Step-by-step explanation:

QR is parallel to TU | Given

S is the midpoint of QT | Given

QS = ST | Definition of midpoint

<QSR = <TSU | definition of vertical angles

Question:

Make a list of the different arrangements that Mrs. Buchanan could use.

Answer:

[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]

Step-by-step explanation:

Given

[tex]Members = 36[/tex]

[tex]Rows\ Limit = 6[/tex]

Represent the rows with x and the column, y.

This means that:

[tex]x * y = 36[/tex]

Make y the subject:

[tex]y = \frac{36}{x}[/tex]

The list is then generated as follows:

When x = 6.

[tex]y = \frac{36}{6} = 6[/tex]

[tex](x,y) = (6,6)[/tex]

When x = 5

[tex]y = \frac{36}{5} = 7.2[/tex]

This result can not be use because the result of the number of columns must be an integer

When x = 4

[tex]y = \frac{36}{4} = 9[/tex]

[tex](x,y) = (4,9)[/tex]

When x = 3

[tex]y = \frac{36}{3} = 12[/tex]

[tex](x,y) = (3,12)[/tex]

When x = 2

[tex]y = \frac{36}{2} = 18[/tex]

[tex](x,y) = (2,18)[/tex]

When x = 1

[tex]y = \frac{36}{1} = 36[/tex]

[tex](x,y) =(1,36)[/tex]

So, the possible list is:

[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]

Answer:

12/21 or 4/7 I think

Step-by-step explanation:

Answer:

1. -39

2. -87

Step by step explanation: -39 + 9 = -30

-75 - 12 = -87

Answer and Step-by-step explanation:

For the triangles, all you have to do is subtract the two angles by 180 to find the missing angle.

2.

180 - 54 - 85 = 41

3.

180 - 36 - 59 = 85

4.

The square on the bottom represents a right angle, and right angles are always 90 degrees.

180 - 90 - 54 = 36

76 mutiply by each other

[tex] \sqrt{12} \times \sqrt{8} [/tex]

means

[tex] \sqrt{12 \times 8} [/tex]

then it will be

[tex] \sqrt{96} [/tex]

96 is not perfect square so

[tex] \sqrt{16 \times 6} [/tex]

and then

[tex] \sqrt{16} \times \sqrt{6} [/tex]

finally

[tex]4 \sqrt{6} [/tex]

is the answer

if it's helpful ❤❤❤

THANK YOU

Answer:

Explanation:

y = 90 (90 degree angle)

90 - 43 = 47, so x = 47

x = 92 because 180 - 88 = 92

x = 92 and y = 88 because 92 + 88 = 180

x = 28 because 90 - 62 = 28

x = 90 because 180 - 90 = 90

y = 85 because 42 + 53 = 95, 180 - 95 = 85

x = 133 because 180 - 47 = 133

Answer:

x = 2

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Answer:

x=-1 and y=2

Step-by-step explanation:

substitute -2x for y in 7x-8y=-23

7x-8y=-23

7x-8-2x=-23

23x=-23

x=-1

substitute -1 for x in y=-2x

y=-2x

y=(-2)(-1)

y=2

Answer:

x=-3

Step-by-step explanation:

Answer:

x = -3

Step-by-step explanation:

Plug in                

5x + 4(1 - x) = 1    

(y gets replaced by 1 - x)

Multiply                

5x + 4 - 4x = 1

(multiply 4 by whats in the parenthesis)

Combine Constants          

5x - 4x = -3

(constant = numbers without a variable)

(separate constants from variables = numbers with letters)

Combine Variables        

1x = -3

(then you got your answer and you can take the "1" off the x)
