The purchasing cost of each game costs $1.55 and each song costs $1.89 according to the given equation.
What are variables?A variable is a symbol or character that represents a value or set of values in mathematics and computer programming that can change and take on different values depending on the context.
The given problem can be solved using a system of equations.
The first formula, 5g + 8s = 22.87, represents the total cost of games and songs purchased by Cedro.
The second formula, 7s + 4g = 18.89, represents the total cost of games and songs purchased by Benita.
5g = 22.87 - 8s
g = (22.87 - 8s)/5.
We can now substitute this expression for g into the second equation and solve for s. So we have:
7s + 4((22.87 - 8s) / 5) = 18.89
On expanding and solving this equation for s we get:
7s + (91.48 - 32s) = 18.89
32s + 7s = 73.59
39s = 73.59
s = 1.89
By substituting the value of s into the equation 5g = 22.87 - 8s gives
5g = 22.87 - 8(1.89)
5g = 22.87 - 15.12
5g = 7.75
g = 1.55

Sydney says that if all of the side lengths of a cube are doubled, the volume of the cube will also double. Is she correct? Explain.
Answer:
no, it's not correct
Step-by-step explanation:
volume or the cube = L³
so if we doubled the side lengths
They would be 2L
then the volume= (2L)³ = 8L³
so that would make the volume 8 times the first value not double
Perry learned to play a total of 18 piece over the coure of 9 week of piano leon. After 12 week of piano leon, how many total piece will Perry be able to play? Solve uing unit rate
In a course of 12 weeks, Perry will be able to play a total of 25 pieces of the piano Leon.
A total of 18 pieces of piano are learnt by Perry in a course of 9 weeks.
By using simple algebra, we can find the number of pieces that will be played by Perry in one week,
So, we can write, The learing speed,
Number of piano pieces learnt = Weeks
19 pieces = 9 weeks
Learning speed = 19/9 Pieces per week
So, the number of pieces learnt in 12 weeks is,
Number of pieces learnt = 19/9 x 12
Number of pieces learnt = 25.22
Number of pieces learnt = 25
So, Perry will be able to play 25 pieces.

Explanation:
Each line is equal to 180 degrees so 180-68 is 112 f and a should be the same degree because of the way the line is slanted. E and c will be the inverse of d and 68.
The price of a particular stock is represented by the linear equation y = negative 0.91 x + 103.47, where x represents the number of weeks the stock has been owned and y represents the price of the stock, in dollars. If this relationship continues, what is the price of the stock after it has been owned for 12 weeks?
Answer:
Step-by-step explanation:
We have, C(x) = 0.005x3 – 0.02x2 + 30x + 5000
Clearly, the marginal cost, MC (x) = \(\frac{d}{d x}\)C(x)
= \(\frac{d}{d x}\)(0.005x3 – 0.02x2 + 30x + 500)
= 0.005 × 3x2 – 0.02 × 2x + 30 + 0
= 0.015x2 – 0.04x + 30
Now, marginal cost when 3 units arei produced
MC(3)= 0.015(9) – 0.04(3) + 30
= 0135 – 0.12 + 30= 30.015

A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is 29 ft. long and 19 ft. wide. If the gardener wants to build a fence around the garden, how many feet of fence are required? (Use the value 3.14 for pi, and do not round your answer. Be sure to include the correct unit in your answer.)
Answer:
141.6925 [tex]ft^{2}[/tex]
Step-by-step explanation:
Area of rectangle = LW
A = 29 x 19 = 551 [tex]ft^{2}[/tex]
Semicircle = [tex]\frac{\pi r^{2} }{2}[/tex]
[tex]\pi[/tex] = 3.14
r = 19/2 = 9.5
[tex]\frac{(3.14)(9.5^{2}) }{2}[/tex]
(9.5)^2 = 90.25
3.14 x 90.25 = 283.385
283.385/2 = 141.6925 [tex]ft^{2}[/tex]

