What is the answer for ?x+2y=4 3x+6y=18

Answer:

289feet²

Step-by-step explanation:

Area of a rectangle = length x breadth

area of a square = length²

area of the yard that is not covered by the hot tub and fire pit =

Area of the yard - (area of the hot tub + area of the fire pit)

Area of the yard = 20 feet² = 400 feet²

area of the hot tub =  6 feet² x 8 feet² = 48 feet²

area of the fire pit = 7 feet² x 9 feet² = 63 feet²

400 - (48 + 63) = 289 feet²

Answer: 1.5 tons

Step-by-step explanation:

Given

The recycling center collected 48,000 ounces of aluminum can

An ounce is the unit of weight and it can be expressed in tons as

[tex]1\ \text{ounce}=3.125\times 10^{-5}\ \text{tons}[/tex]

[tex]\therefore 48,000\ \text{ounces} \equiv\ 3.125\times 10^{-5}\times 48,000=1.5\ \text{tons}[/tex]

Answer:

7.4 in

Step-by-step explanation:

The diagonal divides the rectangle into 2 right triangles.

The diagonal is the hypotenuse and the length l is a leg ( adjacent) to angle

Using the cosine ratio in the right triangle

cos22° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{l}{8}[/tex] ( multiply both sides by 8 )

8 × cos22° = l , then l ≈ 7.4 in ( to the nearest tenth )

Answer:

The walkway around the pool makes the entire outer dimensions (outer border)  

x+9+2x3=x+15  and  x+8+2x3

hope this helps!  could i get brainliest plz?

The expressions to represent the dimensions of the outside border of the walkway is  (x + 12) meters for the length and (x + 11) meters for the width.

Given area : [tex]x^2 + 17x + 72[/tex]

The factored form of the polynomial is:

[tex]x^2 + 17x + 72[/tex]  = [tex]x^2 + 8x+9x+72[/tex]

                      = x(x+8)+9(x + 8)

                          =(x + 9)(x + 8)

So, the dimensions of the pool are (x + 9) meters and (x + 8) meters.

The length of the walkway = 3 meters wide

So, the length is added to each side of the pool.

Dimensions of the outside border of the walkway:

Length: (x + 9) + 3 = x + 12 meters

Width: (x + 8) + 3 = x + 11 meters

Therefore, the dimensions of the outside border of the walkway are

(x + 12) meters for the length and (x + 11) meters for the width.

Answer:

x = 10

Step-by-step explanation:

These angles are same side interior angles.

This means that (11x + 10) + (10x - 40) = 180

Solve for x:

11x + 10 + 10x - 40 = 180

21x - 30 = 180

Answer:

The total number of possible outcomes if the code has 3 letters is 64

Step-by-step explanation:

The keypad has only the letters A-D, that is, A,B,C,D.

To calculate the total number of possible outcomes if the code has 3 letters,

let these spaces represent the code _ _ _

For the first space, there are 4 possibilities (since we have 4 letters)

For the second space, we also have 4 possibilities (since there is no restriction on repetition)

Also, we have 4 possibilities for the last space.

Hence, the total number of possible outcomes if the code has 3 letters is 4×4×4 = 4³ = 64.

There are 64 total possible outcomes if the code has 3 letters

The number of letters is given as:

n = 4

The code makes use of three letters.

This means that:

So, the number of possible outcomes is:

Outcomes = 4 * 4 * 4

Evaluate the product

Outcomes = 64

Hence, there are 64 total possible outcomes if the code has 3 letters

Answer:

Step-by-step explanation:

If we were to put 12 - (-15), the two - would convert to a single +. Thus, the answer should be 12 + 15 which is 27.

If we were to put 24 × [tex]\frac{3}{4}[/tex], we would have to multiply 24 by 3 and divide the answer by 4, which is 18.

Answer:

FV= $3,672.07

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $3,200

Number of periods (n)= 4 years

Appreciation rate= 3.5% = 0.035

To calculate the price of the ring in four years, we need to use the following formula:

FV= PV*(1 + i)^n

FV= 3,200*(1.035^4)

FV= $3,672.07

Answer:

x = 6, z=88

Step-by-step explanation:

The angle 92 and z lies on a straight line.

Therefore,

[tex]z + 92 = 180 \\ z = 180 - 92 = 88[/tex]

Same goes for Angle Z and 5x+62.

[tex]z + 5x + 62 = 180 \\ 88 + 5x + 62 = 180 \\ 150 + 5x = 180 \\ 5x = 180 - 150 = 30 \\ x = 30 \div 5 = 6[/tex]

Answer:

0.9 of a Liter for the bottle's volume

0.18 L for each cut

180 mL    for each cup.

Step-by-step explanation:

60/100 * 1.5 = 0.6 * 1.5 = 0.90

There were 5 cups

The volume of the bottle was 0.9 liters

1 cup held 0.9 / 5 = 0.18 L

1 Liter = 1000 mL

0.18 L = 1000 *0.18 = 180 mL

Step-by-step explanation:

y-x=0.7

y=x+0.7, so lets plug in that into the expressions instead of y

1)

(y-x)=

x+0.7-x=

x+0.7+(-x)=

x+(-x)+0.7=

x-x+0.7=

0.7

2)

(x-(x+0.7))/((x+0.7)-x)=

(x-x+0.7)/(x+0.7-x)=

(x-x+0.7)/(x+0.7+(-x))=

(x-x+0.7)/(x+0.7+(-x))=

(x-x+0.7)/(x+(-x)+0.7)=

(x-x+0.7)/(x-x+0.7)=
