HELP ME!!! Why is it possible to isolate the variable, x, in the equation 2x = 20 by using either the division property of equality or the multiplication property of equality?​

Answer:

30

Step-by-step explanation:

2/3 = .6

18/.6 = 30

Answer:

27

Step-by-step explanation:

If you want to divide a fraction, you have to divide it from it's reciprocal.

The reciprocal of 2/3 is 3/2.

Now, you have to multiply 3 and 18

18 x 3/2 = 54/2

54 divided by 2 is 27.

Hope it helped :>

Answer:

[tex]\frac{941}{999}[/tex]

Step-by-step explanation:

Let x = 0.941941........

Three digits are repeating. So, multiply both side by 1000

1000x = 941.941941......       (I)

       x =      0.941941....... (II)  {subtract equation (II) from (I)  }

 999x = 941

x = 941/999

Answer:

[ (-1,0) (0,0) (1,1) (2,2) (3,3) ]

Domain = { -1,0,1,2,3 }; Range = { 0,1,2,3 }

Step-by-step explanation:

Set or collection of ordered pairs is called 'Relation'. The ordered pairs are in terms f x & y coordinate.

Eg : [ (-1,0) (0,0) (1,1) (2,2) (3,3) ]

Domain is a set of all x axis values. Range is a set of all y axis values. They are arranged non repetitively in ascending order.

Domain = { -1,0,1,2,3 }

Range = { 0,1,2,3 }

As mentioned : the relation has been designed, as such to have five elements in its domain and four elements in its range

Answer:

The difference quotient is 4.

Step-by-step explanation:

Given that:

[tex]g(x) = 4x - 1[/tex]

To find:

Difference quotient = ?

where [tex]h \neq 0[/tex]

Solution:

Formula for Difference quotient is given as:

[tex]\dfrac{g(x+h)-g(x)}{h}[/tex]

First of all, let us find out [tex]g(x+h)[/tex]

Replacing [tex]x[/tex] with [tex]x+h[/tex]

[tex]g(x+h) = 4(x+h)-1 \\\Rightarrow g(x+h) = 4x+4h-1[/tex]

Now,

[tex]g(x+h)-g(x) = (4x+4h-1 )-(4x-1)\\\Rightarrow g(x+h)-g(x) = 4x+4h-1 -4x+1\\\Rightarrow g(x+h)-g(x) = 4h[/tex]

Putting the above value in:

[tex]\dfrac{g(x+h)-g(x)}{h} = \dfrac{4h}{h}[/tex]

We are given that, [tex]h \neq 0[/tex]

[tex]\therefore \dfrac{4h}{h} = 4[/tex]

So, the difference quotient is 4.

Answer:

-4-6x

Step-by-step explanation:

you would just combine -2 and 3 so you get 1 and then you would get 1-(5-6x) and you can just take away the parenthesis since in this case it doesn't matter and when you simplify that you get -4-6x

Answer:

[tex]\Huge \boxed{\mathrm{12.67 \ s}}[/tex]

Step-by-step explanation:

[tex]\displaystyle power \ (W) = \frac{work \ done \ (J)}{time \ (s)}[/tex]

[tex]\displaystyle P= \frac{W}{t}[/tex]

[tex]\displaystyle 15= \frac{190}{t}[/tex]

Solve for t.

Multiply both sides by t.

[tex]15t =190[/tex]

Divide both sides by 15.

[tex]\displaystyle t= \frac{190}{15}[/tex]

[tex]t \approx 12.67[/tex]

[tex] \bf \underline{ \underline{given : }}[/tex]

[tex]\bf \underline{ \underline{To \: be \: calculated : }}[/tex]

Calculate the time ?

[tex]\bf \underline{ \underline{

Formula \: applied :}}[/tex]

[tex] \boxed{ \bf{Power = \frac{Work \: done}{Time} }}[/tex]

[tex]\bf \underline{ \underline{Solution : }}[/tex]

We know,

[tex]\sf {Power = \dfrac{Work \: done}{Time}}[/tex]

[tex] \sf{ Time = \dfrac{Work \: done}{Power } }[/tex]

Substituting the values of work and power, we get:

[tex] \sf \implies{Time = \dfrac{190}{15} }[/tex]

[tex] \sf\implies{Time = 12.66 \: s}[/tex]

Thus,the time taken by a body is 12.66 seconds.

