You want to paint a piece of pottery at an art studio. The total cost is the cost of the piece plus an hourly studio fee. There are two studios to choose from. For studio a: The vase is $10 and the studio fee is $8 per hour. For studio b: The vase is $16 and the studio fee is $6 per hour. After how many hours of painting are the total costs the same at both studios?

Answers

Answer:
3 hours

Explanation:
1) Set an expression for each of the studios we can set out variable as h for hours because that is the unknown value.

Studio A: 10+8h
Studio B: 16+6h

To find out how many hours would pass for their costs to equal each other, we have to make them literally equal each other.

10+8h=16+6h

Now that we have an equation, we can start solving.

10+8h=16+6h
Combine like terms
10-16=6h-8h
-6=-2h
2h=6
Divide both sides by 2 to isolate h
2h/2=6/2
h=3

Point V is on line segment \overline{UW}

UW

. Given UV=6,UV=6, UW=5x,UW=5x, and VW=4x-1,VW=4x−1, determine the numerical length of \overline{VW}.

VW

.

Answers

Answer: VW = 19

Step-by-step explanation: The segment UW has a point V between them, so:

UV + VW = UW

6 + 4x - 1 = 5x

4x + 5 = 5x

x = 5

The numerical length is

VW = 4x - 1

VW = 4(5) - 1

VW = 19

The measure, numerically, of VW is 19

You are signing up for a new gym on New Year's Day. Two gyms memberships have different payment plans. Gym A has a $60 signup fee and a monthly fee of $10. Gym B has a signup fee of $20 and a monthly fee of $15. At which month would the membership costs be the same?

Answers

Answer: August or the 8th month

Step-by-step explanation:

Assuming the month that the costs will be the same is x.

Gym A cost function will be = 60 + 10x

Gym B cost function will be =  20 + 15x

The formula will therefore be;

60 + 10x = 20 + 15x

60 - 20 = 15x - 10x

40 = 5x

x = 8

8th month is August.

4.5(3s+6)=?​

Answers

Answer:

13.5s + 27

Step-by-step explanation:

4.5(3s + 6)

We can use the distributive property:

4.5(3) s + 4.5(6) = 13.5s + 27

What is x in this equation? -2x - 4 + 5x =8

Answers

The answer is X=4! Hope this helped :)
X = 4

-2x - 4 + 5x = 8

Add up the X’s: 3x - 4 = 8

Isolate the X’s, Transfer -4 to the other side of the equal sign, while also flipping the sign (negative & positive): 3x = 8 + 4

Add up the 8 & 4: 3x = 12

Divide each side by 3: 3x/3 = 12/3

Final Answer: x = 4

what is 37.0691 rounded to the nearest tenth and thousandth ​

Answers

Answer:

Step-by-step explanation:

37.0691

To round to the nearest tenth you need to look 1 decimal place to the right of the tenths place which in this case is the 6

5 or more raise the score - 4 or less let it rest

so it would be 37.1 (tenths)

To round to the nearest thousandth you need to look 1 decimal place to the right of the thousandths place which in this case is the 1

5 or more raise the score - 4 or less let it rest

so it would be 37.069 (thousandth)

Avery is renting a car and needs to compare the prices of two car rental companies. Hertz charges $42 per day and an additional $32 in service charges. Enterprise charges $46 per day and an additional #24 in service charges.

Part A: Write an equation to represent each company's total charges for renting a car for a certain number of days. For both equations (one for Hertz and one for Enterprise), define the variable used.

Part B: Which company charges more for renting a car for 6 days? Justify your answer.

Part C: How much money does Avery save by renting a car from Hertz instead of Enterprise for 4 days? Show your work or explain your answer.

Answers

Answer:

Step-by-step explanation:

Since Hertz charges $42 per day and an additional $32 in service charges.

Another rental company Enterprise charges $46 per day and additional of $24 in service charges.

A). Let the duration of car rental = x days

    Hertz will charge = 42x + 32

    Enterprise will charge = 46x + 24

B). For x = 6 days

    Amount charged by Hertz = 42(6) + 32

                                                 = $284

    Amount charged by Enterprise = 46(6) + 24

                                                         = $300

    Therefore, Enterprise will charge more.

C). For x = 4 days

    Amount charged by Hertz = 42(4) + 32

                                                 = $200

    Amount charged by Enterprise = 46(4) + 24

                                                         = $208

    Savings from renting a car from Hertz = $208 - $200

                                                                    = $8
