Step-by-step explanation:

AB + BC = AC

9x + 7  - 3x + 20 = 39    { combine like terms}

9x  -3x + 7 + 20 = 39

            6x + 27 = 39 {Subtract 27 from both sides}

                     6x = 39- 27

                      6x = 12   {divide both sides by 6}

                    6x/6 = 12/6

x = 2

Answer : The value of x is 100.

Step-by-step explanation :

According to the question, the FH makes a line in which point G is present in between the line FH.

The diagram is shown below.

Given:

FG = (2x) meters

GH = 1000 meters

FH = 1200 meters

Now we have to calculate the value of x.

As we know that:

FH = FG + GH

Now putting all the given values in this expression, we get:

1200 = 2x + 1000

1200 - 1000 = 2x

200 = 2x

x = 100

Therefore, the value of x is 100.

Share is 4 times as old as Marcos. If the sum of their age is 45, which equation could best be used to find their ages?

Answers

Answer:

5x = 45

Step-by-step explanation:

x represents marcos

4x represents Share

5x = 45

x = 9

4x = 36

Share is 36 and Marcos is 9

Answer:

4x+x =45

Step-by-step explanation:

x would be marcos, since we do not know his age, and share is 4x that amount, so you would have 4x(shares age) plus x(marcos age) to get your answer.

The marked price of an article is Rs.2080. After allowing d% discount and levying
(d-2)% VAT the cost of the article becomes Rs.1997.84. Find the rate of VAT?​

Answers

Answer:

13%

Step-by-step explanation:

Given:

MP = 2080Discount = d%VAT = (d-2)%Cost = 1997.84

Apply discount:

2080 - d% = 2080*(1 - 0.01d)

Add VAT:

2080*(1 - 0.01d) + (d - 2)% 2080*(1 - 0.01d) * (1 + (d -2)/100)2080*(1 - 0.01d) * (0.98 + 0.01d) = 1997.84(1 - 0.01d)(0.98 + 0.01d) = 1997.84/20800.98 + 0.01d - 0.0098d - 0.0001d² = 0.9605 - 0.0001d² + 0.0002d + 0.98- 0.9605 = 00.0001d²- 0.0002d - 0.0195 = 0d² - 2d + 195 = 0

Solving the quadratic equation we get:

d = 15

Then

VAT rate = 15 - 2 = 13%

From a full 50-liter container of a 40% concentration of acid, x liters are removed and replaced with 100% acid. (A) Write the amount of acid in the final mixture as a function of x (B) Determine the domain and range of the function (C) Determine if the final mixture is 50% acid PLEASE EXPLAIN...I DON'T UNDERSTAND THIS AT ALL

Answers

Answer:

A) 20+0.6[tex]x[/tex]

B) range is [0, 50] (i.e. both inclusive)

C) 8.33 litres

Step-by-step explanation:

Given that concentration of acid in 50 litre container is 40%.

Amount of acid in the container = 40% of 50 litres

Amount of acid in the container = [tex]\frac{40}{100} \times 50 = 20\ litre[/tex]

[tex]x[/tex] litres are removed.

Amount of acid removed = 40% of [tex]x[/tex] litre.

Now, remaining acid in the container = (20 - 40% of [tex]x[/tex]) litre

Now, replaced with 100% acid.

So, final acid in the container = (20 - 40% of [tex]x[/tex] + 100% of [tex]x[/tex] ) litre

Amount of acid in the final mixture:

[tex]20 - \dfrac{40}{100} \times x + \dfrac{100}{100} \times x\\\Rightarrow 20 +\dfrac{100-40}{100}x\\\Rightarrow 20 +\dfrac{60}{100}x[/tex]

Answer A) Amount of acid in the final mixture = 20+0.6[tex]x[/tex]

Answer B) [tex]x[/tex] can not be greater than 50 litres (initial volume of container) and can not be lesser than 0 litres.

so, range is [0, 50] (i.e. both inclusive)

Answer C)

Given that final mixture is 50% acid.

amount of acid = 50% of 50 litres = 25 litres

Using the equation:

[tex]20+0.6x =25\\\Rightarrow 0.6x =5\\\Rightarrow \bold{x =8.33\ litres}[/tex]

Solve the equation 5(2y - 1) - 2(3y)= 1

Answers

Answer:

y = 3/2

Step-by-step explanation:

5(2y - 1) - 2(3y) = 1

First we use distributive property:

10y - 5 - 6y = 1

because 5 × 2y = 10y

and -2 × 3y = -6y

Now we combine the like terms:

4y -5 = 1

because 10y - 6y = 4y

Now we have to send the -5 to the other side. (when we send it to the other side it becomes positive because right now it is negative)

4y = 1 + 5

Again we combine the like terms:

4y = 6

(because 5 + 1 = 6)

Now we have to send the 4 to the other side because we need to get the y value. (when we send it to the other sidr it will be divided)

y = 6/4

and we simplify:

y = 3/2

And we cannot simplify or do anything else. So that is the answer.

Answers

The total lease cost assuming that the deposit is nonrefundable is $14046.

What is Meant by Lease Cost?

