The given system of equations 3x-2y=12 and 6x-4y=24 has no solution.
As per the question, we have to determine the solution to the following system of equations, 3x-2y=12 and 6x-4y=24
What is the equation?The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
Here,
Given a system of the equation,
3x-2y = 12
x = 12 + 2y / 3 - - - - -(1)
6x - 4y =24 - - - - -(2)
Put the value of equation 1 in the equation
6 (12 + 2y / 3) - 4y = 24
2 (12 + 2y) - 4y = 24
24 +4y - 4y = 24
24 = 24

Final answer:
The trinomial expression equivalent to (2x+5)(3x-2) is calculated using the FOIL method, resulting in 6x² + 11x - 10.
Explanation:
To write a trinomial expression equivalent to the product of two binomials, (2x+5)(3x-2), we perform the multiplication by using the distributive property (also known as the FOIL method).
Multiply the first terms: 2x × 3x = 6x²
Multiply the outside terms: 2x × (-2) = -4x
Multiply the inside terms: 5 × 3x = 15x
Multiply the last terms: 5 × (-2) = -10
Combine like terms:
6x² + (15x - 4x) - 10 = 6x² + 11x - 10
The trinomial expression equivalent to (2x+5)(3x-2) is 6x² + 11x - 10.

Maria wants to find the product of 5 3/20 multiplied by 3 4/25 using decimals instead of fractions how can she rewrite the problem using decimals
Answer:
[tex] 5.15\times 3.16=16.2740[/tex]
Step-by-step explanation:
Maria wants to find the product of [tex]5\frac{3}{20}[/tex] multiplied by[tex]3\frac{4}{25}[/tex]
First we change mixed fraction to fraction and then change into decimal.
#First fraction:
Change mixed to fraction[tex]5\frac{3}{20}\Rightarrow \dfrac{103}{20}[/tex]
Change fraction to decimal[tex]\dfrac{103}{20}\Rightarrow \dfrac{103\times 5}{20\times 5}=5.15[/tex]
#Secondfraction:
Change mixed to fraction[tex]3\frac{4}{25}\Rightarrow \dfrac{79}{25}[/tex]
Change fraction to decimal[tex]\dfrac{79}{25}\Rightarrow \dfrac{79\times 4}{25\times 4}=3.16[/tex]
Now we find the product of both decimal
[tex]\Rightarrow 5.15\times 3.16[/tex]
Using calculator product of 515 and 316 = 162740
Both number has decimal digits two
So, total number of decimal digits is 4
In multiply result write decimal before 4 digits from right.
Therefore,
[tex] 5.15\times 3.16=16.2740[/tex]

Find the value of x and the value of y.
A.x = 15, y = 10
B.x = 20, y = 50
C.x = 50, y = 10
D.x = 50, y = 20
Answer is C x=50 y=10
Answer:
C. [tex]x=50[/tex], [tex]y=10[/tex]
Step-by-step explanation:
We have been given an image of two intersecting lines. We are asked to find the value of x and y for our given diagram.
We know that when two line intersect each other, then vertical angles are congruent.
Using vertical angles theorem, we will get a system of equations as sown below:
[tex]3y=x-20...(1)[/tex]
[tex]5x-100=y+140...(2)[/tex]
From equation (1), we will get:
[tex]x=3y+20[/tex]
Upon substituting this value in equation (2), we will get:
[tex]5(3y+20)-100=y+140[/tex]
[tex]5*3y+5*20-100=y+140[/tex]
[tex]15y+100-100=y+140[/tex]
[tex]15y=y+140[/tex]
[tex]15y-y=y-y+140[/tex]
[tex]14y=140[/tex]
[tex]\frac{14y}{14}=\frac{140}{14}[/tex]
[tex]y=10[/tex]
Therefore, the value of y is 10.
To find the value of x, we will substitute [tex]y=10[/tex] in equation (1) as:
[tex]3*10=x-20[/tex]
[tex]30=x-20[/tex]
[tex]30+20=x-20+20[/tex]
[tex]50=x[/tex]
Therefore, the value of x is 50 and option C is the correct choice.
Answer:
Option C) x = 50, y = 10
Step-by-step explanation:
We are given a two pairs of vertically opposite angle in the image.
Vertically opposite angle is formed when two lines intersect anf they are always equal.
Thus, we can write:
[tex]3y = x -20\\\Rightarrow x - 3y = 20\\5x-100 = y +140\\\Rightarrow 5x - y =240[/tex]
Solving the two equations in two variable, we get:
[tex]x - 3y = 20\\5x - y =240\\\text{Multiplying first equation by 5}\\5x - 15y = 100\\\text{Subtracting the equations}\\5x - 15y-(5x-y) = 100-240\\-14y = -140\\y = 10\\ x - 3(10) = 20\\x = 20 + 30\\x =50[/tex]
The value of x is 50 and y is 10.

