What is simultaneous equations?Two or more algebraic equations that share variables, such as x and y, are said to be simultaneous equations. Since the equations are solved simultaneously, they are known as simultaneous equations. These equations alone could have an endless number of solutions.A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system. In order to create a single equation that contains the other unknown, one of the unknowns must be removed or eliminated. It is best to use examples to explain the process. Example Address the parallel equations. 3x + 2y = 36 (1) 5x + 4y = 64 (2) . y = 6 So, x = 8 and y = 6 is the complete solution.Consider the equation 3x+y=2

Judy and Cassie each opened a savings account on the same day. Judy started by putting $300 in her account, and she will deposit an additional $12 each week. Cassie made an initial deposit of $100, and she will add $20 more each week. Eventually, Judy and Cassie will each have the same amount saved. How many weeks will that take?
Write a system of equations, graph them, and type the solution.
Answer: 25 weeks
Step-by-step explanation:
Let W represent the number of weeks
Judy equation is
12W + 300
Cassie equation is
20W + 100
Now let's solve it! Our system of equation is
12W + 300 = 20W + 100
Subtract 300 from both sides
12W = 20W -200
Subtract 20W from both sides
-8W = -200
W = 25 weeks
So, it takes 25 weeks for Judy and Cassie to have the same amount saved.
Answer:
let judy = 300 + 12W
cassie = 100 + 20W
300 + 12W = 100 + 20W
300 - 100 = 20W - 12W
200 = 8W
W = 25
CHECKING:
300 + 12(25) = 100 + 20(25)
300 + 300 = 100 + 500
600 = 600
Therefore, it will take 25 days for Judy and Cassie so that they have the same amount saved.

a cone with a radius of 4.96 and a volume of 102
The volume of a cone is given by the formula:
V = (1/3) * π * r² * h
Where V is the volume, r is the radius, and h is the height.
In this case, we know the radius (4.96) and the volume (102), so we can use the formula to solve for the height.
Substituting the known values into the formula, we get:
102 = (1/3) * π * (4.96)² * h
Dividing both sides by (1/3) * π * (4.96)², we get:
h = 102 / [(1/3) * π * (4.96)²]
Substituting in the value for π, we get:
h = 102 / [(1/3) * 3.14 * (4.96)²]
Which simplifies to:
h = 102 / [(1/3) * 3.14 * 24.1952]
Which simplifies to:
h = 102 / (0.7853 * 24.1952)
Which simplifies to:
h = 102 / 19.1268
Which is approximately 5.33.
Therefore, the estimated height of the cone is approximately 5.33.

The dot plots show rainfall totals for several spring storms in highland areas and lowland areas.
The dot plots show that the lowland areas experienced significantly more rainfall than the highland area during spring storms, with a larger range and maximum rainfall.
The dot plots show the rainfall totals for several spring storms in both highland and lowland areas. The dots representing the lowland areas are more spread out and have a larger range compared to the dots representing the highland areas. This indicates that the lowland areas experienced more rainfall than the highland areas during these storms. Additionally, the maximum rainfall for the lowland areas is greater than the maximum rainfall for the highland areas, further emphasizing the difference in rainfall between the two areas. This could be due to a number of factors, such as the higher elevation of the highland areas resulting in less moisture being able to accumulate, or the lower temperature of the highland areas resulting in less evaporation and thus less rainfall. Additionally, the lower elevation of the lowland areas could result in more moisture being able to accumulate, and the higher temperature of the lowland areas could result in more evaporation, leading to increased rainfall. Regardless of the cause, the data from the dot plots clearly show that the lowland areas experienced more rainfall than the highland areas during these spring storms.

b) mean=95, standard deviation=7.2
c) mean=95, standard deviation=12
d) mean=95, standard deviation=72.2
e) mean=77, standard deviation=12
Answer:
(b) mean=95, standard deviation=7.2.
Step-by-step explanation:
To find the new mean and standard deviation, we first need to apply the transformation to the original mean and standard deviation.
The new mean is given by: x*=65+0.6x
Substituting in the original mean of 50, we get: x*=65+0.6(50) = 95
The new standard deviation is given by: s*=0.6s
Substituting in the original standard deviation of 12, we get: s*=0.6(12) = 7.2
Therefore, the new mean and standard deviation are (b) mean=95, standard deviation=7.2.

