X-4/4=8 Solve this variable on this equation
Answer:
x=9
Step-by-step explanation:
divide 4 by 4 to get 1
x-1=8
9-1=8
Hey there!
x - 4/4 = 8
x - 1 = 8
ADD 1 to BOTH SIDES
x - 1 + 1 = 8 + 1
CANCEL out: -1 + 1 because it give you 0
KEEP: 8 + 1 because it give you the x-value
NEW EQUATION: x = 8 + 1
SIMPLIFY IT!
x = 9
Therefore, your answer is: x = 9
Good luck on your assignment & enjoy your day!

What is the simplest form of
2(3x-2y) + 3(x-3y)
Answer:
9x - 13y
Step-by-step explanation:
2(3x - 2y) + 3(x - 3y)
Use distributive law a(b + c) = ab + ac
⇒ 2·3x - 2·2y + 3·x - 3·3y
⇒ 6x - 4y + 3x - 9y
Gather like terms:
⇒ 6x + 3x - 4y - 9y

A movie director needs to purchase 325 films. The film has a volume of 965 in', and the density of each film is 7.6 g/in?. Each film can be purchased for $0.34 per kilogram. What is the cost of the films?
The volume of the films is the amount of film in the case
The cost of the films is $810.41
How to determine the cost of the films?The given paramerers are:
Volume = 965 cubic inchesDensity = 7.6 gram per cubic inchesThe mass of the films is calculated as:
Mass = Density * Volume
This gives
Mass = 7.6 * 965 g
Evaluate
Mass = 7334 g
Express as kg
Mass = 7.334 kg
The unit cost is:
Unit cost = $0.34 per kilogram
The number of films is
n = 325
So, the total cost
Total = 325 * 0.34 * 7.334
Evaluate
Total = 810.41
Hence, the cost of the films is $810.41

answer fast its a test q.
based on the statement is true?
Answer:
the right answer is F (exterior angle of triangle is equal to its sum of opposite interior angle of a traingle)
Answer: W = 40 degrees.
Step-by-step explanation: When you're finding a missing interior angle, all you need is the angle measurements of the other two angles. According to the picture, we have two 70's given, which both add up to 140. All the interior angles of a triangle need to add up to 180, and we have 140 so far. That's where the missing angle comes in. When you subtract 140 from 180, you get 40, which is your missing angle.
Let me know if this is right! :)

The average temperature on day 2 was -54.5.
What is Average?This is usually calculated with the sum of the numbers divided by how many numbers are present.
The average temperature on day 2 = -83-26 /2 = -54.5The difference of the average high temperature and the average low temperature for all four days include the following:Day one = -82-(-24) = -58
Day two = -83-(-26) = -57

There are _____ congruent triangles in a regular hexagon.
Find the perimeter.
Find the radius of this hexagon.
Answer:
There are 6 congruent triangles in a regular hexagon.
The triangles are equilateral (all sides are equal in length).
Using side length of equilateral triangle formula:
[tex]\sf x=\sqrt{\dfrac{4}{3}h^2}[/tex]
where x is the side length and h is the height
[tex]\sf \implies x=\sqrt{\dfrac{4}{3}\cdot 6^2}[/tex]
[tex]\sf \implies x=\sqrt{48}[/tex]
[tex]\sf \implies x=4\sqrt{3} \ units[/tex]
Therefore, perimeter = 6 × 4√3 = 24√3 units
Radius = side length of triangle = 4√3 units

3.245, 3.678, 3.3, 2.499, 2.9, 3.206, 2.081
Answer:
2.987
Step-by-step explanation:
The mean is calculated by dividing the sum of the terms by the # of terms.
For this problem, add all of the terms together:
3.245 + 3.678 + 3.3 + 2.499 + 2.9 + 3.206 + 2.081 = 20.909
Now, divide the product by the number of terms there are. There are 7 terms.
20.909 ÷ 7 = 2.987
The amount of a radioactive substance remaining after t years is given by the function f(t) = m(0.5)", where m is the
initial mass and h is the half-life in years. Cobalt-60 has a half-life of about 5.3 years. Which equation gives the
mass of a 50 mg Cobalt-60 sample remaining after 10 years, and approximately how many milligrams remain?
Using an exponential function, it is found that the equation is:
[tex]f(1.8868) = 60(0.5)^{1.8868}[/tex]
Which means that approximately 16.22 mg remain.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, the equation is:
[tex]f(h) = m(0.5)^h[/tex]
We work with a 50 mg Cobalt-60 sample, hence m = 60, and considering a half-life of 5.3 years, in 10 years we have h = 10/5.3 = 1.8868. Hence the equation is:
[tex]f(1.8868) = 60(0.5)^{1.8868} = 16.22[/tex]
Approximately 16.22 mg remain.

What is the total cost of a new car that has a price of $24,000 and a sales tax rate of 9%?
Answer:
26,160.00
Step-by-step explanation:
24,000 + 9% = 26,160.00
Have a wonderful day! Dream a good dream of good people. :)
Answer:
The answer is
→ $26,160
Step-by-step explanation:
In this problem, it says that the total cost of the new car is the price of $24,000 plus a sales tax of 9%. For the problem, it's obvious to use addition, because when you buy something, most of the time they add taxes.
So,
24,000
+ 9%

What is the difference between a metric and a norm?
Answer:
A norm and a metric are two different things. .
Step-by-step explanation:
The norm is measuring the size of something, and the metric is measuring the distance between two things. A metric can be defined on any set . It is simply a function which assigns a distance (i.e. a non-negative real number) to any two elements .
The major difference between the matric and norms is that metric is a unit of measurement that measures the distance between two objects. The size of a single thing is measured by a norm.
What is measurement?It is defined as the numerical quantity that gives an idea about an object's size, length, width, and many more. It can be used to compare two objects.
The major difference between metrics and norms is as follows:
A metric is a unit of measurement that measures the distance between two objects. The size of a single thing is measured by a norm.Metrics may be expressed on almost anything, however, a norm can only be defined on vector spaces but since the definition of a norm requires that the things measured by the norm be added and scaled.Thus, the major difference between the matric and norms is that metric is a unit of measurement that measures the distance between two objects. The size of a single thing is measured by a norm.

Answer:
A ≈ 8.6 ft²
Step-by-step explanation:
the area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] × 7 × 3 × sin55°
= [tex]\frac{1}{2}[/tex] × 21 × sin55°
