Answer:
x=1/8
Step-by-step explanation:
First we need to isolate the variable. We can do that by subtracting 3 from each side. You then get: 24x-2=1. Then, to completely isolate it, add 2 to each side. We get 24x=3. Now divide 24 from each side to get only x. We get 3/24, which can be rewritten as 1/8.
A regular hexagon is inscribed in a circle with radius 9 cm. Find the area
Answer:
121.5sqrt(3)
Step-by-step explanation:
Ok, so all regular hexagons are made out of 6 equilateral triangles. If the hexagon is inscribed in the circle, the radius lines up with a side of one of the 6 equilateral triangles and you get 6 equilateral triangles with a side length of 9.
The formula for an equilateral triangle's area is (a/2)^2 * sqrt(3) where a = side length. That means we just plug in 9 to find the area of one of these six triangles. We get 20.25sqrt(3).
We multiply this by 6 (to find the sum of the areas of 6 equilateral triangles) and get 121.5sqrt(3)
The area of the hexagon will be 210.4 cm².
What is a hexagon?The definition of a hexagon in mathematics and geometry is a polygon with six straight sides that is closed in two dimensions.
Given, a circle with a radius of 9 cm. which have a regular hexagon whose all corner touch the circle. If we draw a radius of a circle at the corner of the hexagon. then we get six equilateral triangles.
A regular hexagon is 6 equilateral triangles of side r and area
Area of triangle = (r/2)(√3r/2)
so the total area is
A(hex ) = (6/4) √3r² = 3√3(r²)/2
r = 9m so
A = 210.4m²
Hence the Area of the given hexagon is 210.4 square meters.

Rewrite this phrase using algebraic symbols eight times a number is decreased by 12
Answer:36
Step-by-step explanation:
Which relationship is an inverse variation?
x 2 4 6 8
f(x) 12 6 4 3
x 1 2 3 4
f(x) –1 –2 –3 –4
x 1 2 3 4
f(x) 4 16 36 64
x 2 4 6 8
f(x) 6 12 18 24
The relation that is an inverse variation is the one in the first table:
x 2 4 6 8
f(x) 12 6 4 3
Which relation is an inverse variation?An inverse variation between two variables x and y can be written as follows:
y = k/x
Where k is a constant.
Notice that x is on the denominator, so, as x increases, the value of y decreases.
Now, for example if we use the values of the first table:
x 2 4 6 8
f(x) 12 6 4 3
The first pair is (2, 12)
Replacing that in the inverse variation formula we get:
12 = k/2
12*2 = k
24 = k
For the second pair (4, 6) we will get:
6 = k/4
6*4 = k
24 = k
And so on for all the pairs. If the variation is inverse, you should always get the same value of k (like in this case).
So this is the correct answer.

Fit-quest charges a one-time registration fee of $50 plus $5 per fitness class. Fitnasium charges no registration fee, but charges $8 per fitness class. For how many fitness classes does Fitnasium cost less than or the same as Fit-quest?
Answer:
16
Step-by-step explanation:
50 + (5×16) 8×16
50 + 80 128
130. 128.
if she goes to gitnasium 1 more time then it eould be more than Fit-Quest.
16 of the fitness classes do Fitnasium cost less than or the same as Fit-quest.
What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have been given that Fit-quest charges a one-time registration fee of $50 plus $5 per fitness class. Fitnasium charges no registration fee, but charges $8 per fitness class.
Let the number of classes would be x
⇒ 50 + (5x) = 8x
Rearrange the terms of x in the above equation,
⇒ 8x - 5x = 50
⇒ 3x = 50
⇒ x = 50/3
Apply the division operation,
⇒ x = 16
Therefore, 16 of the fitness classes do Fitnasium cost less than or the same as Fit-quest.
