A store pays$66 for a model solar system and marks the price up by 20%. What is the amount of the mark-up?
y = 2x - 8 3x - 2y = 13
Answer:
{x,y} = {3,-2}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 2x - 8
// Plug this in for variable y in equation [2]
[2] 3x - 2•(2x-8) = 13
[2] -x = -3
// Solve equation [2] for the variable x
[2] x = 3
// By now we know this much :
x = 3
y = 2x-8
// Use the x value to solve for y
y = 2(3)-8 = -2
Solution :
{x,y} = {3,-2}
Write the equation of y-axis.
Answer:
The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it. Let P (x, y) be any point on the y-axis. Then clearly, for all position of P we shall the same abscissa 0 or, x = 0. Therefore, the equation of y-axis is x = 0.

In a college philosophy class during the fall semester, there were 323 students,42% of whom were male and the rest of whom were female. In the springsemester, the same number of females was in the class as in the fall, but there were only 298 total students in the class. In the spring, what percent of students were female?
A. 46%B. 58%C. 63%D. 92%
Using the percentage concept, it is found that the percentage of female students in the spring was of:
C. 63%
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
During the fall semester, 58% of 323 students were female, hence:
0.58 x 323 = 187.
Then, during the spring semester, the same amount out of 298, hence:
[tex]P = \frac{187}{298} \times 100\% = 63\%[/tex]

Andrea enjoys running. She keeps a daily journal to record how far she runs. She wears a pedometer to calculate the exact distance in kilometers
What did the total distance, in kilometers, that Andrea ran over the three days?
Answer:
14.225 kilometers.
Step-by-step explanation:
Monday 3.6
Tuesday 4.705
Wednesday 5.92
By using the addition operation, the total distance, in kilometers, that Andrea ran over the three days will be :
3.6 +4.705 +5.92=14.225
Hence, the total distance that Andrea ran over the three days = 14.225 kilometers.

The pair of figures to the right are similar. The area of one figure is given. Find the area of the other figure to the
nearest whole number.
Area of smaller parallelogram = 15 ft?
Answer:
135ft^2
Step-by-step explanation:
Area of the smaller parallelogram = Base * Height
15 = 3 * height
Height = 15/3
Height = 5ft
Since they are both similar
Height of the big parallelogram = 3(5) = 15ft
Area of the other parallelogram = 9 * 15
Area of the other parallelogram = 135ft^2

How do you find a slope and the Y intercept
How to find slope:
Divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
The actual formula for this is: (y2 - y1)/(x2 - x1).
How to find Y intercept
To find the y-intercept, plug 0 in for 'x' and solve for 'y'.
Ex. 2x + 3y = 12
So you plug in 0 for x therefore it becomes:
3y = 12
so, the y intercept is 4
Let me know if this is helpful :)
how do u solve problems like this ?
The first and second polygons are exactly the same, the only difference is that the second is bigger! If we look right the first polygon is 4 cm and the second is triple which means that we will have to triple the area of the First polygon to discover the area of the second polygon!
Resposta:if the first polygon is 4 cm long and the second 12 cm means that the second polygon has three times the area of the first polygon!
[tex](4 cm.3=12 cm)\\A-10 cm^{2}.3=30 cm^{2}[/tex]
the second polygon has [tex]30 cm^{2}[/tex] of area
[tex]A=30 cm^{2}[/tex]

the sum of the square of two consecutive positive integers is 85. Write a quadratic equation
Answer:
2x^2 + 2x - 83 = 0
Step-by-step explanation:
Consecutive integers differ by 1
Let the first number be x
The next will be (x+1)
The sum of the squares of these two numbers is 85
so we have;
x^2 + (x + 1)^2 =85
= x^2 + x^2 + 2x + 2 = 85
2x^2 + 2x + 2-85 = 0
2x^2 + 2x - 83 = 0

We have a 34 foot ladder leaning against a 30 foot buildingWe are asked to find the distance of the bottom ladder from bottom of the building.A ladder leaning against a object makes the ladder slanted so that means 34 is our hypotense.
The building height And distance of the bottom of ladder and building is our legs so our formula we use is
[tex] {30}^{2} + {x}^{2} = {34}^{2} [/tex]
[tex]900 + {x}^{2} = 1156[/tex]
[tex] {x}^{2} = 256[/tex]

Liu is making a rabbit pen. The graph shows where he plans to place it in his backyard. Each unit on the graph represents 1 foot.
1. What is the distance between points R and U? Explain how you found this distance.
2. Find the other three side lengths.
The length of the side between U and T is _______ feet.
The length of the side between T and S is _______ feet.
The length of the side between S and R is _______ feet.
3. The perimeter is the sum of the side lengths. What is the perimeter of the pen?
4. Does Liu have enough fence to make the pen? Why or why not?
Answer:
1. The distance between the points R and U is 4 feet
2. The length of the side between U and T is 3 feet
The length of the side between T and S is 4 feet
The length of the side between S and R is 3 feet
3.The perimeter of the pen is 14 feet
4. Yes
Liu has enough fence to make the Pen because he has more fence than the perimeter of the pen
Step-by-step explanation:
The 'x', and 'y' (x, y) coordinates of the points are;
R(5, 7), U(5, 3), S(8, 7), T(8, 3)
1. From the graph, the distance between the points R and U is given by the change in the values of the y-coordinate, given in feet, since the x-coordinate values are the same
Therefore, the distance between the points R and U = 7 ft. - 3 ft. = 4 ft.
2. Similarly, the length of the side between U and T is given by the change in the values of the x-coordinate, given in feet, since the y-coordinate values of U ant T are the same, as follows;
The length of the side between U and T = 8 ft. - 5 ft. = 3 ft.
Similarly the length of the side between T and S which have the same x-coordinate values is given as follows
The length of the side between T and S = 7 ft. - 3 ft. = 4 ft.
The length of the side between S and R which have the same y-coordinate values is given as follows;
The length of the side between S and R = 8ft. - 5ft. = 3ft.
3. The perimeter of the pen = Length R and U + Length U and T + Length T and S + Length S and R
∴ The perimeter of the pen = 4 ft. + 3 ft. + 4 ft. + 3 ft. = 14 ft.
4. The length of fencing Liu has = 16 feet (from internet source)
Therefore, the length of fence Liu has, 16 ft.is more than the length that make up the perimeter of the pen, 14 ft.
Therefore Liu has enough fence to make the Pen because the length of fence he has is more than the perimeter of the pen.

Pls help. Angle FGH is a straight angle .
The measure of angle FGJ is 145.
The measure of angle JGH is x.
What is the value of x.
Answer:
X is 35
Step-by-step explanation:
Since it’s a straight angle, the total measurement is 180 degrees. So if one angle is 145 then you subtract that from 180 and you will get 35 degrees.
the measurement of angle JGH is 35°
