A car is worth $300
Step-by-step explanation:
A board game allows players to trade and sell game pieces of equal value
Player 1 traded three cars plus $100 for a housePlayer 2 sold two houses and a car for $2300We need to find how much the car is worth
Assume that the car is worth $x and the house is worth $y
∵ Player 1 traded three cars plus $100 for a house
∴ 3 x + 100 = y
- Subtract 100 from both sides
∴ 3 x = y - 100
- Subtract y from both sides
∴ 3 x - y = - 100 ⇒ (1)
∵ Player 2 sold two houses and a car for $2300
∴ x + 2 y = 2300 ⇒ (2)
Now we have system of equation to solve it
Multiply equation (1) by 2 to eliminate y
∵ 6 x - 2 y = - 200 ⇒ (3)
- Add equations (2) and (3)
∴ 7 x = 2100
- Divide both sides by 7
∴ x = 300
A car is worth $300

Let x = number of white marbles and y = number of yellow marbles.
x + y = 57 => x = 57 - y
Also, x = 3 + 5y
Substitute x for y.
57 - y = 3 + 5y => 57 - 3 = 54 = 6y
So, y = 9
Since x (our answer) = 3 + 5 (9),
x = 48.
Check: 48 + 9 = 57 total

A rectangular garden measures 5m by 7m. Both dimensions are to be extended by the same amount so that the area of the garden is doubled. By how much should the dimensions increase
Final answer:
To double the area of the rectangular garden, the dimensions should increase by 5 meters.
Explanation:
To double the area of the rectangular garden, we need to find the increase in dimensions that will result in double the original area. The original dimensions are 5m by 7m, so the original area is 5m x 7m = 35 square meters. To double this area, the new area should be 35 square meters x 2 = 70 square meters. Let's assume the increase in dimensions is 'x'. The new dimensions will be (5m + x) by (7m + x). We can set up the equation:
(5m + x)(7m + x) = 70 square meters
Expanding and simplifying the equation, we get:
35m + 5x + 7x + x^2 = 70 square meters
Combining like terms, we have:
x^2 + 12x + 35 = 70 square meters
Next, we rearrange the equation into standard form:
x^2 + 12x + 35 - 70 = 0
Simplifying further, we get:
x^2 + 12x - 35 = 0
Now we can solve this quadratic equation by factoring or using the quadratic formula. Factoring the equation gives us:
(x + 7)(x - 5) = 0
Setting each factor equal to zero, we have:
x + 7 = 0 or x - 5 = 0
Solving for 'x', we get:
x = -7 or x = 5
Since a negative value doesn't make sense in this context, we can conclude that the dimensions should increase by 5 meters.

The value of x in the equilateral triangle is 3 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the perimeter of any planer figure except a circle is the sum of the lengths of all the sides and we also know that an equilateral triangle has equal sides and equal angles.
∴ We can equate any of the two sides of the given equilateral triangle.
So, 5x = 6x - 3.
5x - 6x = - 3.

Answer:
ABCD and EFGH
ABCD and PQRS (or EFGH and PQRS)
Dilate by a scale factor of 3
Step-by-step explanation:
Congruent means they have the same shape and size.
Similar means they have the same shape, but not necessarily the same size.
The orientation (rotation angle) or position do not matter.
EFGH is reflected and rotated, so it maintains the same shape and size as ABCD. Therefore, they are congruent.
PQRS is scaled and translated, so it has the same shape, but different size than ABCD. Therefore, they are similar but not congruent.
Also, PQRS is similar to EFGH, but not congruent.
To make EFGH congruent to PQRS, we need to make it the same size. So we need to scale EFGH by a factor of 3.
The ratio of men to women working for a company is 2 to 3. If there are 42 women for the company what is the total number of employees
Answer:
70 people
Step-by-step explanation:
Final answer:
The total number of employees at the company is calculated using the given ratio of men to women, 2 to 3, along with the information that there are 42 women. By converting the ratio into actual numbers, we find that there are 28 men and 42 women, totaling 70 employees.
Explanation:
The question asks about the total number of employees in a company given the ratio of men to women and the number of women. To find the answer, we will use the ratio of men to women, which is 2 to 3, and the information that there are 42 women working for the company.
Since the ratio of men to women is 2 to 3, this implies there are 2 men for every 3 women in the company.If there are 42 women, and the ratio of women to the total number of employees is 3 parts, we can find out how many parts represent the men. One part would be 42 women divided by 3, which is 14 men.According to the ratio, there are 2 parts for men, therefore, 2 parts times 14 give us 28 men.To find total number of employees, we add the number of men and women, which is 28 men plus 42 women, equating to 70 employees.0.5 to the power of x equals 128. Find x
The value of x, that solves the equation 0.5 to the power of x equals 128, is approximately -7. This is found first by rearranging the equation into the logarithmic form, then using the change of base formula to solve for x.
Explanation:The question is asking to solve the equation 0.5 to the power of x equals 128 for the value of x. In order to solve this, we can use the properties of logarithms. Firstly, re-write the equation in log form as log (base 0.5) 128 = x.
We can use the change of base formula which is logba = logca / logcb, where c can be any positive value different than 1 (usually we use 10 or e). If we apply this to our formula it becomes: x = log 128 / log 0.5.
By calculation, x is approximated to -7. This means that when you raise 0.5 to the power of -7, you will get 128.

