form as: If a number is divisible by 9, then the number is divisible by 3.
In this case, the conclusion is that the number is divisible by 3.
Here is a table that summarizes the if-then form of the statement:
| Hypothesis | Conclusion |
|---|---|---|
| A number is divisible by 9 | The number is divisible by 3 |
In other words, if the hypothesis is true (i.e., the number is divisible by 9), then the conclusion must also be true (i.e., the number is divisible by 3).
Here is an example:
Hypothesis: The number 18 is divisible by 9.
Conclusion: The number 18 is divisible by 3.
Both the hypothesis and the conclusion are true, so the if-then statement is true.

Answer:
D
Step-by-step explanation:
Step-by-step explanation:
The greatest common factor (GCF) of 27 and 45 is 9.
27 + 45
9 (3 + 5)
9 (8)
72
The expression 27 + 45 is rewritten using the Greatest Common Factor (GCF) and the distributive property as 9*(3 + 5) = 72.
The given expression is 27 + 45. To rewrite this using the Greatest Common Factor (GCF) and the distributive property, we first find the GCF of the two numbers. The GCF of 27 and 45 is 9. We then divide each number by the GCF and rewrite the expression using the distributive property.
So, 27 + 45 = 9*(3 + 5) = 9*8 = 72.
The above step is the application of the distributive property, where a*(b + c) = ab + ac.
