7x+15=4x+66
solve for x.

Answers

Answer 1

Answer: x=17

Step-by-step explanation:

7x + 15 = 4x + 66    Subtract 4x from both sides

-4x         -4x

3x + 15 = 66    subtract 15 from both sides

      -15     -15

3x =  51   Divide both sides by 3

x= 17

As part of a social experiment, Joey sent an email to 2 friends. The email asks the person reading it to forward it to 3 people. The table shows the distribution of the email, assuming that everyone who recelves the email forwards it to 3 new people. Number of iterations Number of People Recelving the Email.​

Answers

Answer:

I can not see the table, so i will answer this in a general way.

Ok, let's see a rough image of what is happening.

First, Joey sends the email to 2 friends.

So first, 2 people have the email

Then each friend sends the email to 3 new people.

So now the number of people that has the email is:

2 + 2*3 = 2 + 6.

Now, the 6 new people that received the email send it to other 3 new people each, so now the number of people that got the email is:

2 + 6 + 6*3

and so on.

We already can see the pattern here, we can write this as:

∑aₙ

Where aₙ = 3*aₙ₋₁

and a₀ = 2.

So with that information, we can find the number of iterations, n, for a given number of people that received the email A.

A = ∑aₙ = (a₀ + a₁ + a₂ + ....) = (2 + 2*3 + 2*3*3 + ...)

Step-by-step explanation:

A bucket is filled with water up to the 4 gallon mark. The bucket springs a leak and water begins draining at a constant rate of 5/19 gallons per minute. Write a formula to determine the number of gallons of water n in the bucket in terms of the number of minutes t the water has been draining

Answers

Answer:

n = 4 - [tex]\frac{5}{19}[/tex]t

Step-by-step explanation:

n determines the amount of water in the bucket, it's basically the total, so that's why it's there. 4 is the number of gallons of water that you started with and 5/19 is the number of gallons that are draining per minute.  t is the amount of time or minutes that have gone by. So, that's why the equation is   n = 4 -[tex]\frac{5}{19}[/tex]t

HELP. LOOK AT THE PICTURE

Answers

Answer:

B

Step-by-step explanation:

Since the person used >200 kWh that month, you would use the bottom equation: 0.15(x-200)+20.

(BTW, the x>200 or x≤200 means if they used more or less than/equal to 200 hours)

From there, you can plug in the number of hours for x, which is 400. So, 0.15([400]-200)+20

0.15(200)+20

30+20

50

The bill for a person that uses 400 KWh is $50.

Option B is the correct answer.

We have,

The number of kilowatts is more than 200.

So,

From the piecewise function choose the function for x > 200.

i.e

b(x) = 0.15 (x - 200) + 20

This is used to calculate the bill.

Now,

Substitute x = 400 KWh in b(x).

b(x) = 0.15 (x - 200) + 20

Simplify the expression.

= 0.15 (400 - 200) + 20

= 0.15 x 200 + 20

= 30 + 20

Add the values.

= 50

Thus,

The bill for a person that uses 400 KWh is $50.

Carlos is building a game room adjacent to his living room so that both rooms will have the same width. he created the model shown below. (x+4) (2x+6) (x-4)Part A: write an expression for the total area of both rooms Part B: if the length of the game room is 12 feet, what is the total square footage of the two rooms??

Answers

Answer:

1,000 sq ft

Step-by-step explanation:

Part A:

To find the total area of both rooms (length x width):

(x+4)(2x+6+x-4)

(x+4)(2x+2+x)

2x²+2x+x²+8x+8+4x

= 3x²+14x+8

Part B:

If the length of the game room = 12 ft, we can solve for x:

Game room = (x-4)=12; therefore x=16

Plug 16 in for x in the equation from Part A:

3x²+14x+8 becomes 3(16)²+14(16)+8

= 1,000 sq ft

Answers

Answer:

the number of boxes that would take fill

the storage completely is 60 boxes.

Step-by-step explanation:

given:

A storage unit has the dimensions 6 ft. x 7 1/2 ft. x 4 1/2 ft.

find:

What number of

1 1/2 ft. x 1 1/2 ft. x 1 1/2 ft. cardboard boxes would it take to completely

fill this storage unit?

Volume of a storage unit = 6 x 7.5 x 4.5

Volume of a storage unit = 202.5  ft³

Volume of a cardboard box = 1.5 x 1.5 x 1.5

Volume of a cardboard box = 3.38 ft³

to get the number of cardboard boxes to fill in the storage unit,

Number of boxes =     202.5 ft³    

                                     3.38 ft³

Number of boxes = 60

therefore,

the number of boxes that would take fill the storage completely is 60 boxes.

A store sells bouquets of fruits for $10 a bouquet. The daily cost to produce x bouquets of fruits is defined by the function f(x) = – x 4 + 3x 3 + 5x 2 + 20x + 1.

Answers

Answer:

5 or C

Step-by-step explanation:

when you plug in 5, you get -24 as the cost. Then you take that number with the amount of money you make selling 5 flowers and that would be $50 since they are $10/per bouquet. Then when you subtract you get a positive profit of $26.

Answer:

5

Step-by-step explanation:

For profit to be had, the selling price (represented by $10x, x being number of bouquets sold) must be greater than the cost to produce (here, -x^4 + 3x^3 + 5x^2 + 20x +1).

Set up an inequality such that 10x is greater than the cost to produce.

10x > -x^4 + 3x^3 + 5x^2 + 20x + 1

-Solving the inequality by subtracting 10x from both sides, we have:

0 > -x^4 + 3x^3 + 5x^2 + 10x + 1

-Using a graphing calculator, (the one they give you on Edgenuity) graph the new function and look for where the graph is below the x axis. (y is less than 0)

Looking at the graph, we see that when x is greater than 0, (you can't sell a negative amount of bouquets) y is greater than 0 up until x = 4.579. After 4.579, the y values become negative. (what we want to be looking at according to the inequality.)

You can't sell 4.579 bouquets, and even if you could, you'd be breaking even, with y=0. The answer isn't 4, because according to the graph and inequality, y would be greater than 0 (making the inequality false). Because of this, we have to find the next whole positive number that would make the inequality true, and that is 5.
