To solve the problem, an algebraic equation is set using the given conditions. After solving it, it's established that Nate has 28 one-dollar bills and 21 five-dollar bills.

Let's solve the problem in two steps. First, we already know the total sum of money Nate has, which is $267, and the value of his eleven $10 bills, which is $110. So, we subtract $110 from $267, leaving $157 to be divided among the $5 and $1 bills.

Next, we assign variables to the unknowns. Let's call the no of $1 bills 'x' and no of $5 bills ''x-7'. A $5 statement is worth five $1 bills so that we can rewrite 'x-7' as '5(x-7)'. Setting up the equation 5(x - 7) + x = 157 and solving for x gives us 28.

The problem-solving strategy here is using a system of equations to solve a money problem. So Nate has 28 one-dollar bills and 21 five-dollar bills (28-7).

no decimals?

are u asking a factor or something that makes up a whole number or.....?

A factor of a number divides the number. For example, 2, 3, and 4 are all factors of 12. Similarly, we say that 12 is a multiple of 2, or a multiple of 3, because one can multiply 2 by a whole number to get 12. A number is a multiple of its factors.

Given points (5,102) (4,74) and (-2,-10)

We frame 3 equations using the given points

[tex]y=ax^2+bx+c[/tex]

Plug in (5,102)

[tex]102=a(5)^2+b(5)+c[/tex]

102 = 25a +5b + c -------> first equation

Plug in (4,74)

[tex]74=a(4)^2+b(4)+c[/tex]

74 = 16a +4b + c----> second equation

Plug in  (-2,-10)

[tex]-10=a(-2)^2+b(-2)+c[/tex]

-10 = 4a -2b + c -----> third equation

Now we use the three equation and solve for a,b,c

Use first and second equation and subtract it

102 = 25a +5b + c

-74 = -16a -4b - c

----------------------------------

28 = 9a + b  --------------> fourth equation

Subtract third equation from first equation

102 = 25a +5b + c

10  = -4a +2b - c

----------------------------------

112 = 21a + 7b --------------> fifth equation

Use fourth and fifth equation

28 = 9a + b

112 = 21a + 7b

Multiply the fourth equation by -7

-196= -63a -7b

112 = 21a + 7b

-----------------------

-84 = -42a

Divide by -42 on both sides

a= 2

Plug in the value of a=2 in fourth equation

28 = 9a + b

28 = 9(2) + b

28 = 18 + b ( subtract 18 from both sides)

b = 10

Plug in the values in third equation and find out c

-10 = 4a -2b + c

-10= 4(2) -2(10)+c

-10 = -12 + c

c= 2

We got a=2, b=10  and c=2

So equation becomes [tex]y=2x^2+10x+2[/tex]

The proposed definition of a regular polygon as having all angles of the same measure is incomplete because it omits the criterion of all sides being equilateral. Hence, some irregular polygons could fit this definition, making it not entirely valid.

The definition of a regular polygon as “a polygon with all angles the same measure” is not completely valid.

A more precise definition of a regular polygon is a polygon that is both equiangular (all angles have the same measure) and equilateral (all sides have the same length).

While all regular polygons have angles of equal measure, the definition provided is incomplete as it does not include the requirement that all sides must also be of the same length.

For example, consider an isosceles triangle (a triangle with two sides of equal length).

This triangle has two angles of the same measure and one that is different. B

ased on the provided definition, one might incorrectly classify this as a regular polygon, even though it is not.

Thus, the correct answer is C. No, because some polygons that are irregular fit this definition.

Final answer:

The definition for a regular polygon as 'a polygon with all angles the same measure' is not fully accurate because it omits the requirement for all sides to be of equal length.

The correct answer to the question is C. No, because some polygons that are irregular fit this definition.

Explanation:

The definition of a regular polygon that states it is “a polygon with all angles the same measure” is not entirely valid. While it's true that a regular polygon does have equal angles, the definition is incomplete without the inclusion of another important characteristic: all sides must be of equal length.

Therefore, the correct answer to the question is C. No, because some polygons that are irregular fit this definition.

An irregular polygon can also have equal angles but different side lengths, so the definition given would incorrectly include some irregular polygons.

When thinking about a regular polygon, it's essential to consider both equal angles and equal side lengths, just as when thinking about a triangle, it includes a three-sided figure lying on a plane with three angles adding up to 180 degrees.

y=3x-7 that's the answer

The equation of a line that is parallel to y=3x−2 and passes through the point (5,8) is y = 3x - 7, since parallel lines share the same slope and the y-intercept was calculated using the given point.

To write the equation of a line that is parallel to a given line and passing through a certain point, you need to know that parallel lines have the same slope. The line y=3x−2 has a slope of 3. So the line parallel to it will also have a slope of 3.

