Can you please help me with this.. you only have to do the first one (a)

Answer: $713.7

Step-by-step explanation:

First, multiply the original price by the percentage ( In this case, 549 x .30)

Now your sum is $164.7 Add that to the original price and you get your answer.

1x - 13y + 475

Step-by-step explanation:

[tex]3x \: + \: 4y \: - \: 2(4y \: - \: 8) \: - \: 25y \: + \: 485[/tex]

3x + 4y - 2x - 2 + 8y - 8 - 25y + 485

3x - 2x + 4y + 8y - 25y - 2 - 8 + 485

1x + 4y + 8y - 25y - 2 - 8 + 485

1x + 12y - 25y - 2 - 8 + 485

1x - 13y - 2 - 8 + 485

1x - 13y - 10 + 485

1x - 13y + 475

Answer:

Length is 336 in, width is 252 in

Step-by-step explanation:

Divide 588 by 7 which equals 84. Since this one-seventh, and the given ratio is  4:3, multiply 84 by 4 for the length and 84 by 3 for the width.

The length and the width of the rectangle are 28 in and 21 in, respectively.

The area of a rectangle is defined as the product of the length and width.

The area of a rectangle = L × W

Where W is the width of the rectangle and L is the length of the rectangle

Let's assume the length of the rectangle is 4x, and the width is 3x, where x is a common factor.

The area of a rectangle is given by the formula:

Area = Length × Width.

Given that the area is 588 in², we can set up the equation:

(4x)(3x) = 588

12x² = 588

Dividing both sides of the equation by 12:

x² = 588 / 12

x² = 49

Taking the square root of both sides:

x = √49

x = 7

So, x = 7.

Now we can find the length and width:

Length = 4x = 4(7) = 28 inches

Width = 3x = 3(7) = 21 inches

Therefore, the length of the rectangle is 28 inches, and the width is 21 inches.

Step-by-step explanation:

Answer:

315/8 GIVES 39.375. But 35.375 Is actually a rational number, because it is terminating after 3 decimal places.

Step-by-step explanation:

Answer:

315/8 is rational.

Step-by-step explanation:

It is rational because 315/8 = 39.375. But 35.375 Is actually a rational number because it is terminating after 3 decimal places.

Answer:

Step-by-step explanation:

Using the triangular law which states that the sum of interior anggle of a triangle is equal to exterior angle

From the diagram

Interior angles = 5x +10 and 58

Interior angle = 11x+2

Equate both expressions

5x + 10 + 58 = 11x+2

5x - 11x  = 2 - 10 - 58

-6x = 2-68

-6x = -66

x = -66/-6

x = 11

Hence the value of x is 11

Answer:

[tex]y = 4x + 36[/tex]

[tex]y = 48[/tex] when [tex]x = 3[/tex]

Step-by-step explanation:

Given

x = input

y = output

Required

Determine the equation of y

The process to get y is as follows:

Multiply x by 4: x * 4

Increase the result by 36: x * 4 + 36

Hence:

[tex]y = x * 4 + 36[/tex]

[tex]y = 4x + 36[/tex]

Solving y when x = 3

Substitute 3 for x in [tex]y = 4x + 36[/tex]

[tex]y = 4 * 3 + 36[/tex]

[tex]y = 12 + 36[/tex]

[tex]y = 48[/tex]

Answer:

[tex] {x}^{2} = {9}^{2} + {40}^{2} \\ {x}^{2} = 81 + 1600 \\ {x}^{2} = 1681 \\ x = \sqrt{1681} \\ x = 41[/tex]

Step-by-step explanation:

when you simplify 18/24 goes to 3/4 and 15/20 simplifies to 3/4 as well so they are equivalent

Answer:

105°

Step-by-step explanation:

The given angles are vertical and congruent , then

8x - 21 = 6x + 3 ( subtract 6x from both sides )

2x - 21 = 3 ( add 21 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Then

6x + 3 = 6(12) + 3 = 72 + 3 = 75°

Supplementary angles sum to 180° , thus

supplementary angle = 180° - 75° = 105°

Answer: $3.00 for 2 pounds of apples

Step-by-step explanation:

Answer:

A: 6 pounds of Apples for 9$

9/6=1.5=$1.50 per pound

Step-by-step explanation, no need to.

Step-by-step explanation:

6x - 15 = 75, 6x = 90, x = 15.

2(2x - 1) = 46, 2x - 1 = 23, x = 12.

x + (x - 10) = 26, 2x = 36, x = 18.

5x - 3x = 10, 2x = 10, x = 5.

Hence the equations

in increasing order of x-values are:

5x - 3x = 10,

2(2x - 1) = 46,

6x - 15 = 75, and

x + (x - 10) = 26.

Answer:

5x - 3x = 10

2(2x - 1) = 46

6x - 15 = 75

x+(x - 10) = 26

Answer:

First off, complementary angles are when 2 angles add up to 90 degrees. So if one angle is 82 degrees the other is 8 degrees.

Here Is Your Answer Less Than 0 But Greater Than 10

Answer:

Number of tickets sold in advance = 310

Number of tickets sold  at the door = 340

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

For the school play, the advance tickets cost $3, while tickets at the door cost $5. Thirty more tickets were sold at the door than in advance, and $2630 was collected. How many of each kind of ticket were sold?

The explation of the answer is now given as follows:

Let a represents number of tickets sold in advance. Therefore, we have:

a = number of tickets sold in advance at $3 each

a + 30 = number of tickets sold  at the door at $5 each

The total amount collected can be represented by this equation:

3a + 5(a + 30) = 2630

Solving for a, wee have:

3a + 5a + 150 = 2630

8a = 2630 - 150

8a = 2,480

a = 2,480 / 8

a = 310

Therefore, this implies:

Number of tickets sold in advance = 310

Number of tickets sold  at the door = a + 30 = 310 + 30 = 340

By the table, it seems to be that f = 1/2x
