Using percentage and equations, Greg has 734 songs, Raj has 426 songs and Mark has 720 songs
What is PercentagePercentage is a way of expressing a number as a fraction of 100. It is often denoted using the percent symbol, "%". For example, 45% (read as "forty-five percent") is equal to 45/100, or 0.45. Percentages have no dimension, which it's why they are dimensionless number. for example 60% of a number, then it means 60 per cent of its whole.
In this problem, we can write an equations and solve to determine the number of songs Greg has on his computer.
Let;
x = number of songs Greg hasy = Number of songs Raj hasSince Mark has 720 songs in his computer;
x = 14 + 720
x = 734
Greg has 734 songs
We can calculate the number of songs Raj has by;
y = 60%(720) - 6
y = [(0.6) * 720] - 6
y = 426

What is the equation of the line graphed below?
Answer: -2/3x is the slope and the beginning amount is 5 so the equation would be -2/3x+5.
Step-by-step explanation:
Once you find the slope using the formula rise/run you will get 2/3 but since the slope is going downwards it would be -2/3 which gives you the mx. Now to find the beginning amount look where the line intersects the graph which will give you the equation.
write a linear equation that passes through the points (2,-7) and (4,-9) and has a slope "-5"
Step-by-step explanation:
a line passing through 2 points get a slope just by these 2 points.
all we can do is to verify that the given slope is the same as the slope defined by the 2 points.
the slope is the ratio
y coordinate change / x coordinate change
when going from one point on the line to another.
for our 2 points that gives us
x changes by + 2 (from 2 to 4).
y changes by -2 (from -7 to -9).
the slope is therefore
-2/+2 = -1
the question asks for a slope of -5.
that is a contradiction. there is no line possible to pass through both points and have a slope of -5.

A tore i having a ale on almond and jelly bean. For 5 pound of almond and 2 pound of jelly bean, the total cot i $12. For 3 pound of almond and 8 pound of jelly bean, the total cot i $31. Find the cot for each pound of almond and each pound of jelly bean
b = $3.5 the cost of each pound of jelly beans.
a = $1, the cost of each pound of almonds
What is the elimination method?
The elimination approach involves taking one variable out of the system of linear equations by utilizing addition or subtraction together with multiplication or division of the variable coefficients.
Here,
We let a be the almond and b be the jelly bean.
5a + 2b = $12....(1)
3a + 8b = $31....(2)
...Solving by elimination method.
5a = 12 - 2b
a = (12 - 2b)/5
Now, we put the value of a in equation(2)
3a + 8b = $31
3(12 - 2b)/5 + 8b = 31
(36 - 6b)/5 + 8b = 31
36 - 6b + 40b = 155
34b = 155 - 36
34b = 119
b = $3.5 the cost of each pound of jelly beans.
a = $1, the cost of each pound of almonds.

cross-multiply:
5x = 80
x = 16
Kate can mow lawns at a constant rate of 16 lawns in 20 hour.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Kate can mow lawns at a constant rate of 4/5 lawns per hour.
Now,
Since, Kate can mow lawns at a constant rate of 4/5 lawns per hour.
Hence, In 20 hours;
Kate can mow lawns = 20 × 4/5

How do you solve 3 composite functions?
To solve 3 composite functions, you would need to break each function down into its individual components. Then, you would need to combine each component one at a time, starting with the outermost function and working your way inwards.
1. Break each function down into its individual components. This may involve splitting them into simpler functions such as polynomials, exponentials, trigonometric functions, and so on.
2. Start with the outermost function and combine each component one at a time. Make sure to apply the order of operations to each step in order to get the correct result.
3. Evaluate the combined function. This means solving for the output of the function, which may involve plugging in values for certain variables.
4. Repeat the same process for the other two functions.
5. When you have evaluated all three functions, you can combine the results of each to get the answer to the composite functions.

Whats 3x+1? for in high school its really hard to solve none of my friend cant do it
As per the zeros of the function, the value of the function 3x + 1 is x = -1/3.
Zeros of the function in math is defined as the values of the variable of the function such that the function equals 0.
Here we have given the function 3x + 1.
Now, we have to equate the function with zero, in order to solve it, then we get,
=> 3x + 1 = 0
Now, we have to subtract 1 on both sider to individualize the x value then we get the rewritten expression as,
=> 3x = -1
Now, we have to divide each side by 3, then we get the value of x as,
=> x = -1/3

What is an equation?The meaning of such an equations in algebra is just a mathematical expression stating the equality between two mathematical terms. For instance, 6x + 5 = 11 is an equation where 6x + 5 and 11 are two expressions separated by the 'equal' sign.
Identity equations and conditional equations are the two types of equations. For just any value of both the variables, an equality remains true. Only such variables have values that make a condition expression true. Two expressions joined by an equals sign ("=") form an equation.

51.5 g
54.1 g
55.8 g
58.5 g
Answer:
51.5g or A
I took a test with this question and got it right
Using the normal distribution, it is found that approximately 80% of the eggs on the farm have a mass greater than 51.5 g.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 55, \sigma = 4.2[/tex].
Approximately 80% of the eggs on the farm have a mass greater than the 20th percentile, which is X when Z = -0.84, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.84 = \frac{X - 55}{4.2}[/tex]
X - 55 = -0.84 x 4.2
X = 51.5 g.

Find the value of each variable in the following parallelograms.
Answer:
x = 15
y = 7.5
Step-by-step explanation:
✔️Diagonals of a parallelogram bisect each other at 90°.
Therefore,
2x° + 60° + 90° = 180° (sum of triangle)
Solve for x
2x + 150 = 180
2x = 180 - 150
2x = 30
2x/2 = 30/2
x = 15
✔️2x = 4y (alternate angles/corresponding angles)
Plug in the value of x
2(15) = 4y
30 = 4y
30/4 = y
7.5 = y
y = 7.5

Use the graph or the formula to write the equation of the line in a slope intercept form
The equation of line passing through (-9,-10) and(7,-3) will be y = (7/16)x - 1
What is slope?Slope is a measure of the steepness of a line, and it is also known as the "gradient." It is a ratio of the vertical change (rise) to the horizontal change (run) between two points on a line. It is often represented by the letter "m" in the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).
What is the formula to find the equation of line given the two points?The formula to find the equation of a line given two points is:
y - y1 = m(x - x1)
where (x1,y1) and (x2,y2) are the coordinates of the two points on the line, and m is the slope of the line, which can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
m = (y2 - y1) / (x2 - x1)
where (x1,y1) and (x2,y2) are the coordinates of the two points.
so the slope m = (-3 - (-10)) / (7 - (-9)) = 7/16
We can use point slope form to get the equation of the line passing through the two points:
y - y1 = m(x - x1)
so the equation of the line is y - (-10) = (7/16)(x + 9)
=> y = (7/16)x + (-10) + (9 * 7/16)
=> y = (7/16)x - 1