The term "Leasing Costs" refers to all fees paid or benefits granted to a tenant under an existing lease or a new lease, including I commissions for leasing or brokerage services, (ii) direct payments, tenant improvement allowances, work letters, or free rent, and (iii) rent allowances or rent credits.

Given:

Length of lease: 24 months

MSRP of the car: $21,400

Purchase value of the car after lease: $17,100

So, Monthly payment= $479

So, Monthly payment after 24 month

= 11496

Thus, total lease cost =  Down payment + Security deposit + Acquisition

                                                                                                             fee

                                                               + payment for 24 months

Total lease cost = 1500+ 350+ 700+ 11496

                           = $14046

Hence, the lease cost is $14046.

7. Ara and Vartan each have a pomegranate tree growing in their backyards. Ara’s tree is two times taller than Vartan’s. If the total height of the two trees is 25 feet, then how tall is each tree?

Answers

Answer:

The height of Ara's tree is 50/3 feet while Vartan's tree is 25/3 feet high

Step-by-step explanation:

Represent Ara's tree with A and Vartan's with V

Given

[tex]A = 2V[/tex]

[tex]A + V = 25[/tex]

Required

Determine A and V

[tex]A = 2V[/tex]

[tex]A + V = 25[/tex]

Substitute 2V for A in [tex]A + V = 25[/tex]

[tex]2V + V= 25[/tex]

[tex]3V = 25[/tex]

Divide both sides by 3

[tex]V =\frac{25}{3}\ feet[/tex]

Recall that [tex]A = 2V[/tex]

So:

[tex]A = 2 * \frac{25}{3}\ feet[/tex]

[tex]A = \frac{2 * 25}{3}\ feet[/tex]

[tex]A = \frac{50}{3}\ feet[/tex]

Hence, the height of Ara's tree is 50/3 feet while Vartan's tree is 25/3 feet high

The width of a rectangle measures (3.1s – 1.6) centimeters, and its length
measures (7.2s – 4.6) centimeters. Which expression represents the perimeter, in
centimeters, of the rectangle?

Answers

Answer:

Expression for perimeter of rectangle is:

[tex]\bold{Perimeter = (20.6s-12.4)\ centimeters}[/tex]

Step-by-step explanation:

Width of rectangle is given as [tex]( 3.1 s - 1.6 )[/tex] centimeters and

length  of the rectangle is given as [tex](7.2s - 4.6)[/tex] centimeters.

To find:

The expression to represent the perimeter of rectangle in centimeters.

Solution:

First of all, let us have a look at the formula to calculate the perimeter of a rectangle.

Perimeter of a polygon is equal to sum of all the sides.

In rectangle, we have a total of 4 sides, 2 sides equal to the width and 2 sides are equal to the length of rectangle.

Therefore, perimeter of a rectangle is equal to twice the sum of width and length of the rectangle.

So, formula:

[tex]Perimeter = 2(l+w)[/tex]

Where [tex]l[/tex] is the length of rectangle and

[tex]w[/tex] is the width of rectangle.

Putting the values of length and width as given in the question statement to find its perimeter:

[tex]Perimeter = 2((3.1s-1.6) +(7.2s-4.6))\\\Rightarrow Perimeter = 2(10.3s-6.2)\\\Rightarrow \bold{Perimeter = (20.6s-12.4)\ centimeters}[/tex]

y = -4x + 10 y = -6x + 16 Substitution

Answers

Answer:

The answer to this problem is x = 3 and y = -2.

Step-by-step explanation:

To solve this problem, we first have to remember how to solve problems using substitution.  We first solve one equation completely in terms of another variable.  In this case, this has already been done for us - the first equation is in the form y = f(x).  Next, we should substitute this "value" or function for y into the other equation.  This process is modeled below:

y = -4x + 10

y = -6x + 16

If we substitute, we get:

-4x + 10 = -6x + 16

Now this is a simple one variable equation that we can solve easily.  First, we should add 6x to both sides, giving us:

2x + 10 = 16

Then, we should subtract 10 from both sides, yielding:

2x = 6

Finally, we can divide both sides by 2 to get:

x = 3

Now, we must plug in this value for x into one of our original equations (it doesn't matter which one we choose) to solve for the other variable, y.

y = -4x + 10

y = -4(3) + 10

y = -12 + 10

y = -2

Therefore, the answer to this problem is x = 3 and y = -2.

Hope this helps!

Answer:

x = 3

y = -2

Step-by-step explanation:

y = -4x + 10       first equation

y = -6x + 16        second equation

from the second equation:

6x = -y + 16

x = (-y + 16) / 6       third equation

substituying the value of the third equation into the first equation:

y = -4(-y+16)/6 + 10

y - 10 = -4(-y+16(/6

6(y-10) = -4(-y+16)

6*y + 6*-10 = -4*-y -4*16

6y - 60 = 4y - 64

6y - 4y = 60 - 64

2y = -4

y = -4/2

y = -2

from the third equation:

x = (-y + 16) / 6

x = (-(-2) + 16) / 6

x = (2+16)/6

x = 18/6

x = 3

Check:

from the first equation:

y = -4x + 10

-2 = -4*3 + 10

-2 = -12 + 10
