The measure of an angle being equal to itself is an example of the Reflexive Property, which states that any quantity is equal to itself.
Explanation:The statement "The measure of an angle is equal to itself" is true because of the Reflexive Property. This property states that any quantity is equal to itself, which is a fundamental idea in mathematics and logic. In the context of geometry and angles, it means that an angle is always equal to its measure. So, if θ represents the measure of an angle, then we could say θ = θ, which demonstrates the Reflexive Property.
The other properties listed—the Property of Equality, Symmetric, and Transitive—are also important in the realms of algebra and geometry but do not directly apply to the fact that an entity is equal to itself. Instead, these properties involve the relationship between different entities or the equality between them derived from other equalities.

Chad has 6 fewer sandwiches than Sarah.chad had 7 sandwiches. how many sandwiches did Sarah made?
Answer:
13
Step-by-step explanation:
If Chad had 7 sandwiches and that was 6 fewer than the amount Sarah has then Sarah made 6 sandwiches. The working is as follows :
Chad = 7 sandwiches (6 fewer than Sarah)
Sarah = ?
Sarah = 7 + 6 = 13 sandwiches.
In order for Chad to have eaten that many sandwiches, Sarah would have had to have made 13 sandwiches.
Sarah made x number of sandwiches and Chad ate 7 out of it.
The 7 that Chad ate remained 6 sandwiches out of the total that Sarah made.
The number of sandwiches Sarah made is therefore:
= Number that Chad ate + Number that was left
= 7 + 6
= 13 sandwiches
In conclusion, Sarah made 13 sandwiches

Find the answer to the problem -5/6 + (-1/12)
To solve -5/6 + (-1/12), convert both to have a common denominator of 12, resulting in -10/12 + (-1/12). Add the numerators to get -11/12. The sum of two negative fractions maintains a negative sign.
Explanation:To find the answer to the problem -5/6 + (-1/12), we need to add the two fractions. When adding fractions with different denominators, we first find a common denominator. In this case, the common denominator for 6 and 12 is 12. We then convert each fraction to an equivalent fraction with this common denominator.
For the first fraction -5/6, we multiply both the numerator and the denominator by 2 to get -10/12. The second fraction is already with a denominator of 12, so we keep it as -1/12. Now, we add the numerators while keeping the denominator the same:
-10/12 + -1/12 = -11/12. The sum of the two fractions is -11/12, which is already in simplest form.
This example demonstrates that when two negative numbers add, the answer has a −ve sign, and the numerators are simply added together while the denominator remains the same.

For direct variation, represented by y = kx, we replace y and x with the provided values. We solve for k to get 36. The direct variation equation is y = 36x.
Explanation:In the case of direct variation, the equation is usually presented in the form of y = kx, where k is the constant of variation. To write an equation to represent the direct variation between x and y with the given values, we will begin by replacing y and x in our equation with the given values 12 and 1/3 respectively.
That gives us 12 = k(1/3). By solving for k, we obtain k = 12 / (1/3) = 36. Thus, the equation representing the direct variation between x and y is y = 36x.

3. Your car gets 30 mpg on the highway. If gas costs $4.20 per
gallon, how much does it cost to drive your car per mile?
Answer:
It costs $0.14 to drive your car for one mile.
Hope this helps :)
To calculate the cost of driving per mile, the price of gasoline ($4.2) should be divided by the car's fuel efficiency (30 mpg). This results in a cost of $0.14 per mile.
Explanation:To find out how much it costs to drive per mile, we need to divide the cost of one gallon of gas by the number of miles that can be driven with that gallon. In this case, the cost of gasoline is $4.20 per gallon and the mileage of the car is 30 miles per gallon.
First, identify the cost of gas per gallon and the car's fuel efficiency (miles per gallon). Here, the cost is $4.2 and efficiency is 30 mpg.Next, you should divide the cost per gallon by the miles per gallon. Therefore, $4.20 ÷ 30 = $0.14, which represent the cost per mile.
So, in this scenario, it costs approximately $0.14 to drive your car for one mile on the highway.

A 20” Square is being copied at 25%. What are the dimensions of the New square after being copied?
Answer:
5"
Step-by-step explanation:
You are copying a square of side 20 inches into a smaller version of it that is exactly 25% of the original size.
Notice that 25% can be written in fraction form as: [tex]\frac{25}{100} = \frac{1}{4}[/tex]
This gives us a clue about how to reduce the original dimension: "multiply it by [tex]\frac{1}{4}[/tex], which is the same as divide it by 4:
[tex]20" * \frac{1}{4} = \frac{20"}{4} = 5"[/tex]
Find the slope of the segment with the endpoints (1, − 1/n ) and ( n/m , − 1/m ).
(y - yo) = m.(x - xo)
Let's go
(-1/n - (-1/m)) = s.(1 - n/m)
(-1/n + 1/m) = s.(1 - n/m)
(-m+n)/mn = s.(m - n)/m
If we multiply both sides by m
(-m + n)/n = s.(m - n)
If we take the (-1) from the left side we have
(-1.(m - n))/n = s.(m - n)
And if we divide both sides by (m - n)
-1/n = s
So our slope is -1/n

y=3x-5 and y=1/2x+5 Write your answer as an ordered pair, (x,y).
use the substitution method
y=3x-5
y= 1/2x+5
3x-5= 1/2x+5
move -5 to the other side
sign changes from -5 to +5
3x-5+5= 1/2x+5+5
3x= 1/2x+10
move 1/2x to the other
3x-1/2x= 1/2x-1/12x+10
3x-1/2x= 10
find the common denominator for 3x
pretend that there is a 1 for 3x. 3x/1. The common denominator is 2. Mutiply the fraction by 2
3x(2)/1(2)
= 6x/2
6x/2-1/2x= 10
5/2x= 10
mutiply both sides by 2/5
5/2x(2/5)= 10(2/5)
Cross out 5 and 10, divide by 5 . Then becomes 2*2= 4
x= 4
find y by using the substitution method
y=3x-5
y= 3(4)-5

Answer: (4,7)
To find the ordered pair (x, y) that satisfies the given equations y=3x-5 and y=1/2x+5, we can solve the system of equations simultaneously. The ordered pair is (4, 7).
Explanation:To find the ordered pair (x, y) that satisfies the given equations y=3x-5 and y=1/2x+5, we need to solve the system of equations simultaneously. By setting the two expressions for y equal to each other, we can find the x-coordinate. Substituting this value back into either equation will give us the y-coordinate.
Let's set 3x-5 equal to 1/2x+5:
3x-5 = 1/2x+5
Multiplying through by 2 to eliminate the fraction:
6x-10=x+10
Combining like terms:
5x=20
Dividing both sides by 5:
x=4
Substituting this value of x into y=3x-5:
y=3(4)-5
y=12-5
y=7
Therefore, the ordered pair (x, y) is (4, 7).
