Help please!!!!!!!!!!!!!!!!!

Answer:

Step-by-step explanation:

27x + 12y = -216

8x - 12y = -64

35x = -280

x= -8

2(-8) - 3y = -16

-16 - 3y = -16

-3y = 0

y = 0

(-8, 0)

Answer:

Scientific notation is used to write very large or very small numbers using less digits. ... See how scientists use this notation to describe astronomical distances, such as the distance between planets, or microscopic distances, such as the length of a blood cell.

Step-by-step explanation:

These are just a few examples of how scientific notation is used in the real world. Its versatility allows scientists, engineers, mathematicians, and professionals from various disciplines to work with numbers efficiently and communicate effectively across different scales.

Scientific notation, also known as exponential notation, is widely used in various fields to express very large or very small numbers in a more convenient and concise format. Here are some examples of how scientific notation is used in the real world:

Astronomy: Scientific notation is essential in astronomy to represent the vast distances between celestial objects. For instance, the distance between the Earth and the Sun is approximately 93 million miles or 1.496 × 10²kilometers.

Physics: Scientists often use scientific notation to express the values of physical constants, such as the speed of light (2.998 × 10^8 meters per second) or the Planck constant (6.62607015 × 10^-34 joule-seconds).

Chemistry: Scientific notation is commonly used in chemistry to express the magnitude of extremely small or large quantities of substances. For example, Avogadro's number, which represents the number of atoms or molecules in one mole of a substance, is approximately 6.022 × 10².

Medicine: In medical and biological sciences, scientific notation is employed to represent quantities such as cell counts, enzyme activity, or concentrations of substances. It allows scientists and healthcare professionals to work with numbers that span a wide range, from tiny quantities to large-scale measurements.

Finance and Economics: Scientific notation is useful in financial and economic calculations, especially when dealing with large numbers such as national debt, gross domestic product (GDP), or company revenues. It simplifies the representation and manipulation of these values.

Engineering: In various engineering disciplines, scientific notation is used to express measurements and quantities, such as distances, weights, electrical currents, and voltages. It enables engineers to work with both very large and very small values encountered in their calculations and designs.

Computer Science: Scientific notation is employed in computer science to represent large or small numbers in computer programming. It is particularly useful when dealing with values that exceed the capacity of standard data types or when expressing very small probabilities or error values.

Step-by-step explanation:

Answer:

She bought 19 chicken wings

Step-by-step explanation:

first, find how much 1 chicken wings cost

$39.1 / 23= $1.70 (1 chicken wings cost = $1.70)

32.30/ 1.70 = 19

She bought 19 chicken wings

Hope it helps

If my answer helps you, please give me a brainliest! thanks.

If Aaliyah spent $32.30, she brought 19 chicken wings.

One of the four fundamental operations in mathematics is division, along with addition, subtraction, and multiplication. The splitting of a large group into smaller groups so that each group contains an equal number of items is a straightforward definition of division. It is a mathematical process used for equitable grouping and distribution.

Aaliyah bought 23 chicken wings for $39.10.

Hence, as the price of each chicken wings is same, the price of each  chicken wings  will be=  $39.10÷23 = $ 1.70

She spent $32.30 in buying chicken wings.

So,  The number of chicken wings, she got = $32.30/$1.70 = 19.

Hence,  if Aaliyah spent $32.30, she brought 19 chicken wings.

Answer:

54.8 is the correct answer

Answer:

principal (p) = 2400

Amount (A) =2646

time (t) = 2 years

Interest = A-p

           =2646-2400=246

T = I * 100/(P*T)

  = 246*100/(2400 *2) = 5.125%

Step-by-step explanation:

The rate of interest will be 5.125% for the given data.

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.

Given that the sum of rs 2400 compounded to rs 2646 in 2 years. The compound interest will be calculated as,

principal (p) = 2400

Amount (A) =2646

time (t) = 2 years

Interest = A-p

=2646-2400=246

T = I x  100/(P x T)

T = ( 246 x 100) / (2400  x 2)

T = 5.125%

Hence, the interest rate will be %5.125.

Answer:

mid point (x,y) = M (18, 24)

let J (- 4, - 2) be ( x1, y1)

     L(a,b) be (x2,y2)

using midpoint formula

(x,y) = [(x1+x2)/2, (y1 + y2)/2]

or, (18, 24) = [(-4+a)/2, (-2+b)/2]

comparing corresponding element we get

18 = (-4+a)/2                 24 =(-2+b)/2

or 36 = -4+ a            or 48 = -2 +b

Answer:

-12

Step-by-step explanation:

(f·g)(-4) = f(g(-4))

g(-4) = 3(-4)+6

g(-4) = -12 + 6

g(-4) = -6

f(g(-4)) = f(-6) = 3(-6) +6

f(g(-4)) = -18 + 6

f(g(-4)) = -12

1/3x+3

It is asking for 1/3 of x which is 1/3x

three more essentially means add 3

So 1/3x+3 is the answer

The expression is,

y = 1/3x+3

Where, y is number write with the help of x

And, x is a number.

Here,

We have to write an expression for a number that is three more than one third the value of x.

What is Number system?

A system of writing to express the number is called Number system.

Now,

x represents a number.

Let a number y which is written as, three more than one third the value of x.

One third of x = 1/3 x

Then, more than 3 means to add 3, we get

y = 1/3 x + 3

Hence, The expression is,

y = 1/3x+3

Where, y is number write with the help of x

And, x is a number.

Answer:

Step-by-step explanation:

​1/2 (2x+8)=3x+8−x

Use the distributive property to multiply 1/2=0.5 by 2x+8.

1/2 x 2x+1/2x8=3x+8-x

Cancel out 2 and 2.

x+1/2 ×8=3x+8−x

Multiply 1/2 =0.5 and 8 to get  8/2=4.

x+8/2=3x+8−x

Divide 8 by 2 to get 4.

x+4=3x+8−x

Combine 3x and −x to get 2x.

x+4=2x+8

Subtract 2x from both sides.

x+4−2x=8

Combine x and −2x to get −x.

−x+4=8

Subtract 4 from both side

−x=4

Multiply both sides by −1.
