Gasoline at a particular gas station cost $2.78 per gallon if Cory buys $18 of gas how many gallons did he buy?

Answer:

5a = 10a -6

Step-by-step explanation:

let the number be a.

so five times will be = 5a.....1)

and 6 less than 10times = 10a - 6......2)

since these numbers are same..

from 1) and 2)

5a = 10a -6

we can further simplify it ..

Answer:4/3x–12.

Step-by-step explanation: I just did this on khan and got it wrong but I used hints to get the answer, so here you go.

[tex]x^3=\boxed{x}\cdot x^2[/tex], and

[tex]\boxed{x}(x^2+2x+1)=x^3+2x^2+x[/tex]

Subtract this from [tex]x^3[/tex] to get a remainder of

[tex]x^3-(x^3+2x^2+x)=-2x^2-x[/tex]

[tex]-2x^2=\boxed{-2}\cdot x^2[/tex], and

[tex]\boxed{-2}(x^2+2x+1)=-2x^2-4x-2[/tex]

Subtract this from the previous remainder to get a new remainder of

[tex](-2x^2-x)-(-2x^2-4x-2)=3x+2[/tex]

[tex]3x[/tex] does not divide [tex]x^2[/tex], so we stop here.

What we've done is to write

[tex]\dfrac{x^3}{x^2+2x+1}=x-\dfrac{2x^2+x}{x^2+2x+1}[/tex]

then

[tex]\dfrac{x^3}{x^2+2x+1}=x-2+\dfrac{3x+2}{x^2+2x+1}[/tex]

and we stop here because the remainder term [tex](3x+2)[/tex] has a degree less than the degree of the denominator.

Alternatively, we can be a bit tricky and notice that

[tex]x^2+2x+1=(x+1)^2[/tex]

Now,

[tex](x+1)^3=x^3+3x^2+3x+1[/tex]

so that

[tex]\dfrac{x^3}{(x+1)^2}=\dfrac{(x+1)^3-(3x^2+3x+1)}{(x+1)^2}[/tex]

We can divide the first term by [tex](x+1)^2[/tex] easily to get

[tex]\dfrac{x^3}{(x+1)^2}=x+1-\dfrac{3x^2+3x+1}{(x+1)^2}[/tex]

Next,

[tex](x+1)^2=x^2+2x+1[/tex]

so that

[tex]\dfrac{x^3}{(x+1)^2}=x+1-\dfrac{3((x+1)^2-(2x+1))}{(x+1)^2}-\dfrac{3x+1}{(x+1)^2}[/tex]

[tex]\dfrac{x^3}{(x+1)^2}=x+1-3+\dfrac{6x+3}{(x+1)^2}-\dfrac{3x+1}{(x+1)^2}[/tex]

[tex]\dfrac{x^3}{(x+1)^2}=x-2+\dfrac{3x+2}{(x+1)^2}[/tex]

which is the same result as before.

Answer:

Approximately 45,455 total employees.

Step-by-step explanation:

So the company has 13,500 employees in one country. And this represents 29.7% of the company's employees.

In other words:

[tex]\frac{13,500}{\text{Total}}=0.297[/tex]

The left represents the number of employees in one country over the total number.

And the right is the decimal form of 29.7%. Simply move the decimal two places to the left and remove the percent symbol.

So, to solve for the total, multiply both sides by it first. The left side cancels:

[tex]\text{Total}(\frac{13500}{\text{Total}} )=\text{Total}(0.297)\\13500=\text{Total}(0.297)[/tex]

Now, divide both sides by 0.297. The right side cancels:

[tex]\text{Total}=\frac{13500}{0.297}[/tex]

Use a calculator.

[tex]\text{Total}\approx45454.5455[/tex]

So, there is approximately 45,455 total employees.

Answer:

[tex]\Large \boxed{\mathrm{45455 \ employees }}[/tex]

Step-by-step explanation:

29.7% of the company’s employees is 13,500.

Let the number of the company’s employees be x.

[tex]29.7\% \cdot x = 13500[/tex]

[tex]0.297x=13500[/tex]

Dividing both sides by 0.297.

[tex]x= 45454.5454545...[/tex]

There are 45455 employees in total (rounded to nearest whole number).

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

That's

Slope of the through points

(15, -6) and (-3, 13) is

Since the lines are parallel their slope are also the same

So slope of parallel line = - 19/18

Equation of the line using point (4,2) and slope -19/18 is

We have the final answer as

Hope this helps you

Answer:y=-1.583x-8.332

Step-by-step explanation:

First find slope from two points (-6-13)/(15+3)=-1.583

Now line is parallel so the slope would be same for the other line passing through (4,2) now as the general equation of line is

y=mx+c

2=-1.583(4)+c

Solving for c equals to -8.332

So final equation is

y=1.583x-8.332

Answer:

The answer is

Step-by-step explanation:

To find the inverse of f(x) equate f(x) to y

That's

y = f(x)

y = x - 2

Next interchange the terms.

That's x becomes y and y becomes x

We have

x = y - 2

Make y the subject

Send 2 to the left side of the equation

y = x + 2

We have the final answer as

Answer:  The fraction [tex]\frac{7}{17}[/tex]

This can be written as 7/17 if you are using a computer keyboard.

