Answer:
Sierra=2songs
Matt=7songs
Yun SIl=14songs
step-by-step explanation:
Step 1
Let,The number of songs YunSil added = x
Number of songs Matt added = y
And number of songs Sierra added = z
Such that Matt has 5more than Sierra =y = 5 +z
Yun SIl has 2 times more thann Matt, x = 2y
x =2(5+z)=10 +2z
Step 2
The expression used to determine number of songs on each player given that the total of songs added on the three players =15 +z^3
Such that
YunSil+Matt+Sierra==15 +z^3
10+2z+ 5+z +z = 15 +z^3
4z +15 = 15 +z^3
4z=15-15+z^3
4z=+z^3
4=z^3/z
4=z^2
Z=√4 =2
Therefore Sierra has z=2songs
Matt has 5+z=5+2=7songs
YunSil has 2(5+z)= 2x7=14songs
The song that are on each person player are as follows;
matt song = 7
Yung Sil song = 14
Sierra song = 2
Let
a = Matt song added
b = Yun Sil song
c = Sierra song =
Therefore,
b = 2a
a = c + 5
(c + 5 + 2a + c) - c³ = 15
(2c + 2(c + 5) + 5) - c³ = 15
2c + 2c + 10 + 5 - c³ = 15
4c + 15 - c³ = 15
4c - c³ = 0
c³ = 4c
c² = 4
c = √4
c = 2
a = 2 + 5 = 7
b = 2(7) = 14

Britt has decided that she wants to earn $4,000 over the next 10 months to set aside for a down payment on a car. Britt currently works some afternoons and evenings babysitting. She makes $8 per hour. At this pay rate, how many hours will Britt need to work each month to accomplish her goal?
This question is dealing with rates. Rates are just to show a measure of what we are to use, give or pay e.t.c per time as the case may be.
Britt needs to work 50 hours each month to accomplish her goal.
She wants to make $4,000 and she makes $8 per hour.
This means, amount of hours she need to make $4,000 is;
4000/8 = 500 hours
Since she wants this money over 10 months, it means every month she needs to work; 500/10 = 50 hours per month.
In conclusion, britt needs to work 50 hours each month to accomplish her goal.

Answer:
The slope is 2
Step-by-step explanation:
To solve for slope, it's: y2-y1/ x2-x1.
The points can be (1,0) and (2,2) since they intersect with the slope.
You plug the points into the equation which is 2-0/ 2-1.
This will give you 2/1 or just 2.
Or you can just do rise over run. The slope is going up by 2 and across by 1.
Categorize the graph as linear increasing, linear decreasing, exponential
growth, or exponential decay.
A.Exponential decay
B. Linear decreasing
C. Linear increasing
D. Exponential growth
Answer:
B
Step-by-step explanation:
Since the graph shows a straight line and not a curved graph, this is a linear equation.
And since the line is sloping downwards, it is decreasing.
Our final answer is linear decreasing.
The category of the function of the graph in the figure is a (b) Linear decreasing graph
How to determine the graph category?Any graph that is represented by a straight line is a linear graph
The above statement means that the graph is a linear graph because it is represented by a straight line.
The orientation of the line also means that:
As x increases, the value of y decreases
Hence, the category of the graph is a (b) Linear decreasing graph

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The height of the tree is equal to 98 feet.
What is Tangent (Tanθ)?
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
Using the tangent function of the trigonometry, we can write the ratio of the height to the base will be equal because the angle of sun rays is the same for both.
Height of Tree /Shadow of Tree = Height of the biologist / Shadow of the biologist
Height of the tree/ 28 = 7/2
Height of the tree = (28×7)/2
Height of the tree = 98 feet
Hence, the height of the tree is equal to 98 feet.

Answer:
The solution to the system of equations be:
x = 0.5, y = -0.5
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}2x+4y=1\\ 3x-5y=7\end{bmatrix}[/tex]
Multiply 2x+4y=1 by 3: 6x+12y=3
Multiply 3x-5y=7 by 2: 6x-10y=14
[tex]\begin{bmatrix}6x+12y=3\\ 6x-10y=14\end{bmatrix}[/tex]
subtracting the equations
[tex]6x-10y=14[/tex]
[tex]-[/tex]
[tex]\underline{6x+12y=3}[/tex]
[tex]-22y=11[/tex]
solve -22y for y
[tex]-22y=11[/tex]
Divide both sides by -22
[tex]\frac{-22y}{-22}=\frac{11}{-22}[/tex]
Simplify
[tex]y=-\frac{1}{2}[/tex]
[tex]y = -0.5[/tex]
For 6x+12y=3 plug in y = -1/2
[tex]6x+12\left(-\frac{1}{2}\right)=3[/tex]
[tex]6x-12\cdot \frac{1}{2}=3[/tex]
[tex]6x-6=3[/tex]
Add 6 to both sides
[tex]6x-6+6=3+6[/tex]
[tex]\frac{6x}{6}=\frac{9}{6}[/tex]
Simplification
[tex]x=\frac{3}{2}[/tex]
[tex]x = 1.5[/tex]
Therefore, the solution to the system of equations be:
x = 0.5, y = -0.5
