The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off and the sales tax is 8%. What is the total cost of the shopping trip?

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: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]

Step-by-step explanation:

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

Answer:

I believe it's an = 33 - 5(n - 1) or 38 - 5n they both should work

Step-by-step explanation:

I'm think that explicit formulas are like an = a1 +d(n - 1) and just replace the Variables with the correct numbers

Answer:

The answer would be the last option. y<2/3x-1

Step-by-step explanation:

The slope is 2/3 and the line crosses the y axis at -1. Since the shaded part is below the line it would make the sign less than (<)

Answer:

7=7

Step-by-step explanation:

Simplify

7+37+3  to  1010.

7x=107x=10

Divide both sides by:

77 x={10}{7}x=  ​7  ​10

Let x=10/7x=   7 10/7 -3=77×  ​7  ​10

−3=7

Cancel 7:

10-3=710−3=7

Simplify

10-310−3  to  77.

I think you meant to put an attachment but I don't see one

Step-by-step explanation:

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:

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
