I need help please with this equation:

Answer:

20/3

Step-by-step explanation:

8 times 3 plus 2 is 20. So 20/3

Answer:

1) The conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].

2) -111

3) It is because number and its conjugate have the same numbers but their second components are opposite to each other.

Step-by-step explanation:

1) A radical number of the form [tex]r = a + b\sqrt{c}[/tex], [tex]\forall \,a,b,c\in \mathbb{R}[/tex], where the first component is a non-radical real number which acts as a "pivot" and the second component is the radical component, which generates a "displacement" from pivot.

The conjugate of [tex]r[/tex] is a real number [tex]s = a - b\sqrt{c}[/tex],  [tex]\forall \,a,b,c\in \mathbb{R}[/tex], which that is "pivot" plus "displacement" in the direction opposite to that of [tex]r[/tex]. We proceed to complement this explanation with the image attached below.

Then, the conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].

2) We proceed to performed all the need algebraic operation until result is found:

1) [tex](6+7\sqrt{3})\cdot (6-7\sqrt{3})[/tex] Given

2) [tex]6\cdot (6-7\sqrt{3})+7\sqrt{3}\cdot (6-7\sqrt{3})[/tex] Distributive property

3) [tex]6\cdot [6+(-7)\cdot \sqrt{3}]+7\cdot \sqrt{3}\cdot [6+(-7)\cdot \sqrt{3}][/tex] Definition of subtraction/ [tex]-a\cdot b = (-a)\cdot b[/tex]

4) [tex]6\cdot 6 +[6\cdot (-7)]\cdot \sqrt{3}+(6\cdot 7)\cdot \sqrt{3}+[7\cdot (-7)]\cdot (\sqrt{3}\cdot \sqrt{3})[/tex] Distributive, associative and commutative properties

5) [tex]36 +(-42)\cdot \sqrt{3}+42\cdot \sqrt{3}+(-49)\cdot 3[/tex] Definition of multiplication/[tex]-a\cdot b = (-a)\cdot b[/tex]/Definition of square root

6) [tex][36 +(-147)]+\sqrt{3}\cdot [42+(-42)][/tex] Commutative, associative and distributive properties/[tex]-a\cdot b = (-a)\cdot b[/tex]

7) [tex]-111+\sqrt{3}\cdot 0[/tex] Definition of subtraction/Existence of additive inverse

8) [tex]-111+0[/tex] [tex]a\cdot 0 = 0[/tex]

9) [tex]-111[/tex] Modulative property/Result

3) It is because number and its conjugate have the same numbers but their second components are opposite to each other.

Given :

Jaylen earns the same amount of money each month.

His telephone bill is 1/20 of his monthly earnings, and he pays a total of $840 each year for his telephone service.

To Find :

How much does Jaylen earn each month, in dollars.

Solution :

Monthly payment of telephone bill is :

[tex]M = \$ \dfrac{840}{12}\\\\M = \$70[/tex]

Let, his monthly salary is A.

So,

[tex]M = \dfrac{A}{20}\\\\A = 20\times M\\\\A = 20 \times 70\\\\A = \$1400[/tex]

Therefore, Jaylen monthly income is $1400.

Answer:

1/10

Step-by-step explanation:

you can find the reciprocal of 2 (which is 1/2) and multiply it to 1/5 and get 1/10, that is your answer

I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!

Answer:

1/10

Step-by-step explanation:

You first divide and then divide just becomes multiplication(I know its weird)

K(Keep)         C(Change)                              F(Flip)

(1/5 )     (division becomes) x     (The whole number 2 becomes the recipicol  1/2)

Then you multiply 1/5 times 1/2 =1/10

Answer:

x=-1

Step-by-step explanation:

10+3x=5-2x     (Add 2x to both sides)

10+5x=5          (Subtract 10 from both sides)

5x=-5               (Divide both side by 5)

x=-1

Answer:

x=-1

Step-by-step explanation:

10 + 3x= 5 – 2x

You first +2x on both sides

10 + 3x+2x= 5 – 2x+2x

subtract 10 on both sides

10-10+5x=5-10

Then divide 5 to isolate x

5 divide 5x=-5 divide 5

x=-1

Hope that helps :)

Step-by-step explanation:

6 tenths and 00.6

Answer:

-30

Step-by-step explanation:

Substituting values of a and b in equation

3(-5)+2(-6)-3

-15-12-3

-15-15

-30

Answer: -30.