Fred buys a binder for $4.50 and six reams of paper. Latasha buys an ink cartridge for $17.50 and four reams of paper. Both spend the same amount of money. What is the price of one ream of paper?
Answer:
The the price of one ream of paper is $6.5.
Step-by-step explanation:
Here, Let us assume the cost of one ream of paper = $ m
The money spent by Fred:
The money spent on a binder = $4.50
The money spent on 6 ream of papers = 6 x ( cost of 1 ream )
= 6 x ($m) = 6 m
⇒The total money Fred spent = Money spent on (binder + 6 ream of papers)
= 4.50 + 6 m ....... (1)
The money spent by Latasha:
The money spent on a cartridge = $17.50
The money spent on 4 ream of papers = 4 x ( cost of 1 ream )
= 4 x ($m) = 4 m
⇒The total money Latasha spent = Money spent on (cartridge + 4 ream of papers)
= 17 .50 + 4 m .... (2)
Also, Both spend the same amount of money
⇒4.50 + 6 m = 17 .50 + 4 m ( from (1) and (2))
or, 6 m - 4 m= 17. 50 - 4, 50
or, 2 m = 13
or, m = 13/ 2 = 6.5
So, the value of m = $6.5
Hence, the the price of one ream of paper is $6.5.

Jamie and Stella are saving money to sign up for a school trip to Washington, D.C. In order to sign up for the trip, they must pay $600 upfront. Jamie earns his money by washing cars for $25 each. Stella earns her money by making pecan pies for $15 each. Jamie earns more money than Stella does because Stella only has enough supplies to make 40 pies. let x represent the number of cars Jamie washes. Let y represent the number of pies Stella makes.
Part 1: Write a constraint (an inequality) to represent how much money Jamie needs for his trip.
Part 2: Write a constraint (an inequality) to represent how much money Stella needs for her trip.
Part 3: Write a constraint (an inequality) to represent the limitations of Stella's supplies.
Part 4: Can Stella afford to sign up for the trip with the money she earns? Explain your answer and show any work that might support your answer.
Answer:
Jamie: His inequality would look like this: 25x >= 600
Stella: Her inequality would look like this: 15y >= 600
Her limitations would be listed as: y=40
Yep. Stella has plenty of money by baking 40 pies; $600.
We can back that up by breaking this down. So. We know that it cost $600 to pay upfront and Jamie makes $25 per car he washes. Stella would make $15 for every pie she baked. So simply, let x represent the number of cars Jamie washes. Let y represent the number of pies Stella makes. Easy.
Since the cost for washing one car is $25
Now, in order to sign up for the trip, money obtained from car washing must be greater than or equal to $600. We know that. Now, lets see their profit margins.
Since the cost for making one pie is $15
Therefore, the cost of making y pies is 15y.
Now, in order to sign up for the trip, money obtained from pie making must be greater than or equal to $600 so with that being the case... 15y>=600
We all know the maximum number of pies that Stella can make is 40. So, the value of can't exceed 40 and must be less than or equal to 40. So.... y<=40
Bam.
In order to sign up for the trip, Stella's total earning must be at least $600. So, is the minimum condition for signing up for the trip. Now, let us solve the above equation for . So our end project looks like this: 15y = 600 y = 600/15 = 40
The minimum number of pies required for signing up for the trip is 40 and luckily that's the maximum supply Stella has for pies. Therefore, she can sign up for the trip by making all the 40 pies and earning a total of 600 dollars.

