What are the values of m and n in the matrix addition below?

Aleksandr [31]

ANSWER

The correct answer is $m=45,n=12$ .

EXPLANATION

We were given the matrix equation;

$\left[\begin{array}{cc}n-1&6\\-19&m+3\end{array}\right] +\left[\begin{array}{cc}-1&0\\16&-8\end{array}\right] =\left[\begin{array}{cc}10&6\\-3&40\end{array}\right]$ .

We must first simplify the Left Hand Side of the equation by adding corresponding entries.

$\left[\begin{array}{cc}n-1+-1&6+0\\-19+16&m+3-8\end{array}\right]=\left[\begin{array}{cc}10&6\\-3&40\end{array}\right]$ .

That is;

$\left[\begin{array}{cc}n-2&6\\-3&m-5\end{array}\right]=\left[\begin{array}{cc}10&6\\-3&40\end{array}\right]$ .

Since the two matrices are equal, their corresponding entries are also equal. we equate corresponding entries and solve for m and n.

This implies that;

$n-2=10$

We got this equation from row one-column one entry of both matrices.

$n=12$

Also, the row three-column three entries of both matrices will give us the equation;

$m-5=40$

$m=45$

Hence the correct answer is $m=45,n=12$ .

The correct option is option 2

Use decimals to answer the question what is 6% of 225

ElenaW [278]

Answer:

13.5

Step-by-step explanation:

(Are you meaning this as the answer is a decimal?)

3/50 * 225/1

Cross-cancel 50 and 225 by cancelling out 25.

3/2 * 9/1

Rewrite this so it is a single fraction.

(3 * 9)/2

Multiply 3 by 9 to get 27.

27/2

Divide 27 by 2 to get 13.5.

13.5

6% of 225 is 13.5.

Kobotan [32]

Answer:

90,60,75,135,30,0,180

Step-by-step explanation:

Given : Chris has decided to triple the amount of time he spends studying each night

To Find: . If the data set that represents the number of minutes he had previously spent studying each night is 30, 20, 25, 45, 10, 0, 60, which data sets represents the number of minutes he will now spend studying.

Solution:

Previous Hours : 30,20,25, 45, 10, 0, 60

Now since she decided to triple the amount of time she spends :

So,

30*3=90

20*3=60

25*3=75

45*3=135

10*3=30

0*3=0

60*3=180

So, the new set of data is 90,60,75,135,30,0,180
