Five times the second of three consecutive odd integers is thirteen less than three times the sum of the first and third integers. Find the largest odd number.

Answers

Answer: 15

Step-by-step explanation:

suppose;  three consecutive odd integers are x; x + 2; x+ 4 (x is a odd integer)

because Five times the second of three consecutive odd integers is thirteen less than three times the sum of the first and third integers

=> 5(x + 2) = 3( x +x +4) - 13

<=> 5x + 10 = 6x + 12 - 13

<=>6x - 5x = 10 + 13 - 12

<=> x = 11

=> the largest odd number is 11 + 4 = 15

The largest of the three consecutive odd integers which could be written as a, a+2 and a + 4 is 15

Let the integers be : a, a + 2, a + 4

Creating a mathematical equation using the scenario given.

5(a + 2) = 3(a + (a + 4)) - 13

Open the bracket bracket

5a + 10 = 3(2a + 4) - 13

5a + 10 = 6a + 12 - 13

5a + 10 = 6a - 1

Collect like terms

5a - 6a = - 1 - 10

-a = - 11

a = 11

The largest integer = a + 4 ; 11 + 4 = 15

Therefore, the largest of the consecutive odd integers is 15

Find the values of x and y.
X= __
Y= __

Answers

Answer:

x = 20

y = 100

Step-by-step explanation:

To figure out x do this.

3x + 2x = 7x - 40 (collect like terms)

5x = 7x -40 (subtract 7x on both sides)

-2x = -40 (divide by -2 on both sides)

x = 20

Plug in to get y

Since 7x - 40 and y are vertical they equal the same amount

7(20) - 40 = y (multiply 7 by 20)

140 - 40 = y (collect like terms)

100 = y

Describe the end behavior of a 9th degree polynomial with a negative leading coefficient??

Answers

Answer:

Up left, down right

Step-by-step explanation:

First, polynomials with odd degrees will have end behaviors in two different directions.

Since the leading coefficient is negative, the end behavior will be up left and down right.

So, the end behavior is up left, down right.

The end behavior of a 9th-degree polynomial with negative leading coefficients is up left, downright.

We have to determine

Your family buys tickets for the Ranger game. Each ticket costs $16. You also have to pay for parking. After buying 4 tickets, your total bill is $96.50.
a) How much did you pay for parking?
b) Write an equation that gives your total bill (in dollars) as a function of the number of tickets you buy. Be sure to define your variables!
c) How many tickets could you buy with $250 if you also have to pay for parking?​

Answers

Part (a)

Answer: $32.50

--------------------

Work Shown:

Each ticket costs $16. If you buy four of them, then you paid 4*16 = 64 dollars.

The total bill was $96.50

This leaves 96.50-64 = 32.50 for parking.

======================================================

Part (b)

Answer:  y = 16x+32.50

--------------------

Work Shown:

x = number of tickets

y = total bill (in dollars)

1 ticket costs 16 dollars

x tickets cost 16x dollars since we multiply both values by x

Add on the cost of parking to get a total bill of y = 16x+32.50

======================================================

Part (c)

Answer:  at most 13 tickets

In other words, 13 is the max you can get.

--------------------

Work Shown:

Plug y = 250 into the equation found back in part (b). Solve for x

We'll follow PEMDAS in reverse to isolate x

y = 16x+32.50

250 = 16x+32.50

16x+32.50 = 250

16x = 250-32.50

16x = 217.5

x = 217.5/16

x = 13.59375

Since we can't buy a fraction of a ticket, we must round down to the nearest whole number. We cannot round to x = 14 despite the value 13.59375 being closer to 14 as it is to 13.

x = 13 is the answer we're after.

If we plug in x = 13, we get

y = 16x+32.50 = 16*13+32.50 = 240.5

while x = 14 leads to

y = 16x+32.50 = 16*14+32.50 = 256.5

The first result of $240.50 is under $250 while the second result $256.50 is over $250. So that's why x = 13 is the largest number of tickets we can buy.

a) The parking fee is $32.50.

b) The equation is T(N) = 16N + Parking fee

c) Approximately 13 or 14 tickets.

We have,

a)

Total bill - Cost of tickets = Parking fee

$96.50 - ($16 * 4) = Parking fee

$96.50 - $64 = Parking fee

Parking fee = $32.50

b)

Total bill = T

Number of tickets = N

The equation that gives your total bill (in dollars) as a function of the number of tickets you buy is:

T(N) = 16N + Parking fee

c)

T(N) = 16N + Parking fee

Substituting the given values:

$250 = 16N + Parking fee

$250 = 16N + $32.50

$250 - $32.50 = 16N

$217.5/16 = N

N ≈ $13.6

Thus,

a) $32.50

b) T(N) = 16N + Parking fee

c) Approximately 13 or 14 tickets.

Answers

Answer:

120

Step-by-step explanation:

There are 120 ways can eight letters be arranged into groups of five where order matters and the first two letters are already chosen.

What is Combination?

A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Since, we're dealing with a problem where the order matters and the first two letters are already chosen we need to subtract the number of letters and the number of available slots per group.

Here, We use the permutation formula to find the answer, but before that let's check values.

n = 8

k = 5

Now since there are two letters already chosen we have to deduct two from both the value of n and k.

n = 6

k = 3

Hence, we can use the permutation formula:

P (n, k) = n! / (n - k)!

P (6, 3) = 6! / (6 - 3)!

P (6, 3) = 120

Thus, There are 120 ways can eight letters be arranged into groups of five where order matters and the first two letters are already chosen

Solve for x in the triangle. You must show your starting equation and all work. Then calculate the value of each angle in the triangle.

Answers

Answer: x = 59

Step-by-step explanation:

A triangle all adds up to 180°.
Therefore you must add them all up and equal them to 180.


Shown below:

2x+1+3x+x+5=180

Then of course you have to solve it.

Shown below:

6x+6=180

Move the 6 over to the side of 180 which leaves 6x by itself.

Shown below:

6x=180-6

Then solve the equation:

6x=174

Solve x:

x= 174/6

Hence, leaving x as 29°

After finding x, you must substitute it in the x values. Hope this was helpful.

What is Pythagoras theorem?

The Pythagoras theorem states that if a triangle is right-angled, then the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Formula of Pythagoras theorem

Hypotenuse² = Perpendicular² + Base²

According to the question

A plane flies 35 km in the direction N 30° W,

and then flies 60 km in the direction N 60° E

i.e

When we plot its figure

we will observe it will form a right angled triangle

with perpendicular = 35 km ,  Base = 60 km

and Hypotenuse = distance form original location to current location

Now,

By using the formula of Pythagoras theorem

Hypotenuse² = Perpendicular² + Base²

Hypotenuse²  = 35² + 60²

Hypotenuse² = 4825

Hypotenuse = 69.46 km

Hence, the distance of the plane from its original location is 69.46 km.

A van travels 180 miles on 12 gallons of gas. At that rate, how much gas will it need to travel 330 miles

Answers

Answer: 22 gallons of gas.

The amount of gas needed to travel 330 miles will be 36.67 gallons.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The rate is the ratio of the amount of something to the unit.

For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

A van travels 180 miles on 12 gallons of gas. Then the rate is given as,

Rate = 20 / 180

Rate = 0.1111 gallons per mile

At that rate, the amount of gas needed to travel 330 miles will be given as,

⇒ 330 x 0.1111

⇒ 36.67 gallons

The amount of gas needed to travel 330 miles will be 36.67 gallons.
