Answer: Choice B

x+6y = 29  and  x+3y = 24.5

==============================================

Explanation:

x is the cost of a throw blanket

On top of this cost is the cost to embroider letters on it

Your name has 6 letters so it costs you an extra 6y dollars. Overall, you pay x+6y dollars. It says that your cost is $29

So that's where x+6y = 29 comes from.

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

Similarly, your friend also pays x dollars for the blanket itself plus an extra 3y dollars for the 3 letters in their name. Overall, they pay x+3y dollars. We're told they spent $24.50 which is where the equation x+3y = 24.5 comes from.

Answer:

2nd one = x + 6y = 29 , x + 3y = 24.5

Step-by-step explanation:

5x + 3 = x + 11

4x=8

x=2

!!!!!

[tex]5x + 3 = x + 11 \\ 5x + 3 - x = 11 \\ 4x + 3 = 11 \\ 4x = 11 - 3 \\ 4x = 8 \\ x = \frac{8}{4} \\ x = 2[/tex]

Answer:

B

Step-by-step explanation:

that is a linear equation, therefore it makes a line, eliminating choices C and D.

Lines can literally Any x or y. So it would be B, a set of all the solutions to the equations.

Answer:

5

Step-by-step explanation:

since the 2 points have y values, line ST is parallel to x axis.

we just need to look for the difference between the two x values of the two points. I.e. 9-4 = 5

Answer:

x = [tex]\frac{11}{c}[/tex]

Step-by-step explanation:

Given

cx - 4 = 7 ( add 4 to both sides )

cx = 11 ( isolate x by dividing both sides by c )

x = [tex]\frac{11}{c}[/tex]

Answer:

Empty square = +

Empty Circle = ÷

Step-by-step explanation:

In order to eliminate the extra numbers from the equation you have to do the opposite of the problem. So...

-6x-1=5

-6x -1+1 = 5+1 (eliminating the 1 from the -6x side and adding it to the other side)

-6x = 6

-6x ÷ -6 = 6 ÷ -6 ( eliminating the-6 so that one side just has x)

so... x= -1

Answer: Option B is your correct answer.

Answer:

1/8 of the original sum still remains.

Step-by-step explanation:

If you spend 3/4 of what you have, you have 1/4 left.

Now you spend 1/2 of that 1/4, so basically divide 1/4 by 2. When dividing fractions you can multiply the fraction by the reciprocal of the other fraction.

[tex]\frac{1}{4}[/tex] ÷ [tex]\frac{2}{1}[/tex] = [tex]\frac{1}{4}[/tex] * [tex]\frac{1}{2}[/tex]

= 1/8

So I think 1/8 of the original sum still remains.

Hope this helped, please mark brainliest if possible. Have a nice day.

Answer:

a) is the correct answer.

Answer:

48 years old

Step-by-step explanation:

a + w = 62

a+3 = 3(w+3) =>a+3=3w+9

=> a-3w = 6

a+ w = 62

a- 3w= 6

________-

4w = 56

w = 14

so, the Aini's age now is 62-14 = 48 years old

Answer:

x=20, y=17, and z=6 or (20,17,6)

Step-by-step explanation:

Hi there!

We're given the system of equations:

2x+z=46

3z=18

2y+z=40

and we need to solve for x, y, and z

first, let's find the value of z, as we have z by itself (no other variables) in 3z=18

divide both sides by z

z=6

the value of z is found :)

now we can use z=6 to find the value of the other variables; for example, plug z as 6 into 2x+z=46 to solve for x

2x+6=46

subtract 6 from both sides

2x=40

divide by 2

x=20

Finally, let's find y

once again, we can substitute z as 6 in the equation 2y+z=40 to find y

2y+6=40

subtract 6 from both sides

2y=34

divide by 2

y=17

so the answer is: x=20, y=17, and z=6; if you need it in a point it's (20,17,6)

Hope this helps! :)

Answer:

A = 9x² + 12x

Step-by-step explanation:

The area (A) of the rectangle is calculated as

A = height × width

  = 3(3x² + 4x) ← distribute parenthesis by 3

   = 9x² + 12x

Answer:

For the blue one:

A1=length*breadth

   =3*3x^2

   =9x^2

For pink:

A2=length*breadth

    =3*4x

    =12x

So the total area is:

A=A1+A2

  =9x^2+12x

Step-by-step explanation:

Answer:

In 10 hours, the population is 6050 bacteria. In 20 hours, the population is 732050 bacteria.

Step-by-step explanation:

Bacterial populations can be assumed to grow exponentially. In 5 hours, since the population will have multiplied by 11, in 10 hours it will have multiplied by 121 (11^2) and by 14641 (11^4).

50 * 11 * 11 = 6050

50 * 11 * 11 * 11 * 11 = 732050

Answer:

Step-by-step explanation:

550 = 50 [tex]x^{5}[/tex]

11 =   [tex]x^{5}[/tex]

ln(11) = 5 ln(x)

x = [tex]e^{ln(11)/5}[/tex]

x = 1.615

10 hours ....

A= 50 ([tex]1.615^{10}[/tex] )

A= 50 ([tex]1.615^{10}[/tex] )

A=6050

20 hours ....

A= 50 ([tex]1.615^{20}[/tex] )

A= 50 ([tex]1.615^{20}[/tex] )

A=732,050

$50.00÷7hours=×$

$50.00÷7hours= 7.25

7.25 he charges per hour

Jeevan is not correct, the answer could be 4.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that Jessica's teacher asks a class to find the largest number that is smaller than 4.5.

