A board game allows players to trade and sell game pieces of equal value. Player 1 traded three cars plus $100 for a house. Player 2 sold two houses and a car for $2300. How much is a car worth?
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

Answer:
MOP = DAB
Step-by-step explanation:
the sides have to be matched up as well. the side with only one dash (MO) has to correspond with the side with one dash from the other triangle (DA). Thus, the letters in the sequence (MOP) have to match up in the same order (DAB)
The correct congruency statement with regards to the congruence of the triangles is the fourth statement
ΔMOP ≅ ΔDABThe details of the steps by which the congruence statement can be found can be presented as follows;
The marks on the segment indicates;
PO is congruent to BA
MO is congruent to DA
PM is congruent to BD
Therefore, the triangle MOP is congruent to the triangle DAB
The order in which the markings on the triangles are located can also be used to find the correct congruence statement
The name of the triangle MOP indicates that the vertice of the triangle between the segment with three marklings, III, and the segment with one marking, I, is considered first, which is the vertice M and D on each triangle
The next mentioned vertice is the vertice between the segment with one marking and the segment with two markings, which is the vertice O and A on each triangle
The third considered vertice is the third vertice on both triangles, which corresponds to the vertice P and B on each triangle
The congruency statement is therefore ΔMOP ≅ ΔDAB

A corporate team-building event costs $1, plus an additional $1 per attendee. Write an equation that shows the relationship between the attendees x and the cost y.Write your answer as an equation with y first, followed by an equals sign.
The total cost y of a corporate team-building event can be expressed by the equation y = 1 + 1x, where x represents the number of attendees. This equation includes both the fixed and variable costs.
To determine the cost y of a corporate team-building event based on the number of attendees x, we need to include both the initial fixed cost and the variable cost per attendee.
The fixed cost of the event is $1, and the variable cost per attendee is also $1. The total cost can be expressed using the following equation:
y = 1 + 1x
Here:
y represents the total cost of the event.x represents the number of attendees.The term '1' before the plus sign is the initial fixed cost, and '1x' is the variable cost for the attendees.For example, if there are 5 attendees, the total cost would be calculated as:
y = 1 + 1(5) = 1 + 5 = 6 dollars

At 8:00 AM a bicyclist departed city A, heading towards city B at a rate of 20 km/h. After traveling for 4 hours he stopped for an hour break. At the same time, a biker left city A traveling in the same direction at the rate of 50 km/h. will give brainliest plz dont troll
Answer:
Biker will catch the cyclist after 2 hr and 40 min.
Step-by-step explanation:
Given:
Speed of Bicyclist = 20 km/h
Travelling time = 4 hrs
∴ Distance = Speed × Time = [tex]20\times4=80 \ km[/tex]
Also he rest for 1 hr.
So we can say that, after 5 hrs Bicyclist is 80 km ahead when the biker Started.
Now Biker rate is given 50 km/h
And Bicyclist rate is 20 km/h
So, for each hour, biker advances 50 - 20 = 30 kilometers
now bicyclist distance is 80 km
and biker advances 30 per hour.
Therefore to catch up bicyclist at 80 km i.e time taken to reach 80 km with 30 km rate per hour.
Time = [tex]\frac{80}{30}=2 \frac{2}{3} h[/tex]
Hence, Biker will catch the cyclist after 2 hr and 40 min.

How to rewrite 11x+13y=8 in slope intercept form
Answer
y=-\frac{11}{13}x+\frac{8}{13}
Step-by-step explanation:
Answer:
y = -(11/13)x + (8/13)
Step-by-step explanation:
recall slope intercept form of a linear equation takes the general form:
y = mx + b
In this case, simply rearrange the given equation such that it looks like the general equation above.
11x+13y=8 (subtract 11x from both sides)
13y = -11x + 8 (divide both sides by 13)
y = -(11/13)x + (8/13) (answer)

