Answer: 3 3/7

Step-by-step explanation:

6 - 2 4/7

6 is the same thing as 5 7/7

5 7/7 - 2 4/7 = 3 3/7

Answer:

The solution to the system of linear equations is:

(x, y) = (-2, 8)

Hence, y - 2x = 12 and x - 2y = -18  has the ordered pair (-2,8) as its solution. Thus, option A is correct.

Step-by-step explanation:

Checking the first system of equations

y - 2x = 12

x - 2y = -18

solving the first system of equations

[tex]\begin{bmatrix}y-2x=12\\ x-2y=-18\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}y-2x=12\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y-4x=24[/tex]

[tex]\begin{bmatrix}2y-4x=24\\ -2y+x=-18\end{bmatrix}[/tex]

adding the equations

[tex]-2y+x=-18[/tex]

[tex]+[/tex]

[tex]\underline{2y-4x=24}[/tex]

[tex]-3x=6[/tex]

[tex]\begin{bmatrix}2y-4x=24\\ -3x=6\end{bmatrix}[/tex]

solving -3x=6 for x

[tex]-3x=6[/tex]

Divide both sides by -3

[tex]\frac{-3x}{-3}=\frac{6}{-3}[/tex]

Simplify

[tex]x=-2[/tex]

[tex]\mathrm{For\:}2y-4x=24\mathrm{\:plug\:in\:}x=-2[/tex]

[tex]2y-4\left(-2\right)=24[/tex]

[tex]2y+8=24[/tex]

Subtract 8 from both sides

[tex]2y+8-8=24-8[/tex]

Simplify

[tex]2y=16[/tex]

Divide both sides by 2

[tex]\frac{2y}{2}=\frac{16}{2}[/tex]

Simplify

[tex]y=8[/tex]

Therefore, the solution to the system of linear equations is:

(x, y) = (-2, 8)

Hence, y - 2x = 12 and x - 2y = -18  has the ordered pair (-2,8) as its solution. Thus, option A is correct.

Answer: 3n - 1

Step-by-step explanation:

n = the number

3n - 1

One less is subtracting one.

Answer:

[tex]1-3[/tex]n

Step-by-step explanation:

One less 3 times a number.

1 less is 1-.

3 times a number would be 3n.

So, we get

[tex]1-3n[/tex]

Answer:

B.) 8 times

Step-by-step explanation:

you have to expect an equal amount from each #. divide 48 by 6 (because the cube has #s 1-6) that's how you get 8.

Answer:

He should play for 12 days

Step-by-step explanation:

Answer: y = 2   x = -2

Step-by-step explanation:

-x + y = 4

x + 3y = 4

Since x and -x are opposite, we can use the system of elimination

To do that, we add the first equation and the second equation together

-x + y = 4

      +

x + 3y = 4

      ↓

4y = 8

Now we solve for y

4y = 8

Divide both sides by 4

y = 2

Since we now know y, we can solve for x by substituting y for 2 in one of the equations.

x + 3y = 4

Substitute y for 2

x + 3 (2) = 4

x + 6 = 4

Subtract 6 from both sides

x = -2

Hope I helped! And sorry if I repeated somethings.

Answer:

i think its D

Step-by-step explanation:

The amount she wants to donate is 593, and she has 418 already so subtract that from 593 to get 175, and divide that 175 by 12.50 to get 14 days, and the solid circle means greater than or equal to 14, so it should be D.

Answer:

x = 135°

Step-by-step explanation:

104 + 44 + 77 = 225

360 - 225 = 135

A square has to have 360 degrees, right? SO, all quadrilaterals have to be 360 degrees.

have a good day! :)

Answer: 8 is b, 5 is a, 6 is c, and 7 is b

Step-by-step explanation:

Answer:

Step-by-step explanation:  3root5x^2 + 25x - 10root5 = 0

3xroot5 + 25x - 10root5 = 0      [ root x^2 = x]

28x root5 = 10 root5         [ -10root5 turns to 10 root5 when transferred to RHS]

28x root 5/root5 =10

28x=10

x = 10/28

x = 0.35

Step-by-step explanation:

We need to divide:

$60 ÷ 15 = 4

The required ratio of essential oils to jojoba oil is 1:24.

Given that,
You include 1/2 tablespoon of essential oils in a solution for every 12

tablespoons of jojoba oil.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
tablespoon of essential oils = 1/2
tablespoons of jojoba oil = 12
Ratio = [1 / 2] / 12
Ratio = 1 / [2 × 12]
Ratio = 1 / 24

Thus, the required ratio of essential oils to jojoba oil is 1:24.

Answer:

Step-by-step explanation:

first lets put this in standard form to make it easier

[tex]7x^{3}[/tex] - [tex]5x^{2}[/tex] - 4x + 10

this form is the standard form (exponents go from greatest to least)

The degree in this polynomial is the highest exponent

So the degree is 3

There are 4 terms in this equation

7x^3

-5x^2

-4x

and 10
