9c + 6 = 24 what does the variable c equal

Answers

Answer:

c = 2

Step-by-step explanation:

Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 6 from both sides of the equation:

9c + 6 (-6) = 24 (-6)

9c = 24 - 6

9c = 18

Next, divide 9 from both sides of the equation:

(9c)/9 = (18)/9

c = 18/9

c = 2

c = 2 is your answer.

[tex]{\boxed{\tt{c = 2}}}[/tex]

Step-by-step explanation:

Concept :

Here, we will use the below following steps to find a solution using the transposition method:

Step 1 :- we will Identify the variables and constants in the given simple equation.Step 2 :- then we Simplify the equation in LHS and RHS.Step 3 :- Transpose or shift the term on the other side to solve the equation further simplest.Step 4 :- Simplify the equation using arithmetic operation as required that is mentioned in rule 1 or rule 2 of linear equations.Step 5 :- Then the result will be the solution for the given linear equation.

[tex]\begin{gathered}\end{gathered}[/tex]

Solution :

[tex]\implies{\tt{9c + 6 = 24}}[/tex]

[tex]\implies{\tt{9c = 24 - 6}}[/tex]

[tex]\implies{\tt{9c = 18}}[/tex]

[tex]\implies{\tt{c = \dfrac{18}{9}}}[/tex]

A magic 8-ball has a diameter of 5 inches. It is filled 85% full with blue water. How much space is occupied by the water?

Answers

Answer:

42.7 in^3 of the interior space is occupied by blue water

Step-by-step explanation:

1.  Find the volume of the ball.

2. Take 85% of this volume.

Volume of a sphere:  V = (4/3)(pi)(radius)^3

Here this volume is V = (4/3)(3.14)(125 in^3), or 50.24 in^3

85% of this volume is 0.85(50.24 in^3) = 42.7 in^3

42.7 in^3 of the interior space is occupied by blue water.

Great Escape bought a vintage bicycle for $3,000. They marked it up
40% to sell in their store. Then, they ran a sale for 30% off. What
was the discount price of the bicycle?

Answers

Answer:

Solution,

CP of a bicycle=$3000

Marked up=40%

Now,  

→40% of $3000

→40/100x$3000

→$1200

→$3000+$1200=$4200

Again,

Discount(d)=30%

→30%of $4200

→30/100x$4200

→$1260

Hence, the discount price of the bicycle is $1260

Step-by-step explanation:

The discount price of the bicycle will be $1260.

What are profit and loss?

One of a company's financial accounts, an income statement or profit and loss account, lists the company's revenues and costs for a specific time period. It describes the process through which revenues are converted into net income or net profit.

Given that Great Escape bought a vintage bicycle for $3,000. They marked it up

The discounted price of the bicycle will be calculated as:-

Marked up=40%

40% of $3000

40/100x$3000

$1200

$3000+$1200=$4200

Now discount of 30%.

30%of $4200

30/100x$4200

$1260

Hence, the discount price of the bicycle is $1260.

Answer:

£120

Step-by-step explanation:

If the phone has been discounted by 35%, then it is now 65% of the original price (as 100 - 35 = 65).

Divide the discounted price by 65 to find the amount per 1%, then multiply by 100 to get the original price.

(78 ÷ 65) x 100 = £120

Answer:

It was about $222.86

Step-by-step explanation:

1.) First cross multiply [tex]\frac{78}{x}[/tex] x [tex]\frac{35}{100}[/tex]  (new price over original price) x (percent over 100)

2.) 78 x 100 is 7800 and 35 x (x) is just 35x

3.) 35x=7800; So divide by 35 on both sides

4.) You get X= 222.857143 so about $222.86 was the original price

Juan needs to earn $500 to buy a bike. He already has $200 in the bank. If he earns $9 per hour at his job. If
x represents hours, which inequality could you use to find at least how many hours he has to work to buy it?

Answers

Answer:

33.3

Step-by-step explanation:

First, let's figure out how much more Juan needs to buy a bike: 500-200=300. He earns 9/hr of work. We can now use this information to find the inequality: 300/9=33.3

So Juan needs to work 33.3 hours at least to earn enough money. So therefore he has to work 33.3 hours to earn $300.

Laura just finished a new book about a time-traveling magician. She read the same amount every day and completed the book in just 10 days! The book had 85 pages.How many pages did Laura read each day?

Answers

So you have 85 pages and 10 days.
You would do 85/10 to get 8.5 pages each day. Hope that’s right !

The number of pages read by Laura each day if The book had 85 pages, the same amount every day, and completed the book in just 10 days, is 8.5.

What is division?

When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

For instance, 4 2 = 2. As a multiplication fact, this can be expressed as 2 + 2 = 4.

Given:

The book had 85 pages, the same amount every day, and completed the book in just 10 days,

Calculate the number of pages read each day as shown below,

The number of pages read each day = total number of pages / total number of days

The number of pages read each day =85 / 10

The number of pages read each day = 8.5

Thus, The number of pages read each day is 8.5 pages per day.

Combine 1.5x and 3x to get 4.5x.

Add 7 to both sides.

4.5x = 20 + 7

Divide both sides by 4.5.

x = [tex]\frac{27}{4.5}[/tex]
