Hello guys I just wanted to know the answer or this problem, Meredith rented a bike from Bubba's Bike Shack. They charged $2 per hour. Meredith paid $26. Which equation could be used to find h, the number of hours Meredith rented the bike? Thanks for reading, and help me please

Answers

Since they charge $2 per hour, 2 is the variable, and x is the number of hours.

To find the number of hours after paying 26 dollars:
2x = 26

To solve for x: Divide both sides by 2
2x/2 = 26/2
1x = 13

Answers

Answer:

h = (3 - x)/2

Your answer is not correct.

Step-by-step explanation:

⅓(x + 2h) + 1 = 2

Subtract 1 from both sides;

⅓(x + 2h) + 1 - 1 = 2 - 1

This gives;

⅓(x + 2h) = 1

Multiply both sides by 3;

⅓(x + 2h) × 3 = 1 × 3

This gives;

x + 2h = 3

Subtract x from both sides to get;

2h = 3 - x

Divide both sides by 2 to get;

h = (3 - x)/2

Can someone help?

Answers

Answer:

[tex](x,y) = (65^\circ, 50^\circ)[/tex]

Step-by-step explanation:

Let all values denote degrees.

By the exterior angle theorem, [tex]x + y = 115[/tex]. Moreover, because we are dealing with an isoceles triangle, [tex]y = 180 - 2x[/tex]. Substituting this into the former equation gives [tex]180-x=115[/tex] and as such [tex]x=65[/tex]. Because [tex]x + y = 115[/tex] we now also know that [tex]y=50[/tex].

Answer:

x° = 65° & y° = 50°.

Step-by-step explanation:

115° = x° + y° ( exterior angle property )

Let's name that angle to the right of 115° as 'a'.

a = 180 - 115 = 65°. (linear pair)

Now we know that the triangle is an isosceles triangle. (given)

So this makes x° also as 65° (equal sides make equal angles).

This leaves behind y°.

y° = 180 - (65+65) = 50°.

So, x° = 65° & y° = 50°.

* HELP* A book sold 39,900 copies in its first month of release. Suppose this represents 8.2% of the number of copies sold to date. How many copies have been sold to date? Round your answer to the nearest whole number

Answers

Answer:

Total copies sold= 486,585

Step-by-step explanation:

Giving the following information:

Number of copies sold in the first month= 39,900

% of copies sold in the first month= 8.2%

To calculate the total number of copies sold, we need to use the following formula:

Total copies sold= Number of copies sold in the first month/% of copies sold in the first month

Total copies sold= 39,900 / 0.082

Total copies sold= 486,585

Point B is the midpoint of AC, and point C is the midpoint of AD. If CD=12, what is AB?

Answers

Answer: AB = 6

Step-by-step explanation:

If CD = 12 , AC also = 12

B is the midpoint of AC so one side = 6

AB is one side of AC , so AB = 6

I am not a professional, I am simply using prior knowledge!

Note- It would mean the world to me if you would mark me brainliest!

The Distance between AB will be 12 units

ConceptFirst we will find the distance between point A and CAfter that we will divide the distance between A and C by 2 to find AB

What are steps to solve this problem?

The steps are as follow:

Distance between CD is given which is 12 unit To find AC we will double the distance between CD because C is midpoint of ADSo distance AC is given by:

AC = 2 x CD = 2 x 12 = 24 units

To find AB we will divide the AC by 2 because B is midpoint of ACSo distance AB is given by:

AB = AC/2

AB = 24/2 = 12 units

So Distance between points AB will be 12 units

The Taylors have a square rug in their living room that is "x" feet long on each side. The room is 3

feet wider and 5 feet longer than the rug. Write an expression to describe the perimeter of

the living room.

Answers

Answer:

[tex]Perimeter = 4x+16[/tex]

Step-by-step explanation:

Given

[tex]Rug=x[/tex]

Required

Determine the perimeter of the room

The room is 3ft wider.

So:

[tex]Width = Rug + 3[/tex]

[tex]Width = x + 3[/tex]

The room is 5ft longer,

So:

[tex]Length = Rug + 5[/tex]

[tex]Length = x + 5[/tex]

The perimeter is:

Expand: -1/3(-2x-21)

Answers

Answer:

Step-by-step explanation:

Simplifying

3(2x + -1) = 21

Reorder the terms:

3(-1 + 2x) = 21

(-1 * 3 + 2x * 3) = 21

(-3 + 6x) = 21

Solving

-3 + 6x = 21

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + 6x = 21 + 3

Combine like terms: -3 + 3 = 0

0 + 6x = 21 + 3

6x = 21 + 3

Combine like terms: 21 + 3 = 24

6x = 24

Divide each side by '6'.

x = 4

Simplifying

x = 4

Which is better to buy, 6 CD's for $12 or 8 CD's for $14.50?

Answers

Answer:

8 CDs for $14.50

Step-by-step explanation:

We have to divide both of the numbers by the number of CDs. Our formula is:

(price) ÷ (number of CDs) = price per CD

When we divide both of the prices by the number of CDs, we see that 6 CDs for 12.00 is worse because it is 2.00, whereas the inflation is lower when you compare to the other rate. You get $1.81.

Only 30 of Jahanna's 40 customers receive the newspaper on Sunday's. If it takes her 50 minutes to deliver to 40 customers on other days, how long will it take her to deliver the paper to 30 customers?

Answers

Answer: 37.5 minutes

Step-by-step explanation:

It takes Jahanna 50 minutes to deliver to 40 customers.

On Sunday however, she has to deliver to only 30 customers.

Assume that the amount of time it will take her is x minutes and use direct proportion:

50 minutes          :       40 customers

x minutes             :       30 customers

Cross multiply:

40x = 50 * 30

40x = 1,500

x = 1,500/40
