did the test and got it right

The augmented matrix represents the situation is given as, [tex]\begin{bmatrix}6 & 2 | & 618 \\1 & 1 |& 165 \\\end{bmatrix}[/tex]. Then the correct option is B.

A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.

Let x be the number of the adults and y be the number of the children.

Adults were charged $6, and children were charged $2.

The total amount of money collected was $618.

6x + 2y = 618

A total of 165 people attended the opening night of a school play.

x + y = 165

The equation can be written in the form of matrix form. Then

[tex]\begin{bmatrix}6 & 2 | & 618 \\1 & 1 |& 165 \\\end{bmatrix}[/tex]

Then the correct option is B.

Step-by-step explanation:

(x+3)=10

10 - 3 = 7

Answer:

(2,24) (1,18) (3,30) (4,36)

Step-by-step explanation:

Answer:

x = 3

x = (-1)/2

x = 13/4

Step-by-step explanation:

Solve for x:

(2 x)/3 + 15 = 17

Put each term in (2 x)/3 + 15 over the common denominator 3: (2 x)/3 + 15 = (2 x)/3 + 45/3:

(2 x)/3 + 45/3 = 17

(2 x)/3 + 45/3 = (2 x + 45)/3:

1/3 (2 x + 45) = 17

Multiply both sides of (2 x + 45)/3 = 17 by 3:

(3 (2 x + 45))/3 = 3×17

(3 (2 x + 45))/3 = 3/3×(2 x + 45) = 2 x + 45:

2 x + 45 = 3×17

3×17 = 51:

2 x + 45 = 51

Subtract 45 from both sides:

2 x + (45 - 45) = 51 - 45

45 - 45 = 0:

2 x = 51 - 45

51 - 45 = 6:

2 x = 6

Divide both sides of 2 x = 6 by 2:

(2 x)/2 = 6/2

2/2 = 1:

x = 6/2

The gcd of 6 and 2 is 2, so 6/2 = (2×3)/(2×1) = 2/2×3 = 3:

Answer:  x = 3

______________________________________________________

Solve for x:

3 x - x + 8 = 7

Grouping like terms, 3 x - x + 8 = (3 x - x) + 8:

(3 x - x) + 8 = 7

3 x - x = 2 x:

2 x + 8 = 7

Subtract 8 from both sides:

2 x + (8 - 8) = 7 - 8

8 - 8 = 0:

2 x = 7 - 8

7 - 8 = -1:

2 x = -1

Divide both sides of 2 x = -1 by 2:

(2 x)/2 = (-1)/2

2/2 = 1:

Answer: x = (-1)/2

_______________________________________

Solve for x:

4 (2 x - 6) = 2

Divide both sides of 4 (2 x - 6) = 2 by 4:

(4 (2 x - 6))/4 = 2/4

4/4 = 1:

2 x - 6 = 2/4

The gcd of 2 and 4 is 2, so 2/4 = (2×1)/(2×2) = 2/2×1/2 = 1/2:

2 x - 6 = 1/2

Add 6 to both sides:

2 x + (6 - 6) = 1/2 + 6

6 - 6 = 0:

2 x = 1/2 + 6

Put 1/2 + 6 over the common denominator 2. 1/2 + 6 = 1/2 + (2×6)/2:

2 x = 1/2 + (2×6)/2

2×6 = 12:

2 x = 1/2 + 12/2

1/2 + 12/2 = (1 + 12)/2:

2 x = (1 + 12)/2

1 + 12 = 13:

2 x = 13/2

Divide both sides by 2:

x = (13/2)/2

2×2 = 4:

Answer: x = 13/4

angle Q = 64

We know that supplementary angle = 180

Now,

angle P + angle Q = 180

now put the value and solve the equation ok!

The correct option will be option C: Multiply/divide both sides by the same non-zero constant.

Step-1: we have to balance each side by simplifying the equation

Step-2: add/subtract constant term on both sides of the equation to separate variable and constant term on both sides

Step-3: divide the coefficient of the variables on both sides.

So according to the question,

the given equations are:

AAA: 3(x+2)=18

BBB: x+2=6

We have to find a way from equation AAA to Equation BBB

from the above equation, it is clear BBB is factor AAA.

to get BBB from equation AAA, we have to just divide 3 on both sides of the equation AAA.

Therefore option C will be correct as 3 is a non-zero constant. we have to divide both sides by this same non-zero constant.

Therefore The correct option will be option C: Multiply/divide both sides by the same non-zero constant.

[tex]Reduction = \$3300[/tex]

Step-by-step explanation:

Given

[tex]Pay\ for\ 52\ weeks = \$55,640[/tex]

Required

Determine the reduction when paid is reduced to 49 weeks

First, we need to determine the weekly pay

[tex]Weekly\ Pay = \frac{\$55,640}{52}[/tex]

[tex]Weekly\ Pay = \$1070[/tex]

Next, is to determine the pay for 49 weeks;

[tex]Pay = Weekly\ Pay * 49[/tex]

[tex]Pay = \$1070 * 49[/tex]

[tex]Pay = \$52430[/tex]

Subtract the 49 week pay from 52 weeks pay to get the payment reduction;

[tex]Reduction = \$55640 - \$52340[/tex]

[tex]Reduction = \$3300[/tex]

Step-by-step explanation:

40 + 65 = 105

315/105 = 3

The number of hours for both the trains to be at 315 miles apart is 3 hours

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first train be = A

Let the second train be = B

The average speed of train A = 40 miles per hour

The average speed of train B = 65 miles per hour

Since , the two trains are moving in opposite directions , their speed are added

The total average speed of train A and train B =
( average speed of train A  + average speed of train B )

The total average speed of train A and train B = 40 + 65

                                                                             = 105 miles per hour

Total distance = 315 miles

The equation is

So , the time taken for the two trains to be at 315 miles apart is

Time = Distance / Speed

        = 315 / 105

        = 3 hours

Hence ,

The number of hours for both the trains to be at 315 miles apart is 3 hours

The value of the number is -9/10.

Let the number be x

Two times the quantity of eight times a number plus two will be written as:

= 2(8 × x) + 2

= 2(8x) + 2 = 16x + 2

Three times the quantity of two times the same number minus 7 will be written as:

= 3(2 × x) - 7

= 3(2x) - 7 = 6x - 7

We will equate both values and this will be:

16x + 2 = 6x - 7

Collect like terms

16x - 6x = -2 - 7

10x = -9

x = -9/10

In conclusion, the value of the number is -9/10.
