Explanation:
Let "x" represent the "unknown number".
→ "One-half" of a number , decreased by "6" ;
→ is written as: "1/2 of "x" , minus "6" .
Note that: " 1/2 of x " = " [tex]\frac{1}{2}[/tex] * x " = " [tex]\frac{1}{2}[/tex] x " .
Then, we subtract "6" ; from that value; to write the expression:

Marvin counts six $5 bills. write each value that he counts. what pattern do you see in the one digits of the values he counts?
When counting $5 bills, the values are $5, $10, $15, $20, $25, $30 with a pattern in the one digits of 5, 0, 5, 0, 5, 0. This demonstrates the pattern of addition with multiples of five.
Explanation:Marvin is counting $5 bills, hence each time he counts a bill the total value increases by $5. The values Marvin counts are $5, $10, $15, $20, $25, $30.
The one digits in these values form a pattern, specifically, they are 5, 0, 5, 0, 5, 0.
This pattern repeats every two counts: a 5 followed by a 0. This is because adding 5 to a multiple of 10 results in a number ending in 5, and adding another 5 results in another multiple of 10, which always ends in 0.

A figure is translated rotated or reflected describe its image
Final answer:
Transformations in mathematics involve translating, rotating, or reflecting figures, resulting in images that maintain their shape but may change position, orientation, or both. Examples include translations that shift figures, rotations that pivot them around a point, and reflections that create mirror images.
Explanation:
When a figure is translated, rotated, or reflected, its image undergoes specific transformations. In a translation, every point of the figure moves the same distance in the same direction, resulting in a figure that maintains its shape and orientation but changes its position. A rotation involves turning the figure around a fixed point known as the center of rotation, changing the direction of the figure while preserving its shape and size. Finally, a reflection is akin to looking into a mirror, where the figure is flipped over a line known as the axis of reflection, creating a mirror image that maintains the shape and size of the original figure but reverses its orientation.
These transformations can be visually represented and understood using diagrams, such as those involving ray diagrams for reflections. For example, in the reflection of an object in a mirror, light rays hitting the mirror generate new rays that appear to originate from a point behind the mirror, creating a virtual image. This conceptual understanding helps to explain how images are formed through various transformations, highlighting the precision and predictability of geometric operations.

The sum of the square of two negative numbers is 74. The difference is 24. determine the two numbers
The required negative numbers are -5 and -7.
What is a quadratic equation?The quadratic equation is defined as a function containing the highest power of a variable is two.
Let the required negative numbers be x and y.
The sum of the square of two negative numbers is 74.
(x)² + (y )² = 74
x² + y² = 74
(x)² - (y)² = 24
y² - x² = 24
y² = x² + 24
Substitute the value of y² = x² + 24 in the equation x² + y² = 74,
x² + 24 + x² = 74
2x² = 74 - 24
2x² = 50
x² = 25
x = √25
x = ±5
x = 5, -5
Take the negative value as per the question.
Substitute the value of x = -5 in the equation y² = x² + 24,
y² = (-5)² + 24
y² = 25 + 24
y² = 49
y = √49
y = ±7
y = - 7
Therefore, the required negative numbers are -5 and -7.

Final answer:
The problem is solved by converting the given conditions into a system of equations, which is then solved to find the two negative numbers. The numbers obtained, -3 and -27, satisfy both given conditions.
Explanation:
The question provided is a mathematical problem involving the determination of two negative numbers given that their squares sum to 74 and their difference is 24. Let's denote the smaller number as x and the larger number as y. The given conditions can be represented by two equations: [tex]x^2 + y^2 = 74[/tex] and y - x = 24.
To find the values of x and y, we solve these equations simultaneously. First, use the second equation to express y in terms of x:
y = x + 24
Then, substitute this expression for y into the first equation:
[tex]x^2 + (x + 24)^2 = 74[/tex]
This simplifies to a quadratic equation in x, which can be solved to find the value of x, and subsequently, y can be determined using the expression
y = x + 24.
After solving the quadratic equation, you find that the two negative numbers are -3 and -27, satisfying both the sum of their squares equaling 74 and their difference being 24.

The given mathematical expression is solved by simplifying within parentheses, performing multiplication, and understanding the absolute value concept, leading to a final answer of 70.
Explanation:The given mathematical expression is |4-8(3-12)| - |5-11|. To solve this, we first need to simplify the expressions within the absolute value bars, following the order of operations (PEMDAS/BODMAS).
Step 1: Simplify inside the parentheses3-12 = -9. So, the expression now is |4-8(-9)| - |5-11|.
Step 2: Multiply8 times -9 equals -72. Substituting this, we get |4 - (-72)| - |5-11|, which simplifies to |4 + 72| - |5-11|.
Step 3: Simplify the absolute values4 + 72 equals 76, so |76| is just 76 because absolute values ensure a positive outcome. Next, 5-11 equals -6, so |5-11| is |-6|, which is 6. Therefore, you have 76 - 6.
Step 4: SubtractLastly, subtracting 6 from 76 gives 70. So, the final answer to the given expression is 70.

in a recent survey of middle school students about pizza toppings it was found that 25 students liked pepperoni pizza 31 like banana peppers pizza and 5 liked both pepperoni and banana peppers on their Pizza if 66 students where surveyed how many students do not like banana peppers on their Pizza
Using the principle of inclusion-exclusion, it was determined that out of 66 surveyed students, 15 do not like banana peppers on their pizza.
The number of students who do not like banana peppers on their pizza can be calculated as follows:
Students who like pepperoni pizza only = 25 - 5 = 20
Students who like banana peppers pizza only = 31 - 5 = 26
Students who do not like banana peppers = Total students surveyed - Students who like banana peppers - Students who like only pepperoni = 66 - 31 - 20 = 15 students
