John is selling tickets to an event. Attendees can either buy a general admission ticket, x, or a VIP ticket, y. The general admission tickets are $70 and the VIP tickets are $80. If he knows he sold a total of 29 tickets and made $2,130, how many of each type did he sell?
Step-by-step explanation:
x+y=29...because x and y means how many tickets they have
and if normal 1 ticket is 70...then x number of tickets are $70x.
and
1 VIP ticket is 80...then y number of tickets are $80y..got that?...sum of all earned by selling tickets equal to $2130
so...
70x+80y=2130
so...equations are
x+y=29
70x+80y=2130
solve these equations.i did the hard part...you will get the answer...if u dont know hot to solve this comment me...
A rectangular yard measuring 35ft and 45ft is bordered (and surrounded) by a fence. Inside, a walk that is 4ft wide goes all the way along the fence find the area of this walk
First, calculate the area of the rectangular yard.

The equation v=-2000+20000 describes the value in dollars of a certain model of car after it is t years old. If a car is worth $10,000, substitute 10,000 into the equation to find the age of the car.
I'm assuming the equation is:
v = -2000t + 20,000 because the value of a car decreases with time
v = worth of the car
t = number of years
Since you know the value of v = 10,000, substitute or plug in 10,000 for v in order to find t
v = -2000t + 20,000 Substitute 10,000 into v [To find t, you need to get the variable by itself to one side of the equation.]
10,000 = -2000t + 20,000 Subtract 20,000 on both sides
-10,000 = -2000t Divide -2000 on both sides to get t by itself [negative divided by a negative results in a positive]
5 = t

Are 4x and 15 + x equivalent expressions
Final answer:
The expressions 4x and 15 + x are not equivalent as they yield different results for the same value of x.
Explanation:
The expressions 4x and 15 + x are not equivalent. Equivalence between two expressions means that for any value of the variable(s) involved, the expressions yield the same result. To determine if these expressions are equivalent, you can compare them for different values of x. For instance, if x is 1, 4x yields 4, whereas 15 + x yields 16, which are not the same. Thus, we can say that the expressions 4x and 15 + x are not equivalent as they produce different results for the same values of x.
Two cars are 190 miles apart and travel toward each other along the same road. They meet in 2 hours. One car travels 5 miles per hour faster than the other car. What is the average speed of each car?
The speed of slower car is 45 mph and faster car is 50 mph.
Step-by-step explanation:
Given,
Distance covered by both cars = 190 miles
Time taken by both of them = 2 hours
Let,
x be the speed of slower car.
Speed of faster car = x+5
Combined speed = x+x+5 = 2x+5
We know that;
Distance = Speed * Time
[tex]190=(2x+5)*2\\190=4x+10\\4x=190-10\\4x=180\\[/tex]
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{180}{4}\\x=45[/tex]
Speed of slower car = 45 miles per hour
Speed of faster car = 45+5 = 50 miles per hour
The speed of slower car is 45 mph and faster car is 50 mph.

The problem given is a relative speed problem in mathematics. By solving the equation, we find that the slower car travels at 45 mph and the faster car travels at 50 mph.
Explanation:This is a
problem of relative speed
in
mathematics
. Let's consider the speed of the slower car as 'x' miles per hour. The faster car is travelling 'x+5' miles per hour. Since they are moving towards each other, the sum of their speeds equals the total distance divided by the total time, that is (x + (x + 5)) = 190/2. Simplifying the equation, we get 2x + 5 = 95. Solving further, we get x = 45 miles per hour. Therefore, the slower car is travelling at 45 mph and the faster car is travelling at 50 mph.

A new car is purchased for 24000 dollars. The value of the car depreciates at 6.75% per year. To the nearest year, how long will it be until the value of the car is 15500 dollars?
Final answer:
To the nearest year, it will take about 6 years for the value of the car to reach $15,500.
Explanation:
To find how long it will take for the value of a car to depreciate to $15,500, we can set up an equation using the formula for exponential decay: V = P[tex](1 - r)^t[/tex], where V is the final value, P is the initial value, r is the depreciation rate, and t is the time in years.
Plugging in the given values, we have 15500 = 24000[tex](1 - 0.0675)^t[/tex]. To solve for t, we can take the logarithm of both sides:
log(15500) = log(24000[tex](1 - 0.0675)^t)[/tex]
t * log(1 - 0.0675) = log(15500/24000)
t = log(15500/24000) / log(1 - 0.0675)
Using a calculator, we find that t is approximately 5.54 years. Rounding to the nearest year, it will take about 6 years for the value of the car to reach $15,500.

Dave ordered dinner for a party of 10 people. Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each. what was the average cost of each dinner at Dave's party?
Answer:
The average cost of each dinner at Dave's party is $5.79.
Step-by-step explanation:
Given:
Dave ordered dinner for a party of 10 people.
Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each.
Now, to find the average cost of each dinner at Dave's party.
So, we get the total amount for the dinner:
Three people ordered the $4.75 chicken dinner.
[tex]4.75\times 3=14.25[/tex]
Two people ordered the $4.95 fish dinner.
[tex]4.95\times 2=9.90[/tex]
Five had the beef dinner at a cost of $6.75.
[tex]6.75\times 5=33.75[/tex]
Total amount of dinner = [tex]14.25+9.90+33.75=\$57.90.[/tex]
Now, to get the average cost of each dinner of 10 people we divide the total amount of dinner by 10:
[tex]57.90\div 10[/tex]
[tex]=\$5.79.[/tex]
Therefore, the average cost of each dinner at Dave's party is $5.79.
Final answer:
To find the average cost per dinner at Dave's party, calculate the total cost of each type of dinner and sum them up to get the total cost. Then, divide the total cost by the number of guests to obtain the average cost. The average cost per dinner is $5.79.
Explanation:
To calculate the average cost of each dinner at Dave's party, first calculate the total cost of all dinners combined by multiplying the number of each type of dinner by its price and then adding up the totals:
Chicken dinner cost: 3 dinners × $4.75 = $14.25
Fish dinner cost: 2 dinners × $4.95 = $9.90
Beef dinner cost: 5 dinners × $6.75 = $33.75
Next, add all the costs together to get the total cost of the dinners:
Total cost = $14.25 + $9.90 + $33.75 = $57.90
Now, divide the total cost by the number of guests to find the average cost per dinner:
Average cost = Total cost ÷ number of guests
Average cost = $57.90 ÷ 10 = $5.79
So, the average cost per dinner at Dave's party is $5.79.

Write an equation from the following points (plug in the numbers you would use for "m" and "b"):
(3, 9) and (6, 13)
Answer:
[tex]y =\fracc{4}{3}x+5[/tex]
m=4/3 and b=5
Step-by-step explanation:
We want to find the equation of the line passing through (3,9) and (6,13).
We determine the slope using:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
Let:
[tex](x_1=3,y_1=9), (x_2=6,y_2=13)[/tex]
We substitute the points to get:
[tex]m = \frac{13 - 9}{6 - 3} = \frac{4}{3} [/tex]
We now use the formula:
[tex]y-y_1=m(x-x_1)[/tex]
We substitute to get:
[tex]y - 9 = \frac{4}{3} (x - 3)[/tex]
Multiply through by 3 to get;
[tex]3y - 27 = 4(x - 3)[/tex]
We expand further to get:
[tex]3y - 27 = 4x - 12[/tex]
This implies that:
[tex]4x - 3y = - 15[/tex]
We solve for y to get:
[tex]y =\fracc{4}{3}x+5[/tex]
Therefore m=4/3 and b=5
