rearrange the equation 12n + 3px = 7px
From factoring, the given equation can be rearranged as [tex]x=\frac{3n}{p}[/tex].
Factoring
In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization. One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.
For solving this question, the given equation should be rewritten using the variables n and p in different sides. After that, you should factor out a common term.
[tex]12n + 3px = 7px\\ \\ 12n=7px-3px\\ \\ 12n=4px\\ \\ x=\frac{12n}{4p} =\frac{4*3n}{4p}=\frac{3n}{p}\\ \\ x=\frac{3n}{p}[/tex]

What is the value of x in the diagram
Answer:
51°
Step-by-step explanation:
the given angle of 102° is the arc angle between the 2 segment end points on the circle arc.
and this arc angle is always a seen from the center of the circle.
by moving the reference point back (to the other side of the circle) to the circle arc that angle is cut in half.
you could move that point to anywhere on the arc of the circle outside of the 2 endpoints, and the angle stays always the same.
FYI - now, if you move that point into the top half-circle between the 2 end points, the perspective flips around, and that angle becomes half of the 360-102 = 258° arc angle.
What is the formula for the nth term of the sequence 2,4,8,16,32
Answer:
Below in bold.
Step-by-step explanation:
4/2 = 2
8/4 = 2
Each term is obtained by multiplying the previous one by 2.
This is a geometric sequence with common ratio r = 2
the nth term
= a1r^(n-1) where a1 = the first term
= 2(2)^(n-1).
[tex] a_{n} = 2_{n}[/tex]
Step-by-step explanation:
[tex]a_{1} = 2[/tex]
[tex]d = a_{2} - a_{1}[/tex]
[tex] = 4 - 2 = > 2[/tex]
Getting the nth term
[tex]a_{n} = a_{1} + (n - 1)d[/tex]
[tex] a_{n} = 2 + (n - 1)2[/tex]
[tex] a_{n} = 2 + (2n - 2)[/tex]
[tex]a_{n} = 2 + 2n - 2[/tex]
[tex] a_{n} = 2n[/tex]

Hope this helps :)
The term best describes point X is option A. Centroid.
What is the centroid of a triangle and its coordinates?The point of intersection of a triangle's medians is its centroid (the lines joining each vertex with the midpoint of the opposite side).
here, we have,
If the surface is plane triangle approximately and mass is uniformly distributed, then its center of mass will lie on the centroid of that triangle.
we have,
If the triangle has its vertices as (x1, y1) (x2,y2) (x3,y3)
then the coordinates of the centroid of that triangle is given by:
(x, y ) = (x1+x2+x3/3 , y1+y2+y3/3 )
Hence, The term best describes point X is option A. Centroid.

Answer:
360 degrees
Step-by-step explanation:
The sum of the INTERior angles of a pentagon equal
(n-2)(180) = 540
each angle is then 540/5 = 108
each is a supplementary angle to the exterior angle
so EACH exterior angle is 180 - 108 = 72

angle associated with the arc? Use 3.14 for It. Give your answer in degrees and radians (approximate to two
decimals and exact).
The measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a length of an arc of a circle of radius 7 is approximately 10.99 cm.
The radius r = 7 cm
The arc length l = 10.99 cm
We know,
l = rθ
θ is the central angle.
θ = l/r = 10.99/7 = 1.57 radians
To convert 1.57 radians into the degree multiply it by 180/π
θ = 89.95 degree
Thus, the measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.

If f(x)=8-10x and g(x) =5x +4, what is the value of (fog)(-2)?
Answer:
68
Step-by-step explanation:
Any function is evaluated by putting the argument value where the variable is, then doing the arithmetic. When the argument is another function value, that function value is evaluated first.
__
f∘gThe "o" in (fog) is a stand-in for the "ring operator" (∘) which is the operator used to signify a composition. A composition is evaluated right-to-left. That means (f∘g)(x) ≡ f(g(x)). The value of g(x) is found first, and is operated on by the function f.
Writing the composition in the form f(g(x)) lets you identify the layers of parentheses. As with any expression evaluation, the Order of Operations applies. It tells you to evaluate the expression in the innermost parentheses and work your way out.
g(-2)To evaluate (f∘g)(-2) = f(g(-2)), we must first evaluate g(-2). That is ...
g(x) = 5x +4
g(-2) = 5(-2) +4 = -10 +4 = -6 . . . . . put -2 where x is, do the math
f(g(-2))Now that we know g(-2) = -6, we know this expression is ...
f(-6) = 8 -10(-6) = 8 +60 = 68 . . . . . substitute for x in 8-10x
Then the value we're looking for is ...
(f∘g)(-2) = 68