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. Since we already have the slope, we only need to find the y-intercept, b. We do this by plugging the given point coordinates (5, 8) into the equation and solving for b:

8 = 3*5 + b, which gives b = 8 - 15 = -7.

Therefore, the equation of the line parallel to y=3x−2 and passing through the point (5,8) is y = 3x - 7.

Answer:

There are 5000 cattle

Step-by-step explanation:

Based on your given information there should be 5000 cattleN=100×50

The simplified expression is 22m + 42, and the number of cattle on the Lazy Circle Double Bar for Square Ranch depends on the value of m that represents the relevant metric for cattle population.

To simplify the expression 7(2m + 6) + 8m, we first distribute the 7 across the terms inside the parentheses:

7(2m + 6) = 7 * 2m + 7 * 6 = 14m + 42

Then, we combine like terms by adding the 14m and 8m:

14m + 8m = 22m

Now, we substitute this result back into the original expression:

7(2m + 6) + 8m = 14m + 42 + 8m = 22m + 42

So, the simplified expression is 22m + 42.

To find the number of cattle on the Lazy Circle Double Bar for Square Ranch, we need to know the value of m, which represents the number of cattle per unit area or another relevant metric. Once we know the value of m, we can substitute it into the simplified expression 22m + 42 to find the total number of cattle.

For instance, if m = 100, then the expression becomes 22(100) + 42 = 2200 + 42 = 2242 cattle on the ranch.

In summary, the simplified expression is 22m + 42, and the number of cattle on the Lazy Circle Double Bar for Square Ranch depends on the value of m that represents the relevant metric for cattle population.

Melissa has completed 85% of the bike course by riding 51 out of 60 miles. This was calculated by dividing the distance ridden by the total distance and multiplying by 100.

To find out what percentage of the bike course Melissa has ridden, we need to divide the distance she has ridden by the total distance of the course and then multiply by 100 to get the percentage. Melissa has ridden 51 miles of the 60 miles long course. Therefore, the percentage of the course she has ridden is calculated as follows:

When we perform this calculation, we get:

(51 / 60) * 100 = 85%

So, Melissa has ridden 85% of the bike course.

The area cannot be calculated without knowing the shape of the object these measurements belong to or how these measurements are arranged. Different shapes require different calculations for area.

The question is asking for the area of an object given certain dimensions, but without knowing what type of object these measurements belong to or how these measurements are arranged, it's impossible to accurately calculate an area. Area calculation differs based on the shape of the object. For instance, the area of a square or rectangle is calculated by multiplying its length by its width, the area of a circle is calculated using pi times the radius squared, and the area of a triangle is calculated by multiplying the base by the height and then dividing by two. Each of these calculations uses different dimensions in different ways. We would need more information to solve this problem.

The area of the object will be 63 square inches. Then the correct option is C.

It addresses the various forms' sizes, shapes, regions, and densities in both two and three dimensions.

In the event that w = 7 inches, x = 6 inches, y = 8 inches, z = 5 inches, and u = 3 inches, v = 4 inches.

The figure displays all of the dimensions.

The combination of two rectangles and one triangle then makes up the geometry's area.

Area is equal to the sum of the areas of the three triangles, the rectangles 1 and 2.

Area = 5 x 8 + 4 x 5 + (1/2) x 3 x 2

Area is 40 + 20 + 3.

Area = 63 square inches

Then, choice C is the right one.

x is equal to 27.

In order to find the value of x, you have to use the average formula and solve for the missing variable. The mean formula is all of the numbers added together divided by the number of inputs.

(inputs added)/(number of inputs) = Average

(2 + 7 + x)/3 = 12 ----> Multiply by 3

9 + x = 36 ----> Subtract 9

x = 27

To find the value of x when the average of 2, 7, and x is 12, you set up and solve the equation (2 + 7 + x) / 3 = 12. After simplifying, you will find that x equals 27.

The question asks us to find the value of x when the average (arithmetic mean) of the numbers 2, 7, and x is 12. To find the value of x, we use the formula for the arithmetic mean, which for three numbers is (number1 + number2 + number3) / 3 = average. So, we set up the equation: (2 + 7 + x) / 3 = 12.

First, we multiply both sides of the equation by 3 to eliminate the fraction:
2 + 7 + x = 36. Next, we add the known values on the left side: 9 + x = 36. Finally, to find x, we subtract 9 from both sides of the equation: x = 36 - 9, which simplifies to x = 27. Therefore, the value of x is 27.

ensure all fractions have the same denominator

we require - [tex]\frac{1}{4}[/tex] = - [tex]\frac{4}{16}[/tex]

thus - [tex]\frac{7}{16}[/tex] - [tex]\frac{4}{16}[/tex] - [tex]\frac{5}{16}[/tex]

take out a common factor [tex]\frac{1}{16}[/tex]
