Adrian has $1 worth of nickels and dime. He has twice as many nickels as dimes. Write a system of equations that could be used to determine the number of nickels and the number of dimes that Adrian has. Define the variables that you use to write the system.
Answer: We can use two variables, x and y, to represent the number of dimes and nickels Adrian has, respectively.
We know that Adrian has twice as many nickels as dimes, so we can write the equation:
y = 2x
We also know that the total value of the coins is $1, and since nickels and dimes have different values, we can write the equation:
0.05y + 0.1x = 1
So the system of equations is:
y = 2x
0.05y + 0.1x = 1
These equations can be solved simultaneously to find the number of nickels and dimes that Adrian has.

Determine whether y varies with x if so find the constant of variation and write the equation A. No b. Yes k= -2 and y= -2x
The equation is y = 2x and the constant of variation k = 2
Therefore, the correct answer is option d.
Here, we can clearly see that y varies directly with x, because as x increases, y increases with the same proportion and vice versa. The constant of variation, k, is the coefficient of proportionality between x and y. To find the constant of variation, we can divide the value of y by the value of x for any one of the given points.
For example, for the point (-2, -4) we have:
k = -4 / -2 = 2
So the equation relating x and y is: y = kx = 2x
Hence, the equation is y = 2x and the constant of variation k = 2
Therefore, the correct answer is option d.

What is reflex angle class 9?
A reflex angle is an angle which measures more than 180 degrees and less than 360 degrees.
There are different types of angles in geometry, such as obtuse, acute and right angles, which all are under 180 degrees.
Assume, z is an acute or obtuse angle, and r is the reflex angle, then:
z + r = 360
r = 360 - z
Therefore, we can find the related reflex angle(r), if we know the value of the acute or obtuse angle(z).
A reflex angle equals the summation of 180 degrees and any of the primary angles (acute, right and obtuse angles). Therefore,
Reflex angle = 180° + Acute angle
Reflex angle = 180° + Right angle

Three cards are chosen from a pack of 52 cards. what is the probability that they are not all the same color is 0.8824 or 88.24%
What is the definition of probability?The likelihood or chance that a specific event will occur is represented by a probability.
A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportion with a range of 0 to 1, or as percentages with a range of 0% to 100%.
Given that three cards are chosen from a pack of 52 cards.
There are 26 cards of each color (i.e. 26 cards are red color and 26 cards are of black color)
The probability of drawn first card of any one color is
P(1)= 26/52 = 1/2
The probability of drawn second card of same color is
P(2)= 25/51
The probability of drawn third card of same color is
P(3)= 24/50 = 12/25
The probability of having three cards are same color is
P = P(1)*P(2)*P(3)
P = 1/2 * 25/51 * 12/ 25
P = 6/51
So the probability that three cards are not all the same color is
P' = 1 - P
P' = 1 - 6/51
P' = (51-6)/51
P' = 45/51 = 15/17

Daria chooses a paint color from 5 shades of blue, 2 shades of yellow, and 2 shades of purple to paint her room. She can choose either carpet or wood flooring. If each choice is equally likely, how much greater is the probability of her choosing a shade of blue and carpet than the probability of choosing a shade of yellow and wood flooring?
The probability of choosing a shade of blue and carpet is 1/6 greater than that of choosing a shade of yellow and wood flooring.
The total number of possible paint colors Daria can choose is 5 shades of blue + 2 shades of yellow + 2 shades of purple = 9 shades
The total number of flooring options Daria can choose from is carpet or wood = 2 options
The probability of choosing a shade of blue is 5/9 and the probability of choosing carpet is 1/2. So, the probability of choosing a shade of blue and carpet is (5/9) * (1/2) = 5/18.
The probability of choosing a shade of yellow is 2/9 and the probability of choosing wood flooring is 1/2. So, the probability of choosing a shade of yellow and wood flooring is (2/9) * (1/2) = 2/18
The probability of choosing a shade of blue and carpet is 5/18, and the probability of choosing a shade of yellow and wood flooring is 2/18. So, the probability of choosing a shade of blue and carpet is (5/18) - (2/18) = 3/18 or 1/6 greater than the probability of choosing a shade of yellow and wood flooring.

x - y = 2
By adding both equations,
x + y + x - y = 10 + 2

2x + 3y + 3x - 3y = 10-15
5x = -5
x = -1
Example 3x + 4y = 5
3x - y = 2
To equalize the y term we multiply the second equation by 4

Worksheet fun balancing equations
The values of x are 16, 15, and 13 respectively after balancing equations 19 - 17 = x - 13, 18 - x = 19 - 16, and 17 - 12 = 18 - x.
what is equations ?It is thought that a number's simplest form is represented by its smallest equivalent fraction. finding the simplest form: what to do. For shared factors, look into the numerator and denominator. Examine a fractional integer to determine if it is a prime number. An equation is a statement that has two equal sides and an equal sign in the middle. In the general form of any equation, the degrees of all the variables are listed in descending order. The common representation of a linear equation is an x + b = 0. x + b y + c = 0 is the general form of a two-variable linear equation (or something similar). Identity or conditional equations are the two categories under which equations fall. An identity holds true regardless of how the variables are valued.

mary and max are playing a game with complex numbers. mary has a score of 3+2i. Wat must Max's score be so that the product of their score is one?
Since Mary and Max are playing a game with complex numbers, Max's score must be equal to 1/(3 + 2i), so that the product of their score is one.
What is a reciprocal function?A reciprocal function simply refers to a type of function which comprises a constant on its numerator and an algebraic expression or complex number in its denominator such as: f(x) = 2/3 + 7i.
In Mathematics, a reciprocal function is typically used when describing relationships that are inversely proportional to one other.
Let the variable n represent Max's score. Therefore, a mathematical expression which models the product of both Mary and Max's score is given by the following:
Product = 3 + 2i × n = 1
Making n the subject of formula, we have the following as Max's score;
n = 1/(3 + 2i)
Check:
3 + 2i × 1/(3 + 2i) = 1
(3 + 2i)/(3 + 2i) = 1
