What is 96-8c=20-12
Answer:
c = 11
Step-by-step explanation:
96 - 8c = 20 - 12 , that is
96 - 8c = 8 ( subtract 96 from both sides )
- 8c = - 88 ( divide both sides by - 8 )
c = 11

A rectangular playground is to be fenced in using a wall on one side and 210 meters of fencing for the other three sides. The area A(z) in square
meters of the playground is a function of the length z in meters of the side parallel to the wall.
Write an expression for A(z)
The function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)
How to write a function of the length z in meters of the side parallel to the wall?The given parameters are:
Perimeter = 210 meters
Let the length parallel to the wall be represented as z and the width be x
So, the perimeter of the fence is
P = 2x + z
This gives
210 = 2x + z
Make x the subject
x = 1/2(210 - z)
The area of the wall is calculated as
A = xz
So, we have
A = 1/2(210 - z) * z
This gives
A = z/2(210 - z)
Rewrite as
A(z) = z/2(210 - z)
Hence, the function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)

At Dapper Dave's annual end-of-season sale, every necktie in the shop gets marked down. Dillon purchased 6 neckties during the sale. Each necktie cost $5 less than its full price. He paid a total of $162. What is the cost of each necktie at full price?
$32 is the cost of each necktie at full price.
Given that
At Dapper Dave's annual end-of-season sale, every necktie in the shop gets marked down.
Dillon purchased 6 neckties during the sale. Each necktie cost $5 less than its full price.
He paid a total of $162.
To find
What is the cost of each necktie at full price ?
So, according to the question
we have,
On that end-of-season sale
Total purchased neckties = 6
Discount on each neckties = $5
Amount paid by him = $162
Let's assume the full price of one neckties is $x.
So,
The price of one neckties after discount = x - 5.
So the price of one neckties after discount = 6(x-5)
He paid $162 for 6 neckties,
So we can say that
the price of one neckties after discount = $162
So,
6(x-5) = 162
x-5 = 162/6
x-5 = 27
x = 27+5
x = 32
The cost of each necktie at full price is $32.

explain why the statement x < 3 or > 5 cannot be written 5 < x < 3
Answer:
This formula has no values, it is a false inequality. X can not be greater than 5, and less than 3.
Step-by-step explanation:
x < 3 or x > 5
This means, x is less than 3, but greater than 5.
Technically, you would write this as 5 < x < 3, however, this is a false inequality, and does not work.
∠A and \angle B∠B are vertical angles. If m\angle A=(5x+5)^{\circ}∠A=(5x+5)
∘
and m\angle B=(6x-8)^{\circ}∠B=(6x−8)
∘
, then find the value of x.
Each of the pairs of opposite angles made by two intersecting lines are called a pair of vertical angles. The value of x is 13.
What are vertical angles?Each of the pairs of opposite angles made by two intersecting lines are called a pair of vertical angles.
Given that ∠A and ∠B are vertical angles. Therefore, the measure of the two of the given angle will be equal to each other. Thus, we can write the measure of the two angles as,
∠A = ∠B
(5x + 5)° = (6x - 8)°
5x + 5 = 6x - 8
Bring the like terms on the same side of the equation,
5 + 8 = 6x - 5x
13 = x
x = 13
Hence, the value of x is 13.

What solution value satisfies the compound inequality 4 < 3x∕2 + 1 < 7?
Question 12 options:
A)
x = 0
B)
x = 4
C)
x = 3
D)
x = 6
Answer:
C) x = 3
Step-by-step explanation:
To find the solution value that satisfies the inequality 4 < 3x∕2 + 1 < 7, you must plug every x value into the x and see which one works.
Plug 0 into x
4 < 3(0)∕2 + 1 < 7
4 < 0∕2 + 1 < 7
4 < 0 + 1 < 7
Combine like terms
4 < 1 < 7
This is false, 1 is not greater than 4.
Plug 4 into x
4 < 3(4)∕2 + 1 < 7
4 < 12∕2 + 1 < 7
4 < 6 + 1 < 7
Combine like terms
4 < 7 < 7
This is false, 7 is not less than 7.
Plug 3 into x.
4 < 3(3)∕2 + 1 < 7
4 < 9∕2 + 1 < 7
4 < 4.5 + 1 < 7
Combine like terms
4 < 5.5 < 7
This is true, 5.5 is greater than 4 and less than 7.
Plug 6 into x.
4 < 3(6)∕2 + 1 < 7
4 < 18∕2 + 1 < 7
4 < 9 + 1 < 7
Combine like terms
4 < 10 < 7
This is false, 10 is not less than 7.
C) x = 3 is the only true solution that works, so that is your answer.

Use the diagram to find the following measures
A) triangle angle sum equation
B) value of x = ———- degrees
Answer:
x = 71°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°.
The measure of two angles out of three is given, we will use the following equation to find the value of the missing angle:
82 + 27 + x = 180 add like terms
109 + x = 180 subtract 109 from both sides
x = 71

The value of the circle is 20 while the triangle is 35
How to determine the values of each shape?From the figure, we have
Three circles and Two triangles
Such that:
Three circles = 60
One circle and Two triangles = 90
Represent the circle with x and the triangle with y
So, we have
3x = 60
x + 2y = 90
The above forms a system of linear equations
Divide 3x = 60 by 3
x = 20
Substitute x = 20 in x + 2y = 90
20 + 2y = 90
This gives
y = 35
So, we have
Circle = 20
Triangle = 35
Hence, the values of the shapes are 20 and 35, respectively

Temperature is a physical quantity that expresses the hotness of matter or radiation. The heat increases an objects temperature.
What is temperature?
Temperature is a physical quantity that expresses the hotness of matter or radiation.
The temperature of the object increases due to the absorbed part of the heat. An object decreases its temperature by releasing energy in the form of heat to its surroundings. And an object increases its temperature by gaining energy in the form of heat from its surroundings.
So the temperature changes according to the heat of the surrounding.
