For every 6 students who purchase a bag of M&M’s, there are 5 students who purchase a pack of gum. Use M for the number of s

Assoli18 [71]

Answer:

M/6 = G/5

Step-by-step explanation:

We are given a relation between the numbers of students in two different groups. That relation can be used to write an equation.

<h3>Groups who bought M&Ms</h3>

If we consider M&M buyers to be 6 in a group, then the number of those groups is ...

M/6

<h3>Groups who bought gum</h3>

Similarly, the number of groups who bought gum will be ...

G/5

where there are 5 gum-buyers in each group.

<h3>Equation</h3>

The problem statement tells us that for each group of one kind, there is a matching group of the other kind. That is, the numbers of groups are equal:

M/6 = G/5

Which answer choice shows that the commutative property does not hold for matrix multiplication?

Bess [88]

Given:

The matrix statements in the options.

To find:

The answer choice that show the commutative property does not hold for matrix multiplication.

Solution:

We known that matrix multiplication is not commutative. if A and B are two non-zero matrices, then

$AB\neq BA$

Let us assume,

$A=\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\text{ and }B=\begin{bmatrix}1&3\\8&5\end{bmatrix}$

According to the above property of the matrix, we get

$\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\begin{bmatrix}1&3\\8&5\end{bmatrix}\neq \begin{bmatrix}1&3\\8&5\end{bmatrix}\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}$
