Gil charges $5 per bracelet plus $2 for each string colour. If Gil makes 3 bracelets
with x colours, write an expression that represents how much money Gil makes.

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:

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:

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:

the answer is 32 square inches

Explanation:

Divide the shape into a rectangle and a square

Area of the rectangle = 20 square inches

Are of the square = 12 square inches

Add both the areas

= 20 square inches + 12 Square inches

= 32 square inches

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:

3 11 19 27 35 43 51 59 67 75 83 91 99 107

Step-by-step explanation:

Answer:

x= -4

Step-by-step explanation:

I hope this helps, have a great day/night :) !

Answer:

x = -4

Step-by-step explanation:

2x + 3 = -6x - 29

2x + 6x = -3 - 29

8x = -32

x = -32/8

x = -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:

The answer is 16.

Step-by-step explanation:

When you calculate the ratio of 42:28, you would get 3:2. divide 24 by 3, and you get 8. Then multiply 2 by 8 you get 16.

Answer:

The y-intercept is -2 and the equation is y=x-2

Step-by-step explanation:

-That's where the line crosses the y axis.

-The equation is y= x -2 because it has a rise/run of 1/1 which is just 1 and the y intercept is -2

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

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