Which angles are alternate exterior angles?
1. EFH and BCF
2. EFH and DCA
3. EFH and EFC
4. EFH and BCA
∠EFH and ∠ACD are angles of alternate exterior angles in the figure as alternate external angles are those that are generated on the outer side of the parallel lines .
what are angles ?When two straight lines connect at a 90° angle or are perpendicular to one another, an angle is formed. The symbol denotes a right angle. In the picture up above, many right angle formations are visible. Shapes include the correct angles. Triangles classified as right triangles have one of their internal angles at a 90 degree right angle. The three interior angles of a triangle add up to 180 degrees, so the three interior angles of a right triangle must always add up to 90 degrees because one of them is always 90 degrees.
given
The pair of angles known as alternate external angles are those that are generated on the outer side of the parallel lines but on the transverse side.
sum up to 180 degrees, you can calculate the size of the inner angle adjacent to it if you know the size of the outer angle (since together they are the angle on a straight line). The internal angles at the other two vertices are added to create the outer angle of a triangle.

How do you simplify 3 ratios?
To simplify 3 ratios, divide each part of the ratio with the same amount and keep diving numbers in the ratio until they are as small as possible but they remain as whole numbers.
To simplify or reduce a fraction, first, we need to find a common factor between the ratio numbers. When we have multiple ratio numbers, we must find a common factor between all of them.
The greatest factor between all the ratio numbers (greatest common factor) will be utilised to divide or reduce the ratios down to their lowest form.
For example reduce the ratio 350: 250: 125
The first step is to determine a common factor between all of the ratio numbers. In this example, we can see that all of the numbers end in either 5 or 0. This means that each number should have 5 as a factor.
If numbers are large and we are not sure of the greatest common factor between them all, we can reduce by a common factor and then reduce again.
Now divide each number by 5 and see what we get.
350/5: 225/5: 125/5
70: 45: 25
When we divide each one by 5 again, we can see that each number again ends in 5 or 0 which means that 5 is still a factor of each number.
Now divide each number by 5 again and get a final ratio of 14: 9: 5.
70/5: 45/5: 25/5

Solve the following system of equations. Enter the y-coordinate of the
solution. Round your answer to the nearest tenth.
5x+2y=21
- 21+ 6v=-34
To find the y-coordinate of the solution, we can substitute in this value for y and round it to the nearest tenth: y = -2.2
What exactly does a coordinate system mean?system of coordinates, Arrangement of reference lines or curves for locating points in space The Cartesian (named for René Descartes) system is the most popular one in two dimensions.
To solve for y in the equation 5x + 2y = 21, we can start by isolating y on one side of the equation. To do this, we can subtract 5x from both sides of the equation:
5x + 2y = 21
5x - 5x + 2y = 21 - 5x
2y = 21 - 5x
To solve for y, we can then divide both sides of the equation by 2:
2y = 21 - 5x
y = (21 - 5x) / 2
To solve for y in the equation -21 + 6y = -34, we can start by isolating y on one side of the equation. To do this, we can add 21 to both sides of the equation:
-21 + 6y = -34
-21 + 21 + 6y = -34 + 21
6y = -13
To solve for y, we can then divide both sides of the equation by 6:
6y = -13
y = -13/6
y = -2.1666666666666665
To find the y-coordinate of the solution, we can substitute in this value for y and round it to the nearest tenth:
y = -2.2
So, the y-coordinate of the solution is -2.2.

You decide you want to go snowboarding for the day and you have to figure out your budget. Tickets are $75.00 per day and there is a 5% convenience charge when you order your ticket. You also have to pay for a bus ticket that is $12 for the day. You mom gives you a 15% off coupon that applies to the lift ticket only (not the bus). What is the total cost for your fun day out? (round to the nearest hundredth)
The total cost for your fun day out is $23.82.
What is percentage?In mathematics →
a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".Given is that you decided to go snowboarding for the day and you have to figure out your budget. Tickets are $75.00 per day and there is a 5% convenience charge when you order your ticket. You also have to pay for a bus ticket that is $12 for the day. You mom gives you a 15% off coupon that applies to the lift ticket only.
Assume that the total cost for your fun day out is ${x}. Then, we can write the equation as -
{x} = 15% of (75 + {5% of 75}) + 12
{x} = 15% of (75 + {5/100 x 75}) + 12
{x} = 15% of (75 + {1/20 x 75}) + 12
{x} = (15/100) x (75 + 75/20) + 12
{x} = (3/20 x 78.75) + 12
{x} = 11.82 + 12
{x} = 23.82
Therefore, the total cost for your fun day out is $23.82.
