The value of x in the given equation is 24.
Given equation:
(2/3)x + 4 = (5/6)x
We have to find the value of x by eliminating the fraction.
Fraction
Fraction is termed as a portion or section of any quantity. It is denoted by using ‘/’ symbol, such as a/b. For example, in 2/4 is a fraction where the upper part denotes the numerator and the lower part is the denominator.
LCM (3,6) = 6
Multiplying the whole equation by 6, we get:-
(2/3)x*6 + 4*6 = (5/6)x*6
4x + 24 = 5x
5x - 4x = 24
x = 24
Hence, the value of x is 24.

She plans on washing cars for $25 per car.
Ereed wash c cars to have enough to purchase the bicycle.
Select the 3 orrect equations below that can be used to represent when she will be able to purchase the bicycle she wants
The correct equations which can be used to represent when she will be able to purchase the bicycle she wants are:
250 = 125+25c125 = 25cc = 5Given, Eva wants to buy a bicycle.
The cost of bicycle is = $250
Saving's of Eva = $125
Eva plans on washing cars for $25 per car.
Eva wash 'c' cars to have enough to purchase the bicycle.
cost of bicycle = saving's of Eva + Eva washing 'c' cars for $25 per car.
⇒ 250 = 125 + 25c
arrange the like terms on one side.
⇒ 250 - 125 = 25c
⇒ 125 = 25c
⇒ 25c = 125
⇒ c = 125/25
⇒ c = 5
hence Eva washes 5 cars to earn $125 which gets added to the savings and becomes the cost of the bicycle she wants to purchase.
⇒ cost of bicycle = 125+25(5)
⇒ cost of bicycle = 125+125
⇒ cost of bicycle = $250
Hence we got the required answers.

A restaurant has a total of 20 tables -> Round tables that seat 2 people and rectangular tables that seat 4 people. All 70 seats in the restaurant are occupied.
write system of equation to represent this scenario.
The system of equations to represent this scenario is x + y = 20 and 2x + 4y = 70 .
In the question ,
it is given that
the total number of tables in the restaurant = 20 tables
let the number of round tables be "x"
let the number of rectangular tables be "y" .
number of person that can seat on a round table = 2
So , the number of person that can seat on "x" round tables = 2x person
number of person that can can seat on rectangular table = 4
So , the number of person that can seat on "y" rectangular tables = 4y person
since total number of table is 20
So , the equation is x + y = 20
and total number of person that can seat are 70 seats .
So , the equation is 2x + 4y = 70
Therefore , The system of equations to represent this scenario is x + y = 20 and 2x + 4y = 70 .

Answer: A z=9
Step-by-step explanation:
Answer:
z = 12
Step-by-step explanation:
To understand the equation, you must first know that m∠a = 108°. It equals that because a regular five-sided polygon has an interior angle of 108° each.
Next, you would want to group all constants to the right side of the equation. By doing so, you want to subtract 72 from both sides.
(3z + 72) - 72 = 108 - 72
3z = 36
Lastly, you want to isolate the z by dividing 36 by 3.
z = 36 ÷ 3
z = 12

Marcus runs triathlons (races that involve running, biking, and swimming). To prepare for these triathlons, he follows a strategy of running twice as far as he swims and biking fours times as far as he runs. If he swims for 3 miles this week, what is the total distanch of his swimming, running and biking this week?
1) Gathering the data
Strategy:
Running : 2x As he swims
Biking: 4x Runs
Runs = 3 miles
Then
2) Runs = 3 miles Swims = 6 miles Biking = 12 miles
The Total distance will be the sum of those activities:

Tell whether the value is a solution of the inequality -1 > -x/2; x=3
Answer:
Yes, X = 3 is a solution
Step-by-step explanation:
We start by inputing 3 into the equation giving us -1 > -(3)/2
This means we have -1 > -3/2
Now we have to determine if this statement is true.
-1 Is greater than -3/2, because -3/2 is -1.5 as a decimal which is less than -1.
Meaning 3 is a solution
The vertices of △ABC are A(2, −3), B(−3, −5), and C(4, 1). If (x,y)--> (x-4, y-1), give the vertices of △A′B′C′.
Answer:
A' = (-2, -4)
B' = (-7, -6)
C' = (0, 0)
Step-by-step explanation:
Vertices of triangle ABC:
A = (2, -3)B = (-3, -5)C = (4, 1)Given mapping rule:
(x, y) → (x - 4, y - 1)
This notation tells you that the x-coordinate is translated 4 units to the left, and the y-coordinate is translated 1 unit down.
Substitute the coordinates of each point into the mapping rule to find the vertices of triangle A'B'C':
⇒ A' = (2 - 4, -3 - 1) = (-2, -4)
⇒ B' = (-3 - 4, -5 - 1) = (-7, -6)
⇒ C' = (4 - 4, 1 - 1) = (0, 0)
What is the midpoint of line segment (-6,-10) ,(-2,-8)
The mid-point of two coordinates is the average of the x and y coordinates thus the midpoint of the line segment with endpoints (-6,-10),(-2,-8) is (-4,-9).
What is a line segment?A line section that can connect two places is referred to as a segment.
A line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The midpoint associated with two points (x₁, y₁) and (x₂, y₂) is given by
x = (x₁ + x₂)/2 , y = (y₁ + y₂)/2
x = (-6 - 2)/2 = -4 , y = (-10 - 8)/2 = -9
So, the coordinate will be (-4,-9).
Hence "The mid-point of two coordinates is the average of the x and y coordinates thus the midpoint of the line segment with endpoints (-6,-10),(-2,-8) is (-4,-9)".

Factor completely. 4x^2-x-5
The factors of the given equation 4x^2-x-5 are 5/4 and -1.
What is referred as the factors of the polynomial?Factoring polynomials is the inverse procedure of multiplying polynomial factors. Factors of polynomials are zeros of polynomials that take the form of some other linear polynomial. If we divide a given polynomial by any of its factors after factorisation, the remainder would be zero.Factors are integers which are multiplied together to create the original number. The factors in the particular instance of polynomials are the polynomials that are multiplied to generate the original polynomial.For the given question, the expression is given as;
= 4x^2-x-5
as, 4×5 = 20, break the number such that on subtraction we will get -1.
= 4x^2 - 5x + 4x -5
Taking x common from first two digit.
= x(4x - 5) + (4x - 5)
Taking common again.
= (4x - 5)(x + 1)
Put the equation equal zero to find the factor.
4x - 5 = 0
x = 5/4
and, x + 1 = 0
x = -1
Thus, the factors are found as 5/4 and -1.

1. Given the function g(x)=(x-4)² + 3
I’ve been asked to graph the function but they gave me no reference points to be able to find my corresponding points how do I find them with just the function?
There is no need of reference points to plot the graph of this function and we can select our reference range by ourselves as discussed above. The graph is attached in the end.
What is a function?A function is a relation between a independent variable and a dependent variable such that the value of dependent variable depends upon the independent one. For example -
f(x) = 2x + 5
g(x) = 4x + 9
Given is function g(x) = (x - 4)² + 3
There is no need of any reference points to graph this function. You can take the reference points in a specific range. For example, you can plot the graph for the values of [x] from x = -5 to x = 5. It can be noticed that we have taken 5 - 5 points on both sides of the [x] axis. Make sure that you ensure this symmetry. Range could be any, for example from x = - 7 to 7, x = - 10 to 10 etc. The given function is -
g(x) = (x - 4)² + 3
We will plot the graph for x = -3 to x = 3
g(-3) = 52
g(-2) = 39
g(-1) = 28
g(0) = 19
g(1) = 12
g(2) = 7
g(3) = 4
Now, we will plot these coordinates on the graph. The plotted graph is attached with the answer.
Therefore, we can conclude that, there is no need of reference points to plot the graph of this function and we can select our reference range by ourselves as discussed above.
