Write an expression equivalent to (6x + 4y) – 2y by combining like terms. Enter the numbers in the boxes

Consider the two numbers as

x and y

. From the given data, we write:

x−y=3

x+y=13

From the first equation, we determine a value for x.

x−y=3

Add y to both sides.

x=y+3

In the second equation, substitute x with (y+3).

x+y=13

(y+3)+y=13

Open the brackets and simplify.

y+3+y=13

2y+3=13

Subtract 3 from each side.

2y=10

Divide both sides by 2.

y=5

In the first equation, substitute y with 5.

x−y=3

x−5=3

Add 5 to each side.

Answer:

 = $ 49.5

Step-by-step explanation:

We are given;

Required to determine the amount paid

Taking the retail price as 100%

Then, amount paid will be (100 % - 10%) 90% of the retail price

Therefore;

Amount paid = 90% × $ 55

                     = 0.9 × $ 55

                     = $ 49.5

Thus, the employee paid $ 49.5 for the book.

Answer:

Jared offer $6,000.

Step-by-step explanation:

Given:

A used car is for sale for $24,000. Jared took a chance and offered the owner 1/4 of the selling price.

Now, to find the price Jared offer.

Selling price = $24,000.

Jared offer = [tex]\frac{1}{4}[/tex]  of selling price.

So, to get the price Jared offer:

[tex]\frac{1}{4}\ of\ \$24000[/tex]

[tex]=\frac{1}{4} \times 24000[/tex]

[tex]=\frac{24000}{4}[/tex]

[tex]=\$6000.[/tex]

Therefore, Jared offer $6,000.

Answer:

The graph that passes through (-3,-3), (-3,0), and (-3,3) does not represents a linear function.

Step-by-step explanation:

The graph that passes through (-3,-3), (-3,0), and (-3,3) does not represents a linear function. Because if we tried to find the slope for either two pairs of these coordinates. The slope would equal infinity

Lets say we find the slope of (-3,-3) and (-3,0)

[tex]\frac{-3-0}{(-3)-(-3)} =\frac{-3}{0}[/tex]  Slope = [tex]\infty}[/tex]

Now lets say we find the slope of (-3,0) and (-3,3)

[tex]\frac{0-3}{(-3)-(-3)} =\frac{-3}{0}[/tex] Slope = [tex]\infty[/tex]

So now we can see that both lines of each slope is parallel to the y-axis which means that the lines a Undefined Slope (also known as Infinite Slope).

The perimeter of the garden is 57.14 m and

the total area of the garden is 178.28 sq. m.

Solution:

Given length of the rectangle = 16 m

Width of the rectangle = 8 m

Radius of the semi-circle = half of the width of the rectangle

Radius = 4 cm

Perimeter of the garden is two lengths of the rectangle and 2 curve sides of the semi-circle.

Perimeter = [tex]2l+2(\frac{2\pi r}{2} )[/tex]

               = [tex]2l+2\pi r[/tex]

               = [tex]2(16)+2\times\frac{22}{7}\times4[/tex]

               = 32 + 25.14

               = 57.14 m

Total area of the garden is the area of the rectangle and area of the two semi-circles.

Area of the garden = [tex](l\times w)+ 2(\frac{\pi r^2}{2})[/tex]

                              = [tex](l\times w)+ \pi r^2[/tex]

                              = [tex]16\times8+\frac{22}{7} \times 4\times 4[/tex]

                              = 128 + 50.28

                              = 178.28 square meter

Hence, the perimeter of the garden is 57.14 m and

the total area of the garden is 178.28 sq. m.

Answer:

s = 20   F = 100    T = 60

Step-by-step explanation:

F = 5s                F + s + T = 180

T = 5s - 40

I picked numbers until I found the one that worked. For me, 20 worked for the second angle.

The measure of first angle, second angle, and the third angle is 100, 20 and 60.

Given that,

Based on the above information, the calculation is as follows:

F = 5s                

F + s + T = 180

T = 5s - 40

Now

5s + s + 5s - 40 = 180

11s = 220

s = 20

F = 100

T = 100 - 40

= 60

Trapezoid JKLM is shown below.

What is the length, in centimeters, of KL ?

A. 12 cm

B. 10 cm

C. 9 cm

D.  6 cm

The mentioned figure is attached.

Answer:

[tex]\large\boxed{option\text{ B. }(\overline{KL})=10cm}[/tex]

Explanation:

1. KL is the hypotenuse of a right triangle; hence, you can use Pythagora's theorem to find its length.

2. The height 8 cm is one leg of the right triangle.

3. The other leg may be found by difference:

     [tex]\overline{ML} -\overline{JK}=15cm-9cm=6cm[/tex]

4. Now you can use Pythagora's theorem:

[tex]hypotenuse^2=(leg_1)^2+(leg_2)^2\\ \\ (\overline{KL})^2=(8cm)^2+(6cm)^2\\ \\ (\overline{KL})^2=64cm^2+36cm^2=100cm^2\\ \\ (\overline{KL})=10cm[/tex]

Answer:

These rates DO NOT  form a proportion.

