please help me solve this

Answer:

k = 5

Step-by-step explanation:

Since the equation is y = kx and x equals 3 while y equals 15, in order to solve this equation we are going to have to substitute the variables with their answers:

x = 3

y = 15

15 = 3k

Now we divide 3 from both 3x and 15 to segregate the variable x:

15/3 = 3k/3

5 = k

Now to check our work we are going to substitute 5 for the variable k, 3 for the variable x and 15 for the variable y.

y = kx

15= (5)(3)

15 = 15

Tada, I hope this helps you!

Answer:

k=5

Step-by-step explanation:

y=kx     Also meaning   y = k times x

x=3      y=15      

y divided by x   = 15 divided by 3 = 5

k=5

Lets Check Our Work

y=kx

15=?3

? times 3 is 15  = 5

Answer:

y = 62

Step-by-step explanation:

Since we need to solve for x first, we'll solve the left triangle first. A triangle equals 180 degrees, so with in mind:

x + 7 + 3x - 18 + x - 9 = 180

add like terms

5x - 20 = 180

add 20 to both sides

5x = 200

divide by 5

x = 40

Now we have x, input it into the equations for the second triangles:

x + 21 + x + 17 + y = 180

40 + 21 + 40 + 17 + y = 180

add/simplify

118 + y = 180

subtract 118 from both sides

y = 62

Answer:

x = 40° ; y = 62°

Step-by-step explanation:

The figure consists of 2 triangles. According to Angle sum property in a triangle , sum of measure of all the angles of a traingle is equal to 180° .

So ,

[tex](3x - 18) + (x + 7) + (x - 9) = 180[/tex]

[tex] = > 5x - 20 = 180[/tex]

[tex] = > 5x = 180 + 20 = 200[/tex]

[tex] = > x = \frac{200}{5} = 40[/tex]

Now using the angle sum property in another triangle ,

[tex](x + 21) + (x + 17) + y = 180[/tex]

[tex] = > y + (40 + 21) + (40 + 17) = 180[/tex]

[tex] = > y + 61 + 57 = 180[/tex]

[tex] = > y + 118 = 180[/tex]

[tex] = > y = 180 - 118 = 62[/tex]

Answer:

y=10 when x=7

Step-by-step explanation:

y=2x-4

y=10

Substitute y with "10": 10=2x-4

Add 4 on both sides: 14=2x

x=7

Answer:

substitute 10 for y in the equation y=2x-4

10=2x-4

2x=10+4

2x=6

divide both side by 2

x=3

Answer:10 inches

Step-by-step explanation: 4+4+1+1=10The perimeter of a rectangle is the sum total length of all of its sides.[1] A rectangle is defined as a quadrilateral, or a geometric shape with four sides. In a rectangle, both sets of opposite sides are congruent, meaning that they are the same length.[2] While not all rectangles are squares, all squares can be considered rectangles, and a compound shape may be composed of rectangles.[3]

it's so easy just do

18÷1/3=54 which is easir if you think it like 18×3=54

Answer:

54

Step-by-step explanation:

For every liter of sports drink, there is 3 players. You can use this problem to solve it y = 3x  or now  54 = 3(18). Simply it is 3 * 18 is 54. 3 is from 3 people per liter.

Answer:

We know that the circumcenter of a right triangle is at the center of the hypotenuse.

Thus, the circumcenter of a triangle is: C(-1, 1/2)

Please check the attached figure.

Step-by-step explanation:

Given the triangle with the coordinates of the vertices

First plot the points on the graph, as shown in the attached diagram.

It is clear from the attached diagram that it forms a right triangle.

From the attached diagram, it is clear that the center of the hypotenuse lies on C(-1, 1/2).

Thus, the circumcenter of a triangle is: C(-1, 1/2)

Please check the attached figure.

The lateral surface area of the triangular prism is

Explanation:

The side lengths of the base of the triangular prism are 5 meters, 8 meters, and 10 meters.

It is given that the height of the prism is 16.5 meters.

To determine the lateral surface area of the prism, let us use the formula

LSA =  (a + b + c)h

where a, b,c are the side lengths of the base of the triangular prism and h is the height of the prism.

Here: a = 5, b = 10,c = 8 and: h = 16.5

Substituting these values in the formula, we have,

LSA = (5 + 10 + 8) 16.5

Simplifying, we get,

LSA = (23) 16.5

Multiplying, we get,

LSA = 379.5

Thus, the lateral surface area of the triangular prism is,

379.5sq. units
