Drag each label to the correct location on the image. Identify which equations have one solution, infinitely many solutions, or no solution.
Answer:
"1/2y+3.2y=20" One solution
"15/2+2z-1/4=4z+29/4-2z" Infinitely many solutions
"3z+2.5=3.2+3z" No solution
"1.1+3.4x+2=3.1+3/4x" infinitely many solutions
"4.5r=3.2+4.5r" No solution
"2x+4=3x+1/2" one solution
To determine the number of solutions for each equation in the given image, we need to analyze each equation separately. Let's go through each equation and identify whether it has one solution, infinitely many solutions, or no solution.
Equation 1: 3x - 2y = 6 Equation 2: 6x - 4y = 12 Equation 3: 2x - y = 3
To find the solutions, we can use the method of substitution or elimination.
First, let's consider Equation 1: 3x - 2y = 6
If we rearrange this equation to solve for y, we get: y = (3x - 6) / 2
Now, let's examine Equation 2: 6x - 4y = 12
If we rearrange this equation to solve for y, we get: y = (6x - 12) / 4 y = (3x - 6) / 2
Comparing the two equations for y, we can see that they are the same. This means that Equation 1 and Equation 2 represent the same line.
In other words, they have infinitely many solutions.
Any point on the line formed by these equations satisfies both equations simultaneously.
Moving on to Equation 3: 2x - y = 3 If we rearrange this equation to solve for y, we get: y = 2x - 3
This equation represents a line with a specific slope and y-intercept. Since it is different from the line represented by Equation 1 and Equation 2, we can conclude that Equation 3 has one solution.
This means that there is a unique point of intersection between Equation 3 and the other two equations.
In summary: - Equation 1 and Equation 2 have infinitely many solutions since they represent the same line.
- Equation 3 has one solution since it intersects the other two equations at a unique point.

Step-by-step explanation:
Answer:
2x-7=4
Step-by-step explanation:
seven less is a number minus 7 so __ - 7
a product of a number and 2 is multiplication so 2 * x or 2x therefore 2x-7

How to solve 3x+12=2x
Answer: x=-12
Step-by-step explanation:
subtract 12 from both sides
3x=2x-12
subtract 2x from both sides
x=-12
Subtract 12 from both sides of the equation:
3x + 12 = 2x
3x + 12 - 12 = 2x - 12
Simplify:
3x = 2x - 12
Subtract 2x from both sides of the equation:
3x = 2x - 12
3x-2x = 2x - 12-2x
Simplify:
combine like terms --> multiply by 1 --> combine like terms
x = -12 <-- ANSWER
Steven noticed that there were 72 lights on and 78 lights turned off. Enter the percent of the lights turned on.
The lights which were on was 48%.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
Given that there were 72 lights on, and 78 lights turned off.
We need to find the percent of the lights turned on.
So, percentage of something =
= number of thing / total number of the thing x 100%
Here, the number of thing = light on = 72
Total = 72 + 78 = 150
So, the percent of light on = 72 / 150 x 100% = 0.48 x 100%
= 48%
Hence the lights which were on was 48%.

Answer:
4.9 = 490%
15.27% = .1527
Step-by-step explanation:
1. To convert a decimal into a percentage, you multiply the decimal by 100.
For example, if we convert the number 1.01 into a percentage by multiplying it by 100, we get 101%. When converting from percentage to decimal, you divide by 100.2. (Solving)
4.9:
[tex]4.9 * 100[/tex] [tex]49 * 10[/tex] [tex]490[/tex] 490%15.27%:
[tex]15.27/100[/tex] [tex]1.527/10[/tex] [tex].1527[/tex]Therefore, the answers are 490% and .1527.
Answer: 490% and .1527

Solve for the value of ee.
Answer:
Step-by-step explanation:
Two angles are supplementary, that means their sum is equal to 180 degrees
3e - 4 + e + 8 = 180 add like terms
4e + 4 = 180 subtract 4 from both sides
4e = 176 divide both sides by 4
e = 44

Benjamín le dijo a Gustavo el doble del dinero que tengo más la mitad de esa cantidad es 200 pesos ¿con cuánto dinero cuenta Benjamín?
Considerando la definición de una ecuación, Benjamín cuenta con una cantidad de dinero de 66.67 pesos.
Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos.
Los miembros de una ecuación son cada una de las expresiones que aparecen a ambos lados del signo igual.
En este caso, "el doble del dinero que tengo más la mitad de esa cantidad es 200 pesos" puede ser expresado mediante una ecuación, donde consideras que "x" es la incógnita, que representa la cantidad de dinero que tiene Benjamín.
Teniendo en cuenta que la mitad de un número se calcula dividiendo el número por 2, mientras que el doble de un número se calcula multiplicando el número por 2, entonces:
El doble del dinero que Benjamín tiene es: 2xLa mitad de esa cantidad es: (2x)÷2= xEntonces, la ecuación queda expresada como:
2x + x= 200
Resolviendo:
3x= 200
x=200÷3
x= 66.67
Finalmente, Benjamín cuenta con una cantidad de dinero de 66.67 pesos.

Answer:
DE is 4 units long.
Step-by-step explanation:
These are the 30-60-90 triangle side relationships:
Short leg × 2 = hypotenuseShort leg × √3 = long legLong leg ÷ √3 = short legHypotenuse ÷ 2 = short legWe are given the long leg and need to find the short leg. As seen above, the relation ship between those sides is:
[tex]S*\sqrt{3}=L[/tex]
or:
[tex]L \div \sqrt3 =S[/tex]
Given the long leg, divide it by √3 to find the short leg.
[tex]4\sqrt3 \div \sqrt3 = 4[/tex]
The short leg is 4 units long.
3x + y + z = 6
3x - 2y + 2z = 14
3x + 3y - 3z = -6
Let's solve for x.
3x+y+z=6
Step 1: Add -y to both sides.
3x+y+z+−y=6+−y
3x+z=−y+6
Step 2: Add -z to both sides.
3x+z+−z=−y+6+−z
3x=−y−z+6
Step 3: Divide both sides by 3.
3x3
=−y−z+6/3
x=−1/3y+−1/3z+2

We require to find the 3rd angle in the triangle, that is
third angle = 180° - (75 + 50)° = 180° - 125° = 55°
Using the Sine rule in the triangle
[tex]\frac{x}{sin75}[/tex] = [tex]\frac{13}{sin55}[/tex] ( cross- multiply )
x × sin55° = 13 × sin75° ( divide both sides by sin55° )
x = [tex]\frac{13sin75}{sin55}[/tex]