mrs.jones rented a truck to move to a new apartment the regular price of a truck rental is 150 mrs.jones has a 20% off coupon she wants to know the sale price of truck rental
Answer:
The sell price of the truck rental after applying the coupon of 20 % is $ 120 .
Step-by-step explanation:
Given as :
The regular rented price for the truck = $ 150
The discount as off coupon = 20 %
Let The sell price for truck after discount = x
So , Discount % = [tex]\dfrac{\textrm market price - \textrm Selling price}{\textrm market price}[/tex]
Or, 20 % = [tex]\dfrac{\textrm 150 - \textrm x}{\textrm 150}[/tex]
Or, [tex]\dfrac{x}{150}[/tex] = 1 - [tex]\dfrac{20}{100}[/tex]
Or, [tex]\dfrac{x}{150}[/tex] = [tex]\dfrac{100 - 20}{100}[/tex]
or, [tex]\dfrac{x}{150}[/tex] = [tex]\dfrac{80}{100}[/tex]
∴ x = [tex]\frac{80\times 150}{100}[/tex]
I.e x = 8 × 15
Or, x = 120
Hence the sell price of the truck rental after applying the coupon of 20 % is $ 120 . Answer

joe bought g: gallons of gasoline for $2.85 per gallon and c: cans for oil for 3.15 dollars.
Part A:what expression can be used go determine the total amount joe spent on gasoline and oil?
part B:if he bought 8.4 gallons of gasoline and 6 cans of oil, how much will he have spent in all?
please help! thank you :D
The expression to determine the total amount Joe spent on gasoline and oil is 2.85 * g + 3.15 * c. If Joe bought 8.4 gallons of gasoline and 6 cans of oil, he will have spent 42.84 dollars in total.
Explanation:Part A: To determine the total amount Joe spent on gasoline and oil, we need to calculate the cost of gasoline and the cost of oil separately, and then add them together.
The expression to calculate the cost of gasoline is: 2.85 * g, where 'g' represents the number of gallons of gasoline Joe bought.
The expression to calculate the cost of oil is: 3.15 * c, where 'c' represents the number of cans of oil Joe bought.
Therefore, the expression to determine the total amount Joe spent is: 2.85 * g + 3.15 * c.
Part B: If Joe bought 8.4 gallons of gasoline and 6 cans of oil, we can substitute these values into the expression we derived in Part A.
The total amount Joe spent can be calculated as follows:
Total amount spent = 2.85 * 8.4 + 3.15 * 6
Simplifying the expression:
Total amount spent = 23.94 + 18.90
Total amount spent = 42.84 dollars

Two standard dice are rolled and their face values multiplied. What is the probability that the product is prime or ends in a 5?
Final answer:
To find the probability that the product of two standard dice is prime or ends in a 5, we need to count the favorable outcomes and divide it by the total number of possible outcomes. The probability is 1/4 or 0.25.
Explanation:
To find the probability that the product of two standard dice is prime or ends in a 5, we need to count the favorable outcomes and divide it by the total number of possible outcomes.
To have a prime product, the possible combinations are: (2,2), (2,3), (2,5), (3,2), (3,3), (3,5), (5,2), (5,3), (5,5)
To have a product that ends in 5, the possible combinations are: (1,5), (2,5), (3,5), (4,5), (5,5), (6,5).
The total number of favorable outcomes is 9.
When two dice are rolled, there are 36 total possible outcomes (6 possible outcomes for the first die multiplied by 6 possible outcomes for the second die).
Therefore, the probability that the product is prime or ends in a 5 is 9/36, which simplifies to 1/4 or 0.25.

Answer:
Brett is 62 years old, Carl is 70 years old and Mark is 80 years old.

The value of y varies directly with x. If x=1/2, then y=40. Which of the following equations represents this situation?
A. x=20y
B. y=20x
C. y=80x
D. x=80y
Option C: y = 80x is the right answer
Step-by-step explanation:
Varying directly means that the increase/decrease in one quantity will cause increase/decrease in other quantity.
If y varies directly with x it is given by::
y ∝ x
When the proportionality symbol is removed, a proportionality constant is introduced
y = kx
If x = 1/2 and y = 40
then
[tex]40 = k * \frac{1}{2}\\k = 40*2\\k = 80[/tex]
Putting the value of k, we get
y = 80x
Hence,
Option C: y = 80x is the right answer
