Answer:
1. First option.
2. First option.
3. First option.
Step-by-step explanation:
1. You need to remember that the Associative Property of Addition states the following:
[tex](a+b)+c=a+(b+c)[/tex]
Notice that you can group the numbers "a", "b" and "c" in any combination.
In this case, given the statement provided in the exercise:
[tex](2 + 3.4) + 6 = 2 + (3.4 + 6)[/tex]
You can identify that it ilustrates the Associative Property of Addition.
2. Remember that:
- Natural numbers are known as "Counting numbers".
- Whole numbers include positive numbers and zero.
- Integers include the Whole numbers and the negative numbers.
- Rational numbers are those numbers that can be wriitten as a fraction:
[tex]\frac{a}{b}[/tex]
Where "a" is the numerator and "b" is the denominator.
- Integers are a subset of Rational Numbers.
- Irrational numbers cannot be written as a fraction.
Based on this, you can conclude that [tex]\frac{1}{3}[/tex] is a Rational number.
3. The product is the result of a multiplication.
In this case the word "more than" indicates Addition.
Then, the product of 2 more than "y" and 7 can be expressed as:
[tex]7(y+2)[/tex]
