the estimated time to lay the shingles and underlayment

The Estimation cost of the shingles chosen for the roof.

Estimation cost is the process of predicting how much a project or task will cost. It is used to help make decisions about the feasibility of the project and to plan for its budget. Estimation cost is based on past experiences, the current market and expected future conditions. The accuracy of an estimate can be improved by gathering detailed information about the project and its components. This information can include the cost of materials, labor and time needed to complete the project. Estimation cost is an important part of project management and is used in combination with other project management tools and methods such as scheduling, budgeting and risk management.

The fourth arrow is used to represent inequality x>3.2

A number system is defined as a system of writing to express numbers.

Number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

All the positive numbers are represented on the right side of the origin and all the negative numbers are represented on the left side of the origin, with a definite scale.

Here x>3.2 which means that values of x are greater than 3.2 so we use Open circle with right arrow.

Hence, the fourth arrow is used to represent inequality x>3.2

B= -43t +272 and Q=-59t+320 equations for each situation, in terms of t, and at 3 hours Brody and Qasim are the same distance from the stadium.

Two or more expressions with an Equal sign is called as Equation.

Given,

At noon, Brody is 272 miles away from the stadium

B represent Brody's distance, in miles, away from the stadium tt hours after noon.

Brody is driving along the highway at a speed of 43 miles per hour

Qasim is 320 miles away from the stadium

Qasim is driving at speed of 59 miles per hour.

Q represent Qasim's distance, in miles, away from the stadium t hours after noon

B= -43t +272

Q=-59t+320

-43t+272=-59t+320

-43t+59t=320-272

16t=48

t=3

Hence, B= -43t +272 and Q=-59t+320 equations for each situation, in terms of t, and at 3 hours Brody and Qasim are the same distance from the stadium.

The cost to replace all the windows on all the building in the United States is $7,200,000.

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

Given that the cost to replace a window is $3 per window. IT should be noted that when there are 2,400,000 windows, the cost to replace all the windows on all the building in the United States will be:

= Cost of replacement × Total window

= $3 × 2,400,000

[tex]y=-\dfrac{1}{3}x+5[/tex]

Step-by-step explanation:

A line's slope is defined as rise over run.

The rise and run between the coordinates (0, 5) and (3, 4) is:

rise: -1

run: 3

Therefore, the slope of the line is -1/3. This is what x is multiplied by.

Next, to find what is added to x, find where the line crosses the y-axis. IN this case, that point is when y = 5, so in the second blank put 5.

Variable y exponente.

Step-by-step explanation:

En una expresión algebraica la reducción de términos semejantes se da entre los términos de igual variable o incógnita y exponente.

Por ejemplo:

3x² + 5x²

se pueden reducir pues tienen la misma variable x y el mismo exponente 2, su resultado se genera solo sumando, restando, los coeficientes, en este caso 3 y 5

3x² + 5x² = 8x²

En el caso:

3y² + 5x²

No se puede reducir pues la variable o incógnita no son iguales:

x≠y

En el caso:

3x² + 5x³

No se pueden reducir pues su exponente no es igual.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

-2x + 8 = -2x + 8

-2 makes the equation equal.

Option A is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 6 is an equation.

We have,

-2x + 8 = __x + 8

The equation has infinitely many solutions when both sides of the equation are equal.

Now,

-2x + 8 = -2x + 8 is equal on both sides.

Thus,

-2x + 8 = -2x + 8

-2 makes the equation equal.
