Answer 1

Answer:

see explanation

Step-by-step explanation:

(3)

The opposite sides of a parallelogram are congruent, so

6x = 3x + 15 ( subtract 3x from both sides )

3x = 15 ( divide both sides by 3 )

x = 5

and

2y - 10 = y + 5 ( subtract 5 from both sides )

y - 10 = 5 ( add 10 to both sides )

y = 15

Then x = 5 and y = 15

-------------------------------------------------------------------------

(4)

The diagonals of a parallelogram bisect each other, thus

y = 4x - 6 → (1)

9x - 25 = 2y → (2)

Substitute y = 4x - 6 into (2)

9x - 25 = 2(4x - 6)

9x - 25 = 8x - 12 ( subtract 8x from both sides )

x - 25 = - 12 ( add 25 to both sides )

x = 13

Substitute x = 13 into (1)

y = 4(13) - 6 = 52 - 6 = 46

Then x = 13 and y = 46

A function rule takes an input(x) and coverts into an output(y), by increasing 4 times the inpuy by 36. Write an equation for the rule and determine the output for this rule when the input is 3

Answers

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]

Answers

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

i’ll give you all my points that i have and rate you good if you answer these three questions before 3:00pm est. if f(x)=8-5x, find each value. one is f(4c), the second question is f(2-k), and the third is f(4p+3)

Answers

Ok so to start you plug in what’s in the parentheses for x

4c=8-5(4c)
2-k=8-5(2-k)
4p+3=8-5(4p+3)

In the first one you distribute the -5
4c=8-20c
Then add 20c to both sides
24c=8
And divide by 24
C=8/24 or 1/3

Distributing the -5 on the second one gets you
2-k=8-10+5k
Then you combine like terms
2-k=-2+5k
Subtract 5k from both sides
2-6k=-2
Subtract 2 from both sides
-6k=-4
Divide by -6
K=4/6 or 2/3

and lastly the equation is 4p+3=8-5(4p+3)

So you distribute -5
4p+3=8-20p-15
Combine like terms
4p+3=-20p-7
Add 20p to both sides
24p+3=-7
Subtract 3 from both sides
24p=-10
And then divide by 24
P= -10/24 or -5/12

The area of a rectangle is 588 in^2. The ratio of the length to the width is 4:3. Find the length and the width

Answers

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.

What is the area of the rectangle?

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.

Answers

Answer:

x =11

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

Vertical Angles: Find the Supplementary Angles (photo provided)

Answers

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°

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

Answers

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