How to determine the zero of the graph?From the question, we have the following parameters that can be used in our computation:
Major points on the graph are (minus 4, 0), (0, 1), (2, 2), (4, 5.5), and (6, 6).
Express the points, properly
So, we have the following representation
Major points on the graph are (-4, 0), (0, 1), (2, 2), (4, 5.5), and (6, 6).
Write out the points
(-4, 0), (0, 1), (2, 2), (4, 5.5), and (6, 6).
The zeros of the graph are the point where y = 0
In this case, the points are
(-4, 0)
So, we have
x = -4
Hence, the zero is x = -4

how do you solve this ?
Step-by-step explanation:
first of all, remember for life :
the sum of all angles in a triangle is always 180°.
so, in this right-angled triangle we have therefore
180 = b + 90 + 71
b = 180 - 90 - 71 = 19°
and then regarding a and b :
the sum of all angles around a single point on one side of a line is also always 180°.
why ? because the line can be seen as the extended diameter of a circle, with that point being the center of the circle. and one side of the line is representing half of that circle. and a half-circle is 180°.
so,
a + b = 180
a + 19 = 180
a = 180 - 19 = 161°
FYI, the reason for the first principle (all angles in a triangle are together 180°) is also based on a half-circle concept : any right-angled triangle can be seen as inscribed into a half-circle, with the Hypotenuse (the baseline opposite of the 90° angle) being the diameter of the circle, and the center of the circle being the midpoint of the Hypotenuse.
What are the roots of the quadratic equation x² 5x 6 0?
The two solutions to the equation x² + 5x + 6 = 0 are x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.
To find the roots of a quadratic equation, we need to set the equation equal to 0 and then solve for x. In this case, we have the equation x² + 5x + 6 = 0. we can use the quadratic formula. The quadratic formula states that the two solutions for x are given by x = (-b ± √(b² - 4ac))/2a. For our equation, this gives us x = (-5 ± √(5² - 4(1)(6)))/2(1). Once we simplify this, we get x = (-5 ± √(-19))/2. Since the square root of a negative number is not real, we can discard this solution. This leaves us with x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.
x = (-5 ± √(5² - 4(1)(6)))/2(1)
= (-5 ± √(-19))/2
= (-5 ± i√19)/2

A cuboid has a lateral surface of 260 cm and a height of 10 cm. The dimensions of the base are: one is 3 cm smaller than the other. Instruction: First, we find the perimeter of the base of the cuboid as a ratio of the side surface to the height. (260cm2: 10cm=26 cm.) Then we write the equation x+x-3+x+x-3=26cm, where with x we marked one of the sides, we find the sides
Answer:
A cuboid is a 3-dimensional shape with six rectangular faces, four of which are the sides or lateral faces, and the other two are the base and the top. To solve the problem, we can first find the perimeter of the base of the cuboid by dividing the lateral surface area by the height. In this case, the perimeter of the base is 26 cm.
To find the dimensions of the base, we can set up an equation using the given information. Let x be one of the sides of the base, and let y be the other side. Since one of the sides is 3 cm smaller than the other, we can write the equation as:
x + x - 3 + x + x - 3 = 26 cm
We can simplify the equation by combining like terms:
4x - 6 = 26 cm
Next, we can solve the equation by adding 6 to both sides and then dividing by 4:
4x = 32 cm
x = 8 cm
Therefore, the dimensions of the base of the cuboid are 8 cm x 11 cm (since one side is 3 cm smaller than the other). The perimeter of the base is 26 cm, and the height of the cuboid is 10 cm.
