Answer:

x= -1, y= 5

Step-by-step explanation:

Please see the attached picture for the full solution.

Matrix A is called the coefficient matrix. This means that its elements are the coefficient of x and y. In matrix X, write the unknown variables. Then write the constants in matrix B.

Theorem:

[tex]{A}^{ - 1} A = I[/tex]

☆ I is an identity matrix and can be treated as 1 when multiplying.

[tex] {A}^{ - 1} = \frac{1}{ |A| } adj(A)[/tex]

☆ [tex] |A|[/tex] is the determinant of A

☆ adj(A) is the adjoint of matrix A

Answer:

the cost for the large popcorn and the small drink is $4 and $3 respectively

Step-by-step explanation:

The computation of the cost for the large popcorn and the small drink is shown below:

Let us assume the cost of the large popcorn be x

ANd, the small drink cost be y

Now as per the question

2x + 4y = $20

2x + 2y = $14

Now subtract equation 2 from equation 1

2y = $6

y = $3

Now for x it is

2x + 12 = $20

2x = $8

x = $4

Hence, the cost for the large popcorn and the small drink is $4 and $3 respectively

Answer:

n – 1,400 = 7,437

Step-by-step explanation:

A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.

Let us represent :

Weight of the mother elephant = x

Weight of the baby elephant = y

A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.

y = x - 7437 pounds

Hence,

1400 pounds = x - 7437 pounds

The weight of the mother elephant =

x = 1400 pounds + 7437 pounds

Therefore, the equation that expresses the weight of the mother where, the weight of the mother = n is:

n – 1,400 = 7,437

Answer:

<1 and <5

Step-by-step explanation:

<5 and <2 are vertically opposite. They are not complementary but they are equal

<3 is a right angle. <2 is an acute angle. They are not complementary.

<3 and <6 are both right angles. They are also vertically opposite angles and are are therefore equal. They are not complementary.

Answer: <1 and <5

<1 and 2 are complementary. <2 and <5 are vertically opposite and equal.

<1 and <5 are complementary.

Answer:

Difference in the lengths of the polygons is (x + 7) units.

Step-by-step explanation:

Lengths of the given polygon = (7x + 2) units and (6x - 5) units

Therefore, difference in the given lengths = (7x + 2) - (6x - 5)

                                                                      = (7x - 6x) + (2 + 5)

                                                                      = x + 7

Therefore, difference in the lengths of the polygons is (x + 7) units.

Answer:

x = 10

y = 50

Step-by-step explanation:

9x - 70 = x + 10

8x - 70 = 10

8x = 80

x = 10

3y - 60 = 90

3y = 150

y = 50

The answer is:

x- 10

y- 50

Answer:

Hey mate....

Step-by-step explanation:

This is ur answer......

Hint: We will multiply and divide a same number greater than 2 to both the given numbers, say 3 as 3>2. When we will multiply and divide by 3, the numbers 2 and 3 will be equivalent to 63 and 93. Now, we can easily write two rational numbers between 2 and 3.

Hope it helps!

mark me brainliest plz......

Follow me! ;)

Step-by-step explanation:

You have to multiply both numbers by 3

2*3/3 = 6/3. and 3*3/3 = 9/3

Now, we can easily write two rational numbers between 2 and 3

7/3 , 8/3

Answer: -36

Step-by-step explanation:

13, 6, -1

to get from 13 to 6 and 6 to -1, you would subtract by 7 so keep subtracting by 7 until you get 8 different terms

13, 6, -1, -8, -15, -22, -29, -36

the eighth term would be -36

i hope that makes sense

Answer:

36.9°

Step-by-step explanation:

As shown in the diagram attached,

θ is the acute angle formed at the intersection of the diagonals of the rectangle.

From the diagram,

tan(θ/2) = 10/30

tan(θ/2) = 1/3

θ/2 = tan⁻¹(1/3)

θ/2 = 18.43

Therefore,

θ = 18.43×2

θ = 36.87

θ = 36.9°

Hence the acute angle formed is 36.9°

Answer:

5

Step-by-step explanation:

(5x + 10) + 55 = 90

5x + 10 + 55 = 90

5x + 65 = 90

5x + 65 - 65 = 90 - 65 (the 65 crosses off)

5x = 25

5x/5 = 25/5

x = 5

Answer:

46.3768%

Step-by-step explanation:

Or 46.38% if you round it to the nearest tenths

The percentage decrease of songs from 69 to 37 songs is 46.4%.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The number of songs decreased from 69 songs to 37 songs.

Therefore, The net amount of songs that decreased is,

= (69 - 37).

= 32 songs.

Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,

= (32/69)×100.

= 46.4%