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

Explanation:

The two negatives next to each other basically cancel each other out to form a positive or a plus sign

We have

[tex]-\frac{9}{85} - \left(-\frac{44}{85}\right)[/tex]

turn into

[tex]-\frac{9}{85} +\frac{44}{85}[/tex]

From here, we add the fractions. To do this, we add the numerators and place the sum over the common denominator 85. This is only possible since both denominators are the same number.

[tex]-\frac{9}{85} +\frac{44}{85} = \frac{-9+44}{85} = \frac{35}{85}[/tex]

The last thing to do is to reduce this fraction as much as possible.

We see that 35 and 85 have 5 as a common factor. Divide each number by 5 to get...

Therefore, [tex]\frac{35}{85} = \frac{7}{17}[/tex]

So overall,

[tex]-\frac{9}{85} - \left(-\frac{44}{85}\right) = \frac{7}{17}[/tex]

Answer:

  12, 19, 26

Step-by-step explanation:

Each new term in the sequence is found by subtracting 7 from the previous term. So, each previous term can be found by adding 7 to the one you have.

The three previous terms (working backward) are ...

  5+7 = 12

  12+7 = 19

  19+7 = 26

Answer:

No

Step-by-step explanation:

What we have to do is find how much everything costs.

After we do that, we can compare that total cost with the amount she has to determine if she can afford everything.

Let's set up an expression to see how much everything costs.

2 Movie tickets: 7.25+7.25

Drink and Popcorn: 5.75

Total: 7.25+7.25+5.75

14.5+5.75

20.25

20.25>20

Therefore, they would not have enough money to purchase 2 tickets and drinks+popcorn.

Answer:

The solution to the given inequality is a > 8.

Step-by-step explanation:

For this problem, we have to solve for the inequality.

9a - 24 > 48

add 24 on both sides of the inequality.

9a > 72

Divide 9 on both sides of the inequality.

a > 8

So, your solution would be a > 8.

Answer:

a > 8

Step-by-step explanation:

To solve this inequality, we have to get the variable, a, by itself on one side of the equation

[tex]9a -24 > 48[/tex]

24 is being subtracted from 9a. The inverse of subtraction is addition. Add 24 to both sides of the equation.

[tex]9a-24+24 > 48+24[/tex]

[tex]9a > 48 +24[/tex]

[tex]9a > 72[/tex]

a is being multiplied by 9. The inverse of multiplication is division. Divide both sides of the equation by 9.

[tex]9a/9 > 72/9[/tex]

[tex]a > 72/9[/tex]

[tex]a > 8[/tex]

The solution to this inequality is a > 8

Answer:

False

Step-by-step explanation:

Step 1: Write out equation

-12 + n = -15

Step 2: Add 12 on both sides

n = -3

So our answer is -3 and not 3.

Answer: [tex]False[/tex]

The answer to this problem is [tex]n=-3[/tex]

To get -3 here is the work shown

Simplify both sides of the equation

[tex]n-12=-15[/tex]

Add 12 to both sides

[tex]n-12+12=-15+12\\n=-3[/tex]

The answer to this is Step 2: Distributive Property: a(b + 3) = ab + ac

Isaac's Steps are outlined below:

Step 1: (4.2) (-54) = (-54) (4.2)

Step 2: = (-5.4) (4) + (-5.4) (0.2)

Step 3: = (-21.6) + (-1.08)

Step 4: = 22.68

We observe that in Step 2:

(-5.4) (4.2) = (-5.4) (4 × 0.2) = (-5.4) (4) + (-5.4) (0.2)

Therefore, Isaac applied the distributive property in Step 2.

Answer:

mean 4.86

MAD = 1.91

Step-by-step explanation:

The required week that had greater variability in high temperature is week 2.

Given that,
The first week had a mean high temperature of 8 degrees Celsius and a mean absolute deviation (MAD) of 1 degree Celsius.
The second week had a mean high temperature of 4.86 degrees Celsius and a mean absolute deviation (MAD) of 1.91 degrees Celsius.

Statistics is the study of mathematics that deals with relations between comprehensive data.

Here,
The system of observation that has a higher mean absolute deviation, will have the chance of greater variability in high temperature. So,
mean absolute deviation of week 1 = 1
mean absolute deviation of week 2 = 1.91
MAD of week  2 > MAD of week 1

Thus, the required week that had greater variability in high temperature is week 2.

Diberikan sebagai berikut:

Jumlah maksimal toko sepatu yang bisa menampung = 400 pasang

Jumlah maksimal sepatu pria = 150 pasang

Jumlah terkecil sepatu wanita = 150 pasang

Keuntungan sepatu pria = Rp 1000

Keuntungan sepatu wanita = Rp. 500

Karena itu, jumlah maksimum sepatu wanita:

(Toko sepatu maksimum dapat menampung - jumlah maksimum sepatu pria)

(400 - 150) = 250 pasang

Keuntungan terbesar yang bisa dicapai:

(Jumlah sepatu pria * keuntungan) + (jumlah sepatu wanita * keuntungan)

(150 * 1000) + (250 * 500)

Rp. 150.000 + Rp. 125.000
