Use elimination to solve and match each system of equations to the correct solution
9x+4y=-72
2x-3y=-16
Answer:
Step-by-step explanation:
27x + 12y = -216
8x - 12y = -64
35x = -280
x= -8
2(-8) - 3y = -16
-16 - 3y = -16

how is scientific notation used in the real world
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.

What value of x with make the equation below true?
1/2 (2x + 8) = 3x + 8 - x
Please help
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.
x=−4
If x represents a number then write an expression for a number that is three more than one third the value of x
Answer:
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.

An object is moving at a speed of 11 yards every 6 months. Express this speed in centimeters per hour. Round your answer to the nearest hundredth.
Answer:
its c
i took the quiz
Step-by-step explanation:
The speed in centimeters per hour is 0.2328 centimeters per hour.
Given,
An object is moving at a speed of 11 yards every 6 months.
We need to find this speed in centimeters per hour.
How many centimeters in one yard?1 yard = 91.44 centimeters.
We have,
11 yards every 6 months
11 yard = 6 months
1 month = 30 days
1 day = 24 hours
30 days = 30 x 24 hours
30 days = 720 hours
1 month = 720 hours
6 months = 6 x 720 hours
6 months = 4320 hours
11 yards = 4320 hours
1 yard = 91.44 cm
11 x 91.44 cm = 4320 hours
1005.84 cm = 4320 hours
So,
we will find how many cm per hour.
if 1005.84 cm = 4320 hours then,
Dividing both sides by 4320.
1005.84/ 4320 cm = 4320/4320 hours
0.2328 cm = 1 hour
Rounding to the nearest hundredth.
0.23 cm = 1 hour
Thus the speed in centimeters per hour is 0.2328 centimeters per hour.

Find (f•g)(-4) if f(x)= 3x +6 and g(x)=3x+6.
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

Answer:
B
Step-by-step explanation:
The sections of the parallel roads split by the transversals are in proportion, that is
[tex]\frac{350}{300}[/tex] = [tex]\frac{first}{1650}[/tex] ( cross- multiply )
300 first = 577500 ( divide both sides by 300 )
first = 1925 ft