Answer:

y=1.5x

Step-by-step explanation:

Step 1: State what you know

Pineapples are 1.50 per pound

X represents how many pounds of pineapples you want to buy

Y represents how much do 'x' amount of pineapples cost in dollars

Step 2: Write the equation

y (the price of 'x' pounds of pineapple)=1.5(the cost of a pineapple)x(how many pounds of pineapples you bought)

Therefore the equation that represents the problem is y=1.5x

Answer:

y=1.5x

Step-by-step explanation:

Answer:

$384

Step-by-step explanation:

Original price = $ 400

Increased price  = 20% of 400

                           = [tex]\frac{20}{100}[/tex] * 400

                           = $  80

Price after increase = 400 + 80 = $ 480

Decreased price  = 20% of 480

                             = [tex]\frac{20}{100}\\[/tex] * 480

                            = $ 96

Price after decreasing 20% = 480 - 96 = $ 384

Final price of the toy = $ 384

Answer:

x = 7, x = 2

Step-by-step explanation:

Given

x² = 9x - 14 ( subtract 9x - 14 from both sides )

x² - 9x + 14 = 0 ← in standard form

(x - 7)(x - 2) = 0 ← in factored form

Equate each factor to zero and splve for x

x - 7 = 0 ⇒ x = 7

x - 2 = 0 ⇒ x = 2

Answer: x = 15

Step-by-step explanation: Since x is multiplied by 3, divide both sides

of the equation by 3 to get x by itself, and show all your work!

Put both sides of the equation over 3

and cancel out the 3's on the left side.

It's tempting to want to show off your

math skills by doing the work in your head.

Don't fall into this trap!

It's extremely important to develop the habit

of writing every step down on paper or digitally.

It will serve you very well for many years.

Answer:

1/2(x+y) - 1/3

Step-by-step explanation:

I think this may be the answer based on the info you've given

Answer:

[tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex]

Step-by-step explanation:

We can translate these words into an expression by just reading them and interpreting them.

Half the sum of x and y.

We know that it's going to include [tex](x+y)[/tex], and if we're taking half of that, we multiply that by [tex]\frac{1}{2}[/tex], so [tex]\frac{1}{2}(x+y)[/tex]

We also know that one third of y will be multiplying y by [tex]\frac{1}{3}[/tex], so [tex]\frac{1}{3}y[/tex].

Since we are decreasing [tex]\frac{1}{2}(x+y)[/tex] by  [tex]\frac{1}{3}y[/tex], there's a minus sign between the terms.

So, [tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex].

Answer:

0

Step-by-step explanation:

So we have the equation:

[tex]3(x+14)=42[/tex]

Divide both sides by 3:

[tex]x+14=14[/tex]

Subtract 14:

[tex]x=0[/tex]

The value of x is 0

Answer: x=0

Step-by-step explanation:

Given

3(x+14)=42

Distributive property

3x+42=42

Subtract 42 from both sides

3x=0

Divide 3 on both sides

x=0

----------------------------------------------------

Given

3(x+14)=42

Divide 3 on both sides

x+14=14

Subtract 14 on both sides

x=0

Both ways are fine

Answer:

1500

Step-by-step explanation:

Step 1: Understand what the question is asking you

It wants to know how much cells do you start off with or in other words how much cells are in the culture when time is 0

Step 2: Set t = 0

[tex]N = 1500(2^{0.18(0)} )[/tex]

Step 3: Solve for N

[tex]N = 1500(2^{0.18(0)} )[/tex]

[tex]N = 1500(2^{0} )[/tex]

[tex]N = 1500(1 )[/tex]

[tex]N = 1500[/tex]

Therefore when the initial amount of cells there in the culture is 1500
