Solve The Equation (3 X/2)(3 X/4)=3^6 Please Help!! Need Done Asap!

Answers

Answer 1

Answer:

x=18√2 or x=−18√2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

9/8x^2=729

Step 2: Divide both sides by 9/8.

9/8x^2/9/8=729/9/8

x^2=648

Step 3: Take square root.

x=±√648

x=18√2 or x=−18√2

Answer 2

Answer:

x = 8

Step-by-step explanation:

x/2 + x/4 = 6

2x/4 + 1x/4 = 6

3x/4 = 6

3x = 24

x = 8

Use the linear combination method to solve the system of equations.

–2.1x + 4y = 5.3

2.1x – 5.5y = –0.2

What is the solution to the system?

(, )

Answers

Answer:

The solution to the system of equations is:

[tex]x = -9[/tex],   [tex]y=-3.4[/tex]

Step-by-step explanation:

Given the system of equations

-2.1x + 4y = 5.3

2.1x - 5.5y = -0.2

Solving the system of equations using the linear combination method

[tex]\begin{bmatrix}-2.1x+4y=5.3\\ 2.1x-5.5y=-0.2\end{bmatrix}[/tex]

adding the equations

[tex]2.1x-5.5y=-0.2[/tex]

[tex]+[/tex]

[tex]\underline{-2.1x+4y=5.3}[/tex]

[tex]-1.5y=5.1[/tex]

solving -1.5y = 5.1 for y

[tex]-1.5y=5.1[/tex]

Divide both sides by -1.5

[tex]\frac{-1.5y}{-1.5}=\frac{5.1}{-1.5}[/tex]

[tex]y=-3.4[/tex]

substitute y = -3.4 in 2.1x - 5.5y = -0.2

2.1x - 5.5y = -0.2

2.1x - 5.5(-3.4) = -0.2

2.1x + 18.7 = -0.2

2.1x = -0.2-18.7

2.1x = -18.9

Divide both sides by 2.1

[tex]\:\frac{2.1x}{2.1x}\:\:=\:\:\frac{-18.9}{2.1}[/tex]

[tex]x = -9[/tex]

Therefore, the solution to the system of equations is:

[tex]x = -9[/tex],   [tex]y=-3.4[/tex]

Find the nth term for the
following sequences:
Q2)3, 9, 15, 21

Answers

Answer:

[tex]a_{n}[/tex] = 6n - 3

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 9 - 3 = 15 - 9 = 21 - 15 = 6

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 3 and d = 6, then

[tex]a_{n}[/tex] = 3 + 6(n - 1) = 3 + 6n - 6 = 6n - 3

Solve the system y=x-3 y=-2x+3

Answers

Answer:

x = 2, y= -1 Or (2, -1)

Step-by-step explanation:

Let’s solve the system using substitution. First we can set the equations equal to each other:

x-3= -2x +3

Now solve for x

3x-3= 3

3x = 6

x=2

Now that we have x, we can plug it back into one of the original equations to get y

y= x-3

y= 2-3

y = -1

Finally, the solution to the system of equations is (2, -1).

Answer:

(2,-1)

Step-by-step explanation:

1.) y = x - 3

    y = -2x + 3

2.) Multiply top equation by 2

    2y = 2x - 6

    y = -2x + 3

3.) Add equations

    3y = -3

4.) Divide 3 from each side

     y = -1

5.) Substitute -1 for y in second equation

    -1 = -2x + 3

6.) Solve

     -4 = -2x

     x = 2

Therefore, (2, -1)

Sally can paint a room in 9 hours while it takes Steve 3 hours to paint the same room. How long would it take them to paint the room if they worked together?

Answers

You can solve this one by adding their rates, but you have to invert the numbers they give you to find the rate. Rate is measured in something per unit of time, and "per" indicates division. So the rates are: 1/3 of an hour (Sally) and 1/6 of an hour (Steve). So add the rates: 1/3 + 1/6 = 1/2. (1/3 is 2/6, and 2/6 + 1/6 = 3/6). Since their combined rate is 1/2 of a room in one hour, it takes them two hours to paint the room.

This answer makes sense: It takes Sally three hours by herself; with Steve's help, she's faster, but not THAT much faster, because he's pretty slow. You can often spot-check word problem answers like this by giving it a common sense once-over. If we came up with four hours, that would clearly be wrong: it should take her LONGER if she's getting help.

Answer:

2 1/4 hours

Step-by-step explanation:

Okay, so- The first thing I did was see how much they got done per hour. Like this:

Sally  ⇒

3 hours = 1 room

1 hour = 1/3 of the room

Steve ⇒

9 hours = 1 room

1 hour = 1/9 of the room

Sally + Steve ⇒  

1 hour = 1/3 + 1/9 = 3/9 + 1/9 = 4/9

So, they get 4/9 of a room done in 1 hour.

Number of hours needed ⇒

1 ÷ 4/9 = 2 1/4  

Answer: They need 2 1/4 hours to paint the room.

We can write 7 + 2 + 1 in two different ways.

a)

7 + 1 + 2

b)

1 + 7 + 2

Step-by-step explanation:

The commutative property of addition states that we can add the numbers in any order and get the same answer.

For example, if we add 'a' and 'b' together, the commutative property of addition states that we would get the same answer whether we add a + b or b+a.

In other words,

a + b = b + 1

In our case, we are given

7 + 2 + 1

According to the commutative property of addition, we can add the number in any order and get the same answer.

Therefore, we can write 7 + 2 + 1 in two different ways.

a)

7 + 1 + 2

b)

1 + 7 + 2

Verification:

Thus, the answer will remain the same in any order.

i.e.

7 + 2 + 1 = 7 + 1 + 2 = 1 + 7 + 2
