The solution of the given equation are;  X = -2 - 2√3 or x = -2 + 2 √3

An equation is an expression that shows the relationship between two or more numbers and variables.

We have been given an equation as 3/x-4 = x-5/x

Therefore, 3/x-4 = x-5/x

3 - 4x /x = x² - 5 / x

Cancel out the denominator;

3 - 4x =  x² - 5

x² - 5 - 3 + 4x = 0

x² - 8 + 4x = 0

x² + 4x - 8 = 0

For the value of x;

x = 4 + √16 + 32 / 2

x =  -2 + 2√3

OR

x = 4 - √16 + 32 / 2

x = -2 - 2√3

Hence, The solution of the given equation are;  X = -2 - 2√3 or x = -2 + 2 √3

Answer:

4 1/8 square feet

Step-by-step explanation:

Area= l*b assuming that it's a rectangle or a square

2 3/4* 1 1/2= to do this we need to convert these mixed fractions to improper fractions (How to convert-Multiply the whole number part by the fraction's denominator. Add that to the numerator. Then write the result on top of the denominator.)

so, 2 3/4 converted will be- 11/4

& 1 1/2 converted will be- 3/2

11/4*3/2=33/8

Now we need to convert this into a mixed fraction again, coz the question was given in that form. (How to convert-Multiply the whole number part by the fraction's denominator. Add that to the numerator Then write the result on top of the denominator.)- so,

The ans would be 4 1/8 sqft

Answer:

a(5)=-48

Step-by-step explanation:

I think u r confused

this sequence is geometric not arithmetic

HOw we know that ??

when we get a common difference  that must Be equal  

d=6+3=9  not equal to  d=-12-6=-18

So it is not arithmetic

but when we get the common ratio that also must be equal

r=6/-3=-12/6=24/-12=-2   equal

So it is geometric

By using this equation:

a(n)=a*r^(n-1)

and we have a=-3 , r=-2

Then       a(n)=-3*(-2)^(n-1)

To get the next term:

a(5)=-3*(-2)^(5-1)

a(5)=-3*(-2)^(4)

a(5)=-3*16=-48

Answer:

-5 (11t - 30)

Step-by-step explanation:

Rewrite 150 as 5 * 30

Rewrite 55 as 5 * 11

-5 * 11t + 5 * 30

Finally, factor out the common term, which in this case is -5.

The finalized answer to this problem is -5 (11t - 30).

Answer:

F(p) = 500 + 0.5p

Step-by-step explanation:

Given that :

Bonus point on first purchase = 500

Number of points earned for every 2 dollar spent = 1

Points earned as a function of amount spent :

Bonus point + points earned per dollar

Number of points earned per dollar = 1 / 2

Let p = amount spent

F(p) = function representing the points earned

Hence,

F(p) = 500 + 0.5p

Step-by-step explanation:

The value of constant 'k' will be [tex]\frac{1}{3}[/tex].

Given equation in the question is,

[tex]\frac{1}{3}\times (x-k)=kx[/tex]

Further solve the expression for the solution of the equation.

[tex]\frac{3}{3}\times (x-k)=3kx[/tex]

[tex](x-k)=3kx[/tex]

[tex]x-3kx-k=3kx-3kx[/tex]

[tex]x-3kx-k=0[/tex]

[tex]x(1-3k)=k[/tex]

[tex]\frac{x(1-3k)}{(1-3k)}=\frac{3kx}{1-3k}[/tex]

[tex]x=\frac{3kx}{(1-3k)}[/tex]

Since, equation has no value, denominator will be zero.

[tex]1-3k=0[/tex]

[tex]1=3k[/tex]

[tex]k=\frac{1}{3}[/tex]

     Therefore, Option (D) will be the correct option.

Answer:

B ;  2x^3-4x^2-x+\frac{14}{x+6}

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let A, B and C be any integer or function. According to distributive property;

A(B+C) = AB + AC

From the expression, you can see that A is distributed over B and C during the expansion.

Based on this same concept, the equation that  demonstrates the distributive property from the given options is 7(1+6) = (7x1) + (7x6)

From the equation, you can see that 7 is distributed over 1 and 6 to give 7(1) + 7(6).

The remaining options demonstrates the commutative property.

Answer:

[tex]\dfrac{1}3[/tex]

Step-by-step explanation:

Given that:

Part of pan of brownies eaten by Rodriguez family = [tex]\frac{1}{3}[/tex]

One part of the remaining pan of brownies will be taken to the block party.

And the other part of the remaining pan of brownies will be given to the co-workers.

To find:

How much of the whole pan of brownies will be in each plate?

Solution:

First of all, let us find the remaining part of brownies after the family ate [tex]\frac{1}{3}[/tex] part of the pan.

Remaining = [tex]1-\frac{1}{3}=\frac{2}{3}[/tex]

Now, from the remaining pan of brownies, they are divided in 2 halves.

These part will be equal to:

[tex]\dfrac{\frac{2}{3}}{2} = \bold{\dfrac{1}{3}}[/tex]

Therefore, the answer is:

[tex]\dfrac{1}3[/tex]

Answer:

Tickets to sit on the bench (b) = 150

Tickets to sit on the lawn (l) = 200

Step-by-step explanation:

Tickets to sit on a bench (b)cost $75 each.

Tickets to sit on the lawn (l) cost $40 each

350 tickets had been sold

$19,250 had been raised through tickets sales

This forms a simultaneous equation:

b + l = 350 ... (i)

75b + 40l = 19,250 ... (ii)

Multiplying (i) by 40 and (ii) by 1 we get;

40b + 40l = 14,000 ... (i)

75b + 40l = 19,250 ... (ii)

Subtracting (ii) - (i) we get;

35b = 5250

b = 5250 ÷ 35 = 150

Answer:

Step-by-step explanation:

(22 - 7y + 6) - (-4y² + 3y + 5) = 22 + -7y + 6 + 4y² - 3y  - 5