The ages of five friends are 20,31,28,31 and 25. How many of the friends are older than the average (arithmetic mean) age?
Answer:
3 friends
Step-by-step explanation:
The mean age is 27 so 3 friends are above that age.
The average age of the friends is 27. Only two of the friends, both aged 31, are older than the average age.
Explanation:To find out how many of the friends are older than the average age, we need to first find the arithmetic mean of the ages. We do this by adding up all the ages and dividing by the number of ages. So, (20+31+28+31+25)/5 = 27. Once we have the average, we can see that the ages of 31 and 31 are larger than the average of 27. Therefore, there are 2 friends whose ages are older than the average.

I order to be able to compare quantities that come in fraction form, the best is to write all of them as equivalent fractions with the same denominator. That way just looking at the magnitude of the numerators will allow us to give the answer.
the fractions to consider are: [tex]\frac{3}{4} \,,\, \frac{2}{6} \,, \, and\, \frac{8}{12}[/tex]
so the denominators in question are: 4, 6, and 12.
We see that 12 is the Least Common Denominator (LCD) of these three, since 4 divides perfectly 12, 6 divides 12 perfectly, and 12 divides itself perfectly as well.
Now, the initial fractions can be re-written with equivalent fractions showing denominator 12.We do such by multiplying numerator and denominator of the first fraction by "3" in order to get a "12" in the denominator. By multiplying the second fraction by 2 in numerator and denominator to get a "12" in the denominator. Notice that we don't need to modify the third fraction since it is already expressed with denominator 12:
[tex]\frac{3}{4} \,,\, \frac{2}{6} \,, \, and\, \frac{8}{12}=\\=\,\frac{9}{12} \,,\, \frac{4}{12} \,, \, and\, \frac{8}{12}[/tex]
Therefore, the greatest of these is the first fraction, that shows a "9" in the numerator (the largest of the three numerators)

An ice cream factory makes 350 quarts of ice cream in 2 hours. How many quarts could be made in 36 hours? What was that rate per day?
Answer:
36 hours - 6,300
24 hours - 4,200
In 36 hours, 6300 quarts of ice cream could be made. The rate per day would be 6300 quarts per day.
350 quarts of ice cream are made in 2 hours. To find out how many quarts could be made in 36 hours, we can set up a proportion: 350 quarts / 2 hours = x quarts / 36 hours. Solving for x gives us 6300 quarts in 36 hours. To find the rate per day, we divide the total quarts made in 36 hours by the number of days: 6300 quarts / 1 day = 6300 quarts per day.

4. Given ABC with vertices at A(1,-4), B(-1,-2), and C(-2,-5), prove or disprove that ABC is isosceles
Answer: ABC is isosceles
Step-by-step explanation:
The coordinate of points given are:
A(1,-4)
B(-1, -2 )
C ( -2 , -5 )
For ABC to be isosceles , then AB must be equal to BC or AB = AC
The next thing to do is to find the value of AB , BC and AC using the formula for finding distance between two points which is given by:
D = [tex]\sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}[/tex]
Calculating AB first , we have
[tex]\sqrt{(-1-1)^{2}+(-2+4)^{2} }[/tex]
= [tex]\sqrt{4+4}[/tex]
=[tex]\sqrt{8}[/tex]
Therefore:
AB = [tex]\sqrt{8}[/tex]
Calculating BC , we have :
D = [tex]\sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}[/tex]
D = [tex]\sqrt{(-2+1)^{2}+(-5+2)^{2} }[/tex]
D = [tex]\sqrt{10}[/tex]
Therefore:
BC = [tex]\sqrt{10}[/tex]
Calculating AC , we have :
D = [tex]\sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}[/tex]
D = [tex]\sqrt{(-2-1)^{2}+(-5+4)^{2} }[/tex]
D = [tex]\sqrt{10}[/tex]
Therefore:
AC = [tex]\sqrt{10}[/tex]
Since AC = BC then triangle ABC is isosceles
