1. 'x' = -18/4
2. 'x' = -4/3
The equations are Not Equivalent.
1. Linear Equation :An equation between two variables that gives a straight line when plotted on a graph. Or we can say,
A linear equation is defined as an equation that is written in the form of Ax+By=C. It is the combination of two variables and a constant value present in them.
We have given
(x/3) - 2 = (5x/3) + 3
(5x/3) - (x/3) = -2 - 3
4x/3 = -6
4x = -6 × 3
x = -18/4
In first equation we got the value of x is -18/4.
2. Equivalent to Linear Equation :Two systems of linear equations are equivalent if and only if they have the same set of solutions.
To determine the equivalent of linear equation,
First, we need to find the value of "x" for each equation. If "x" is the same for both equations, then they are equivalent. If "x" is different then the equations are not equivalent.
We have equation
x(x + 1) = (x + 2)²
x² + x = x² + 4 + 4x
(We have solved (x + 2)² by using algebraic identity (a + b)² = a² + b² + 2ab.)
4x - x = x²- x² - 4
3x = -4
x = -4/3
In the second equation we got the value of x is -4/3.
Hence, as we can see it clearly that the value of x is not same in both equations so this is Not Equivalent.

Admission to a baseball game is $4.00 for general admission and $6.50 for reserved seats. The receipts were $4589.50 for 988 paid admissions. How many of each ticket were sold?
There were 733 general tickets sold and 255 reserved tickets.
How to calculate the values?Let the general admission = g
Let the reserved seats = r
Therefore, the appropriate equation will be:
g + r = 988
4g + 6.5r = 4589.50
From equation i r = 988 - g
4g + 6.5r = 4589.50
4g + 6.5(988 - g) = 4589.50
4g + 6422 - 6.5g = 4589.50
6.5g - 4g = 6422 - 4589.50
2.5g = 1832.50
g = 1832.50/2.5
g = 733
Since g + r = 988
r = 988 - 733
r = 255
Therefore, there were 733 general tickets sold and 255 reserved tickets.

If the stylist needs to
b.
make 20 oz of dye, how much of each dye color is needed?
If the stylist needs to make 100 oz of dye, how much of each dye color is needed?
The answers to both the questions are as follows:
We need 3 ounces of red tone, 6 ounces of gray tone, and 5 ounces of a brown tone to make 20 ounces of dye.We need 15 ounces of red tone, 30 ounces of gray tone, and 25 ounces of a brown tone to make 100 ounces of dye.The quantity of specific hair dye produced by given ingredients are:
= 1(1/8) + 3/4 + 5/8= 9/8 + 3/4 + 5/8= (9+6+5)/8 = 20/8 = 5/2ozAs a result, the amount of specific hair dye produced by given ingredients = 5/2qz
To calculate the amount of each ingredient needed to make 1 oz of specific hair dye, multiply the reciprocal of 5/2 by each ingredient.The amount of red tone required to make 1 oz of a specific dye:
= 3/8 × 2/5 = 3/20 oz
Gray tone = 3/1 × 2/5 = 3/10 Oz Brown tone = 5/8 × 2/5 = 1/4 Oz=Now, multiply each by 20.
The amount of red tone required to make 20 oz of a specific dye:
3/20 × 20 = 3 oz
Gray tone = 3/10 × 20 = 6oz Brown tone = 1/4 × 20 = 5ozTo find each dye needed to make 100 ounces of dye, multiply the above amounts by 5.
(Since, 100 = 20 × 5)The amount of red tone required to make 20 oz of specific dye: 15oz
Gray tone is similar: 30 ozBrown tone is: 25 ozTherefore, the answers to both the questions are as follows:
We need 3 ounces of red tone, 6 ounces of gray tone, and 5 ounces of a brown tone to make 20 ounces of dye.We need 15 ounces of red tone, 30 ounces of gray tone, and 25 ounces of a brown tone to make 100 ounces of dye.Know more about ratios here:

c) The end behavior of the function is described as follows: As x -> -∞, y -> -2 and as x -> ∞, y -> -1.
What is a piecewise function?A piecewise function is a function that has different definitions, depending on the input.
For this problem, the definitions of the function are given as follows:
[tex]f(x) = 3^{x+1} - 2, x \leq 1[/tex].[tex]f(x) = \frac{-x^2 + x + 2}{x^2 - 3x + 2}, x > 1[/tex]The graph of the function is given at the end of the answer.
What is the range of the function?The range of the function is the set that contains all the output values of the function, and in a graph, this is the values of y.
Hence:
The range of the function is (-∞,7).
What are the asymptotes of the function?The asymptotes of the functions are the values of x for which the function is not defined. In this problem, the function is not defined for x = 2, hence the vertical asymptote is of x = 2.
The horizontal asymptotes are the values of the function when it goes to infinity, hence they are y = -2 and y = -1.
What is the end behavior of the function?The end behavior is given by the limits of the function as it goes to infinity, being closely related to the horizontal asympotes.
Hence:
As x -> -∞, y -> -2 and as x -> ∞, y -> -1.

LCM of 8, 16 and 24
Decompose to prime factors
8/2 = 4; 4/2 = 2. So 8 = 2 x 2 x 2

A diver is located at -157 feet relative to the surface of the water. If there is a shark swimming 38 feet above him,what is the position of the shark relative to the surface of the water
Answer: -119 feet relative to the surface of the water.
Step-by-step explanation:
Shark Depth ( x ) + Distance from Shark and Diver ( 38 ) = Divers position (-157)
x = -119
The diver is at -157 feet relative to the surface. The shark is swimming 38 feet above the diver, making its position -119 feet relative to the surface.
Given that,
Diver's depth: -157 feet (relative to the surface of the water)
Shark's position: 38 feet above the diver
The question asks for the position of the shark relative to the surface of the water.
The position of the shark can be determined by adding the distance above the diver to the depth of the diver.
So, the position of the shark would be:
-157 feet (diver's depth) + 38 feet (distance above the diver) = -119 feet relative to the surface of the water.
Hence,
The shark is located at -119 feet relative to the surface of the water.

What are the exterior angles of a triangle?When any side of a triangle is extended, the angle that is formed with this side and its adjacent side is called the exterior angle of a triangle. There are three exterior angles in a triangle. It should be noted that each exterior angle forms a linear pair with its corresponding interior angle.
Now, m∠5 + m∠6=180° (Adjacent angles are added up to 180°)
m∠2 + m∠3 = m∠6 (Exterior angle is equal to the sum of opposite interior angles)

Paulette is paid 2 1/2 % commission on all sales, and an extra 1 1/2 % on all sales over $6,500. Her sales last week totaled $17,400. What were her total earnings for the week?
The total earnings in the form of commission for Paulette is $ 598.5.
Commission till sales of $ 6,500 = 2 1/2 %
So amount of commission will be
A = 5 / 200 × 17400
A = 5 / 2 × 174
A = $ 435
Extra commission:
E = 3 / 200 × ( 17400-6500)
E = 3 / 200 × 10900
E = 3 / 2 × 109
E = $ 163.5
