Find x: 3x − 14 + 6 − 4 − 2x = 12
Answers
The required value of the x in the given algebraic expression is 10.
To find the value of x in the given equation, you need to solve for x. Let's simplify the equation step by step:
3x - 14 + 6 - 4 - 2x = 12
Combine like terms:
(3x - 2x) + (6 - 4) = 12
x + 2 = 12
Now, isolate x by subtracting 2 from both sides:
x = 12 - 2
x = 10
So, the value of x is 10.

The expression used is the circumference of a circle which is 80π
What are the circumference and diameter of a circle?
The circumference of a circle is the distance around the circle which is 2πr.
The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.
Given, A circular skating rink has a radius of 40 feet.
∴ The expression can be used to find the circumference of the
skating rink is 2π(40) = 80π feet.

They are all multiplied by each other
r = radius
we know our radius is 40
and...
so we would use this expression
3.14 x 40 x 2
As a added bonus ill solve it for you :P
3.14 x 40 x 2 = 251.2
The circumference of this ice skating rink is 251.2 feet

Which of the following statements is correct about the two system equations?
A) The value of x for System B will be 4 less than the value of x for System A because the coefficient of x in the first equation of System B is 4 less than the coefficient of x in the first equation of System A.
B) They will have the same solution because the first equations of both the systems have the same graph.
C) They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 4 times the second equation of System A.
D) The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding -4 to the first equation of System A and the second equations are identical.

6x + y = 2
-x - y = -3
System B:
2x - 3y = -10
-x-y = -3
Solve:
System A:
6x + y = 2
y = 2 - 6x
-x - (2-6x) = -3
-x - 2 + 6x = -3
5x = -3 + 2
5x = -1
x = -1/5
y = 2 - 6(-1/5)
y = 2 + 6/5
y = 2 + 1.2
y = 3.2 System A: x = -1/5 or -0.2 ; y = 3 1/5 or 3.2
System B:
2x - 3y = -10
2x = -10 + 3y
x = -5 + 1.5y
-x - y = -3
-(-5 + 1.5y) -y = -3
5 - 1.5y - y = -3
-2.5y = -3 - 5
-2.5y = -8
y = 3.2
x = -5 + 1.5(3.2)
x = -5 + 4.8
x = -0.2 System B: x = -0.2 ; y = 3.2
B) They will have the same solution because the first equations of both the systems have the same graph.

Answer:
18 meters
Step-by-step explanation:
"Perimeter" is all 4 sides added together, right?
Since it's a square, all four sides are equal, so the problem looks like this:
s + s + s + s = 72 where s = side length
Before doing any math, can you think of a number that you could add to itself 4 times and get 72? If not, you get to do some algebra:
s + s + s + s = 72 reduces to:
4s = 72 Then solve for s:
s = 72/4 = 18 m
Check your work by seeing if 4 x 18 = 72. It does, so the answer is correct.