In a number of identical boxes of chocolates there are 90 dark ginger, 198 white and 126 hazelnut. What is the largest possible number of boxes of chocolates?
The problem involves finding the Greatest Common Divisor (GCD) of the three numbers. The GCD of 90, 198, and 126 is 18. Hence, the largest possible number of identical boxes of chocolates is 18.
Explanation:The problem involves finding the Greatest Common Divisor (GCD) of the three quantities to find the largest possible number of identical boxes of chocolates. The GCD is the largest number that divides all three quantities evenly. So, let's first calculate the GCD of the given quantities: 90 dark ginger, 198 white, and 126 hazelnut chocolates.
We use the Euclidean Algorithm to find the GCD. Start with the two largest numbers, 198 and 126. The remainder of 198 divided by 126 is 72. Then, divide the initial divisor 126 by this remainder 72 to get another remainder 54. Continue this process with 72 and 54 to get a remainder 18. Now, the number 18 divides 54 exactly with 0 remainder, so 18 is the GCD of 198 and 126. When we test 18 with the third number, 90, it also divides evenly, hence the GCD of all three numbers is 18.
This means that the largest possible number of identical boxes of chocolates is 18.

Final answer:
The distance between point A (5, 3) and point B (-3, 9) is calculated using the distance formula, resulting in a distance of 10 meters.
Explanation:
The question is asking for the distance between two points in a coordinate system. To find the distance between point A (5, 3) and point B (-3, 9), we can use the distance formula which is derived from Pythagorean theorem. The distance d between two points (x1, y1) and (x2, y2) is given by:
d = √((x2 - x1)² + (y2 - y1)²)
For point A and point B, we substitute the coordinates into the formula:
d = √((-3 - 5)² + (9 - 3)²)
= √(64 + 36)
= √100
= 10 meters
Therefore, the distance from A to B is 10 meters.

5.5-x=-4.5-x. how do you solve this?
The equation 5.5 - x = -4.5 - x has no solution. After cancelling out the variable x, we are left with 5.5 = -4.5, which is a contradiction.
Explanation:To solve the equation 5.5 - x = -4.5 - x, we first notice that the variable x is present on both sides of the equation. We can simply subtract or add x to both sides to cancel it out. This will give us an equation without variables:
5.5 - x + x = -4.5 - x + x
5.5 = -4.5
This equation suggests that 5.5 is equal to -4.5, which is not true. Therefore, we can conclude that there is no solution to the equation since the two sides of the equation do not balance.
Moreover, this type of equation is an example of a contradiction, meaning that it presents a statement that is inherently false regardless of the value of x. As there is no value of x that can make the equation true, we say that the equation has no solution.
Final answer:
The equation 5.5 - x = -4.5 - x simplifies to 5.5 = -4.5 when the x terms are cancelled out. Since 5.5 does not equal -4.5, the equation has no solutions.
Explanation:
To solve the equation 5.5 - x = -4.5 - x, we can first try to simplify it by adding or subtracting the same value from both sides. This method is based on the principle that whatever you do to one side of the equation, you must do to the other to maintain balance.
In this case, if we add x to both sides of the equation, the x terms will cancel out on both sides, which leaves us with 5.5 = -4.5. Here, we notice that both sides of the equation represent constant values and no longer contain the variable x.
Therefore, since 5.5 and -4.5 are not equal, we can conclude that there is no value of x that can satisfy this equation. This equation is a contradiction, which means there are no solutions.
