13x−6y=22
x=y+6
​
x=?
y=?

Answers

Answer 1

Answer:

x=-2

y=-8

Step-by-step explanation:

13x-6y=22

x=y+6

13x-6y=22

x-y=6

13x-6y=22

-6x+6y=-36 (multiplied by -6)

(13-6)x+(-6+6)y=22-36

7x=-14

x=-2

x=y+6

-2=y+6

y=-8

What is the area of the square that shares a side with the third side of the triangle?

Answers

Answer:

20 units squared

Step-by-step explanation:

Use pythagorean theorem to find third side of triangle

[tex] {2}^{2} + 4 {}^{2} = {x}^{2} [/tex]

[tex]4 + 16 = {20} [/tex]

Take the sqr root of 20

[tex] \sqrt{20} [/tex]

So the side of the square is sqr root of 20

Area is length x width

The area of a square is 2 times s, where s is the length of one side since a square sides are all equal.

So

[tex] \sqrt{20} \times \sqrt{20 } = 20[/tex]

The area of the  square that shares a side with the third side of the triangle should be considered as the 58 .

Calculation of the area of the square:

Since Two sides of a right triangle measure 7 units and 3 units.

So here the third side be

[tex]= \sqrt{7^2 + 3^2}\\\\ = \sqrt{49 + 9} \\\\= \sqrt{58}[/tex]

So here  area of the  square should be considered as 58.

A. 7 h 45 min
B. 3 h 45 min
C. 10 h 45 min
D. 5 h 45 min

Answers

Answer:

C

Step-by-step explanation:

The flight duration is 9:10 a.m. - 10:25 p.m. = 10 hours and 45 minutes. The correct option is C.

How to calculate the time?

To determine the duration of the flight, we need to calculate the time difference between the departure time from Boston and the arrival time in San Francisco, taking into account the time zone difference.

We know that San Francisco is in the Pacific time zone, which is 3 hours behind the Eastern time zone (where Boston is located). So, when it is 10:25 p.m. in Boston, it is actually 7:25 p.m. in San Francisco.

The arrival time in San Francisco is given as 6:10 a.m. San Francisco time, which is 9:10 a.m. Eastern time (since Pacific time is 3 hours behind Eastern time).

Therefore, the flight duration is:

9:10 a.m. - 10:25 p.m. = 10 hours and 45 minutes

So, the answer is C. 10 h 45 min.

if sv=38, su=26, and the perimeter of SUV is 102, what is the value of RU?


need help asap!

Answers

Answer:

38

Step-by-step explanation:

Let SUV be a triangle

Perimeter of SUV = SU+SV + UV

102 = 38 + 26 + UV

102 = 64 + UV

UV = 102 - 64

UV = 38

Hence the length of UV is 38

Barbie spent $166 on clothes. She bought some shirts that cost $14 each and some pants that cost $22 each. She bought a total of 9 items. Select the system of equations to determine how many shirts and pants Barbie purchased. Let x represent the number of shirts and y represent the number of pants.

x + y = 166

14x + 22y = 9

x + y = 166, , 14x + 22y = 9,

x + y = 9

22x + 14y = 166

x + y = 9, , 22x + 14y = 166,

x + y = 9

14x + 22y = 166

x + y = 9, , 14x + 22y = 166,

x + y = 36

166x + 9y=14x + 22y

Answers

x + y = 9 , 14x + 22y = 166

The correct system of equations will be;

⇒ x + y = 9

And, $14x + $22y = $166

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Barbie spent $166 on clothes.

The cost of each pant = $22

The cost of each shirt = $14

Total number of items = 9

Now,

Let number of shirts = x

And, The number of pants = y

Since, Total number of items = 9

So, we can formulate;

⇒ x + y = 9

And, The cost of each pant = $22

The cost of each shirt = $14

So, We can formulate;

⇒ $14x + $22y = $166

Therefore, The correct system of equations will be;

⇒ x + y = 9

And, $14x + $22y = $166