Step-by-step explanation:

We start by multiplying 3 by -5 and 2 by -6.

So the new equation will be [tex]-15-12-3[/tex].

Then, we can either minus -12 by -3 or we can minus -15 by -12. Either way, we get the right answer.

[tex]-15-12=-27[/tex]

Then, the new equation will be [tex]-27-3[/tex].

[tex]-27-3 = -30[/tex].

Answer: [tex]-30[/tex].

Answer:

5z^2-8z+3

-5×-3=15

-5+-3=-8

so...

5z^2-5z-3z+3

5z(z-1)-3(z-1)

therefore the answer is...

(5z-3) (z-1)

Answer:5a+13

Step-by-step explanation:3a +7 +6+2a

                                             = 3a +2a +7 +6

                                               =5a+13

Combine the like terms.

Answer:

Y = 8

Step-by-step explanation:

7- -1 is 8. If you're subtracting a negative, you're basically adding.

So 7+1 is 8.

Answer:

y = 9

Step-by-step explanation:

Trying to get the variable alone is the main goal in solving these

to get the variable alone here we can divide both sides by 5, which gets us

y - 10 = -1

now we can add 10 to both sides to get  y = 9

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 1) ← 2 points on the line

m = [tex]\frac{1-0}{0-(-2)}[/tex] = [tex]\frac{1}{0+2}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

0.1728

Step-by-step explanation:

6^-2= 1/6^2

3^-3= 1/3^3

1/36 * 1/27 * 3.6 * 3.6 * 3.6

= 0.1728

Answer:

x = -1

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    4/12-((x+2)/(2*x+5))=0

                    x + 2

Simplify   ——————

                    2x + 5        

                           1

Simplify again   —

                           3

1       (x + 2)

— - —————  = 0  

3       2x + 5

Find the Least Common Multiple

     The left denominator is :       3  

     The right denominator is :       2x+5  

       Number of times each prime factor

       appears in the factorization of:

Prime  

Factor   Left  

Denominator   Right  

Denominator   L.C.M = Max

{Left , Right}  

3 1 0 1

Product of all  

Prime Factors  3 1 3

                 Number of times each Algebraic Factor

           appears in the factorization of:

   Algebraic    

   Factor      Left  

Denominator   Right  

Denominator   L.C.M = Max  

{Left , Right}  

2x+5  0 1 1

     Least Common Multiple:

     3 • (2x+5)  

Denote the Least Common Multiple by  L.C.M  

Denote the Left Multiplier by  Left_M  

Denote the Right Multiplier by  Right_M  

Denote the Left Deniminator by  L_Deno  

Denote the Right Multiplier by  R_Deno  

Left_M = L.C.M / L_Deno = 2x+5

Right_M = L.C.M / R_Deno = 3

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.                     2x+5    

  ——————————  =   ——————————

        L.C.M                               3 • (2x+5)

  R. Mult. • R. Num.                (x+2) • 3

  ——————————  =   ——————————

        L.C.M                            3 • (2x+5)

Add the two equivalent fractions which now have a common denominator . Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2x + 5 - ((x + 2) • 3)                  -x - 1    

———————————  =  —————————

       3 • (2x + 5)                     3 • (2x + 5)

Pull out like factors :

  -x - 1  =   -1 • (x + 1)  

            -x - 1    

 —————————— = 0  

         3 • (2x + 5)

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now, to get rid of the denominator, multiply both sides of the equation by the denominator.

        -x - 1  

 ——————— • 3 • (2x + 5) = 0 • 3 • (2x + 5)

   3 • (2x + 5)

Now, on the left hand side, the  3 • 2x + 5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -x - 1  = 0

Solving a Single Variable Equation:

Solve  :    -x - 1 = 0  

Add  1  to both sides of the equation :  

                     -x = 1

Multiply both sides of the equation by (-1) :  x = -1

Answer:

156 cm²

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = Ah ( A is the area of the base and h the height )

Here V = 936 and h = 6, then

936 = 6A ( divide both sides by 6 )

A = 156 cm²
