Name the property the equation illustrates.<br> (ab)3 = a (63)<br> Accociative Property of addition

Delvig [45]

<h3><u>Question:</u></h3>

Name the property the equation illustrates

(ab)3 = a(b3)

A. Commutative property of addition

B. Associative property of Multiplication

C. Associative Property of Addition

D. Inverse Property of Multiplication

<h3><u>Answer:</u></h3>

Associative property of Multiplication

<h3><u>Solution:</u></h3>

From given equation

(ab)3 = a(b3)

We have to find the property used here

We find the brackets are interchanged

So here, given is a multiplication equation

Therefore, Associative property of Multiplication is used

<h3><u>Associative property of Multiplication:</u></h3>

This property says that when we are multiplying it does not matter where you put the parenthesis

The result will be same wherever we put the parenthesis in multiplying two or more numbers

Which means,

$a \times (b \times c) = (a \times b) \times c$

Therefore, from given,

$a \times (b \times 3) = (a \times b) \times 3$

Thus associative property of multiplication is used

There are 25 students in Mrs. Venetozzi's class at the beginning of the school year, and the average number of siblings for each

Rainbow [258]

Answer:

The new class average for number of siblings is 3 5/26 or 3.1923

Step-by-step explanation:

if the average is 3 siblings per student and there are 25 students, it means that we can calculate the number of siblings

25 * 3 = 75

we add the 8 new siblings and we also add the student

75 + 8 = 83

25 + 1 = 26

To find the new average of siblings per student, we divide the number of siblings by the number of students.

83 / 26 = 3 5/26

the new class average for number of siblings is 3 5/26 or 3.1923