Step-by-step explanation:

Two quantities P and Q are said to be in proportion is and only if:

[tex]\frac{P}{Q} = k[/tex]  for all values of P and Q.

here, k = Proportionality Constant.

Case 1: when P =  21 miles , Q  = 6 hours

[tex]\frac{P}{Q} = \frac{21}{6} = 3.5[/tex]

⇒  k 1 = 3.5

Case 2: when P =  14.3 miles , Q  = 3 hours

[tex]\frac{P}{Q} = \frac{14.3}{3} = 4.76[/tex]

⇒  k 2 = 4.76

As we can see in both the cases, k 1 ≠ k 2

Hence, P is NOT PROPORTIONAL to Q.

So, these rates DO NOT  form a proportion.

Answer: 3.12 x 10^-3

Step-by-step explanation:

Answer: ( 11, -2 )

Step-by-step explanation:

The mid point of a line is calculated using the formula:

M = ([tex]\frac{x_{1}+x_{2}}{2}[/tex] , [tex]\frac{y_{1}+y_{2}}{2}[/tex] )

From the question , the mid point is already given , substituting , we have :

(5 , - 7.5 ) = ([tex]\frac{x-1}{2}[/tex] , [tex]\frac{y-13}{2}[/tex] )

Equating the x component to x and the y component to y , we have

5 = [tex]\frac{x-1}{2}[/tex]

x - 1 = 10

x = 11

Also

- 7.5 = [tex]\frac{y-13}{2}[/tex]

-15 = y - 13

-15 + 13 = y

Therefore : y = -2

Therefore : the location of point P is ( 11, -2 )

The value of numerators are 3 and 5

Solution:

Let the numerators of two fractions be x and y

Two fractions have denominators 4 and 6. Their sum is 19/12

Therefore,

[tex]\frac{x}{4} + \frac{y}{6} = \frac{19}{12}[/tex]

Cross multiply L.H.S to get simplified

[tex]\frac{6x+4y}{24} = \frac{19}{12}\\\\6x + 4y = 38 ------- eqn 1[/tex]

If the numerators are switched their sum is 7/4

Therefore,

[tex]\frac{y}{4} + \frac{x}{6} = \frac{7}{4}[/tex]

On simplification, we get

[tex]\frac{6y + 4x}{24} = \frac{7}{4}\\\\4x + 6y = 42 -------- eqn 2[/tex]

Solve eqn 1 and eqn 2

Multiply eqn 1 by 4

24x + 16y = 152 --------- eqn 3

Multiply eqn 2 by 6

24x + 36y = 252 ---------- eqn 4

Subtract eqn 3 from eqn 4

24x + 36y = 252

24x + 16y = 152

( - ) -------------------

20y = 100

Substitute y = 5 in eqn 1

6x + 4(5) = 38

6x = 38 - 20

6x = 18

Thus the value of numerators are 3 and 5

Answer:

3,600 from $26 tickets  and  1,400 from $40 tickets.  

Step-by-step explanation:

Let x = number of $26 tickets and y= number of $40 tickets

x + y = 5000  ⇒ x = 5000 - y

26x + 40y = 149,600

26(5000 - y) + 40y = 149600

130,000 - 26y + 40y = 149600

14y = 19600

y = 19600/14 = 1,400

x = 5000 - 1400 = 3,600

So, 3,600 from $26 tickets  and  1,400 from $40 tickets.

To determine the number of tickets sold at each price, set up a system of equations using the given information and solve for the variables.

To determine how many tickets should be sold at each price, we can set up a system of equations using the given information.

Let's assume the number of $26 tickets sold is x and the number of $40 tickets sold is y.

The total number of tickets sold is x + y, so we have the equation x + y = 5000.

The revenue generated from $26 tickets is 26x, and the revenue generated from $40 tickets is 40y. The total revenue

is given as $149,600, so we have the equation 26x + 40y = 149600.

Solving this system of equations will give us the values of x and y.

Step-by-step explanation:

Given:

Darcy harvest 8 3/4 acres of corn every 5/6 of an hour.

Now, to find the acres per hour it takes to harvest.

Darcy harvest = [tex]8\frac{3}{4}=\frac{35}{4}\ acres.[/tex]

The time he took to harvest = [tex]\frac{5}{6}\ hour.[/tex]

So, to get the acres per hour we put formula:

[tex]Distance = \frac{35}{4}\ acres.[/tex]

[tex]Time=\frac{5}{6}\ hour.[/tex]

[tex]Speed=\frac{distance}{time}[/tex]

[tex]Speed=\frac{\frac{35}{4}}{\frac{5}{6}}[/tex]

[tex]Speed=\frac{35}{4}\times \frac{6}{5}[/tex]

[tex]Speed=\frac{210}{20}[/tex]

[tex]Speed=\frac{21}{2}[/tex]

then,

u+v = < a+c, b+d >

Basically we add the x coordinates separately and the y coordinates are added separately.