Since Jessica's friend Jeevan gives the answer 4.4.

Therefore, we can see that 4.4 is not a whole number thus, it isn’t the largest number that is also less than 4.5.

The correct answer could be 4.

Answer:

perpendicular

Step-by-step explanation:

start but putting each line into the standard line format

2x-y=-5

-y=-2x-5

y=2x+5

x+2y=-6

2y=-x-6

y=-(1/2)x-3

if lines are parallel the slopes would be the same. 2 is not equal to -1/2

if lines are perpendicular the slope of one would be the opposite inverse of the other.

negative inverse of 2 = - (1/2)

so the lines are perpendicular

Given:

The expressions are:

[tex]\sqrt[3]{24},\sqrt{48},\sqrt[3]{54},\sqrt{45}[/tex]

To find:

The simplified form of each expression.

Solution:

We have,

[tex]\sqrt[3]{24}[/tex]

It can be written as:

[tex]\sqrt[3]{24}=\sqrt[3]{2\times 2\times 2\times 3}[/tex]

[tex]\sqrt[3]{24}=2\sqrt[3]{3}[/tex]

Similarly,

[tex]\sqrt{48}=\sqrt{2\times 2\times 2\times 2\times 3}[/tex]

[tex]\sqrt{48}=(2\times 2)\sqrt{3}[/tex]

[tex]\sqrt{48}=4\sqrt{3}[/tex]

And,

[tex]\sqrt[3]{54}=\sqrt[3]{2\times 3\times 3\times 3}[/tex]

[tex]\sqrt[3]{54}=3\sqrt[3]{2}[/tex]

In the same way,

[tex]\sqrt{45}=\sqrt{3\times 3\times 5}[/tex]

[tex]\sqrt{45}=3\sqrt{5}[/tex]

Therefore, the required pairs are:

[tex]\sqrt[3]{24}\to 2\sqrt[3]{3}[/tex]

[tex]\sqrt{48}\to 4\sqrt{3}[/tex]

[tex]\sqrt[3]{54}\to 3\sqrt[3]{2}[/tex]

[tex]\sqrt{45}\to 3\sqrt{5}[/tex]

Given:

Scott can run 20 km in 85 minutes.

To find:

How long will it take Scott to run 52 km?

Solution:

Let us consider x be the number of minutes it will take him to run 52 km.

We know that,

[tex]Speed=\dfrac{Distance}{Time}[/tex]

By using this formula, we get

[tex]Speed=\dfrac{20}{85}[/tex]           ...(i)

[tex]Speed=\dfrac{52}{x}[/tex]             ...(ii)

On equating (i) and (ii), we get

[tex]\dfrac{20}{85}=\dfrac{52}{x}[/tex]

[tex]20\times x=52\times 85[/tex]

[tex]20x=4420[/tex]

On dividing both sides by 20, we get

[tex]x=\dfrac{4420}{20}[/tex]

[tex]x=221[/tex]

Hence, it will take 221 minutes to run 52 km.

Answer:

Mean = 7

Step-by-step explanation:

Given the following data;

Number of games = 8

Scores = 5, 11, 9, 9, 4, 5, 6, 7

We would sum all the scores together to get a total score.

Total scores = 5 + 11 + 9 + 9 + 4 + 5 + 6 + 7 = 56

Now, to find the mean;

[tex] Mean = \frac {total \; scores}{number \; of \; games} [/tex]

Mean = 56/8

Mean = 7

Answer:

7 is the mean score.

Step-by-step explanation:

Now we have to,

→ find the required mean score.

The given scores are,

→ 5, 11, 9, 9, 4, 5, 6, 7

→ Numbers = 8

Then the mean score will be,

→ (5 + 11 + 9 + 9 + 4 + 5 + 6 + 7)/8

→ 56/8 = 7

Hence, the mean score is 7.

6)  a number x increased by -18

             x + (-18)    

   or       x -  18

7)    x subtracted from its reciprocal

              1/x  - x  

8)   two numbers have the sum of 11, one number is q find the other

             x + q = 11

             x + q - q = 11 - q       q - q = 0

              x + 0  = 11 - q

              x = 11 - q

9)    six is added to 4 times a number equals 42, find the number

      ( I don't know the six steps discussed in class.  This is how I would do it)

             6 + 4x = 42

             6 - 6 + 4x = 42 - 6              isolate the variable,  - 6 from both sides

             0 + 4x = 36                            6 - 6 = 0,  43 - 6 = 36, solve for x

                4x/4 = 36/4                      divide both sides by 4

                  1x  =  36 /4                        4/4 = 1

                  x  =   9

Answer:

4/10=40%

Step-by-step explanation:

Answer:

Approximately 0.0121 will be left after 15 days.

Step-by-step explanation:

We can write an exponential function to model the situation. The standard exponential function is given by:

[tex]y=a(b)^x[/tex]

Let x represent the amount of days. Since the initial amount is 3,820 pounds, a = 3820. It decays at a rate of 57% per day. So, after one day, it will only have 100% - 57% = 43% or 0.43 of its previous amount. So, b = 0.43.

Hence, our function is:

[tex]y=3820(0.43)^x[/tex]

After 15 days, x = 15. Substitute and evaluate:

[tex]y(15)=3820(0.43)^{15}\approx 0.0121\text{ pounds}[/tex]
