Answer:
Value of x = 5
Step-by-step explanation:
Given:
x + 4 = 3(x - 2)
Find:
Value of x
Computation:
x + 4 = 3(x - 2)
⇒ x + 4 = 3x - 6
⇒ x = 3x -6 - 4
⇒ x - 3x = -10
⇒-2x = - 10
⇒ x = -10 / - 2
Value of x = 5
Martina will make flower arrangements with 3 roses in each arrangement. She will use the equation y = 3x to find the total number of roses she needs. What does x represent in the equation
X represents the number of arrangements.
Makenzie got a $30 gift certificate to the local theater for her birthday. Adult tickets (x) cost $8.00 and tickets for children (y) cost $4.50. Which inequality represents the number of adults and children who can go to a show using the $30 gift certificate?
The inequality that represents the number of adults and children who can go to a show using the $30 gift certificate is:
x < 4 and y < 7.
Where x is the number of children and y is the number of adults.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Makenzie got a $30 gift certificate to the local theater for her birthday. Adult tickets (x) cost = $8.00
Children's tickets (y) cost = $4.50
Now,
The number of children who can go to the theater.
4.50y = 30
y = 30/4.50
y = 6.67
This means,
y < 7 _____(1)
Now,
The number of adults who can go to the theater.
8x = 30
x = 30/8
x = 3,75
x < 4 ______(2)
Thus,
From (1) and (2).
The inequality represents the number of adults and children
x < 4 and y < 7.

The surface of a rectangular table has a perimeter 20 feet. Its area is 21 square feet. What are the dimensions of the table?
Answer:
7 and 3
Step-by-step explanation:
We know that all 4 sides have to add up to 20 and that 2 of the sides are the same because it's a rectangle. To find the area, we have to do length times width. Two different sides have to equal 21 when multiplied. The factors of 21 are 1, 3, 7, and 21. Let's try 1 and 21. We need an area of 21. 1 x 21 = 21 so it satisfies that. Now let's find the perimeter.21 + 21 + 1 + 1 = 44, but we need an perimeter of 20. Now, let's try 7 and 3. 7 x 3 = 21, so it satisfies the area. 7 + 3 + 7 + 3 = 20, so it also satisfies the perimeter. Therefore, 7 and 3 are the dimensions of the table.

A regular nonagon has an area of 102.4 and one side length measures 7 units long. Find the apothem. Round to the nearest tenth, if necessary.
Answer:
Apothem = 3.3 units
Step-by-step explanation:
A regular nonagon has an area of 102.4 and one side length measures 7 units long. Find the apothem. Round to the nearest tenth, if necessary.
The formula to find the area of a polygon when given Apothem and Side length =
A = 1/2 × a × p
Where p = no of sides of polygon × side length
In the above question,
We are given a polygon = nonagon = 9 sides
Side length = 7 units
p = 9 × 7 = 63 units
Area = 102.4 square units
Apothem = a = ?
We substitute into the formula
102.4 = 1/2 × a × 63
102.4 = 63a/2
Cross Multiply
102.4 × 2 = 63a
Divide both sides by 63
a = 102.4 × 2/63
a = 3.2507936508 units
Approximately to the nearest tenth = 3.3 units

A rectangular photograph is 8 cm wide and 12 cm long. The photograph is enlarged by increasing the length and width byan equal amount in order to double its area. What are the dimensions of the new photograph?
a. 12 cm by 16 cm
b. 16 cm by 24 cm
C. 20 cm by 30 cm
d. 48 cm by 72 cm
Answer:
16 cm by 24 cm
Step-by-step explanation:
Well if you want an equal amount you will have to multiply both numbers by the same thing. I used 2 and 16 cm by 24 cm would be your answer.
The dimensions of the new photograph is b. 16 cm by 24 cm.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
A rectangular photograph is 8 cm wide and 12 cm long.
The original area is
8 x 12 = 96
The photograph is enlarged by increasing the length and width by an equal amount in order to double its area.
The new area is 96 x 2 = 192
So the dimensions are b. 16 cm by 24 cm.

To find:
Why RSTU must also be a rhombus?
Solution:
We know that the opposite sides of a parallelogram are parallel and congruent.
RSTU is a parallelogram. So,
[tex]RS\parallel TU[/tex] and [tex]ST\parallel RU[/tex] [Property of parallelogram] ...(i)
[tex]RS\cong TU[/tex] and [tex]ST\cong RU[/tex] [Property of parallelogram] ...(ii)
It is given that,
[tex]ST\cong TU[/tex] ...(iii)
From (ii) and (iii), we get
[tex]RS\cong TU\cong ST\cong RU[/tex] ...(iv)
From (i) and (iv), we get RSTU is a rhombus because all sides are congruent and appositive sides are parallel.
A parallelogram with each side equal is known as rhombus.
As for the given parallelogram all the sides are equal, therefore it should be rhombus.
What is parallelogram is rhombus?Parallelogram is a closed shaped quadrilateral polygon in which opposite sides are equal and parallel and opposite angles are equal.
What is rhombus?Rhombus is a closed shaped quadrilateral polygon in which all the sides are equal and opposites sides are parallel also opposite angles are equal.
