<h3>Operations on Algebraic Expressions: </h3>
- The three major components of an algebraic expression are variables, constants, and coefficients. Addition, subtraction, multiplication, and division are the four fundamental operations. We solve both difficult and straightforward equations using operations on algebraic expressions.
- There are three categories of algebraic expressions: monomial, binomial, and polynomial or multi-term expressions.
- These are the algebraic terms:
- Alphabetic letters alone or in combination with numbers or fractions are the variables.The numbers that are connected to the variables in a single term are called coefficients.
- Constants: Single integers or numbers that are typically connected to other terms through elementary operations.Examples include 8xyz, 25x+12y+9, 2yz23zy, and 3a+2b+5c.
Algebraic Expression Types
There are three different categories for algebraic expressions. As follows:
- Expressions with a monomial or single word. For instance, 4xy2, 3ab, 7p, 5xyz, etc., where 3,4,5,7 are the coefficients and x, y, z, a, b, p are the variables.
- Expressions with two terms or a binomial. For instance, 2xyx, pq5p2, etc.
- Multi-term or polynomial expressions. as in 2x+5y4, 2xy2+3y+1, etc.

Answer:
2) 4/3
Step-by-step explanation:
(4^-3 * 3^4 * 4^2)/(3^5 * 4^-2)
4^-3 * 3^4 * 4^2 = 4^-1 * 3^4
(4^-1 * 3^4)/(4^-2 * 3^5)
(3^4)/(3^5) = 1/(3^5-4)
(4^(-1))/(4^-2 * 3^(5-4)
(4^-1)/(4^-2 * 3)
4^(-1 - (-2)) / (3)
-1 - (-2) = 1
4/3
Answer:
Five touchdowns were made in the game
Step-by-step explanation:
Here, we want to know the number of touchdowns made during the game.
We proceed as follows;
Let the number of touch downs be x
So the total points earned through touchdowns is 6 * x = 6x
The number of scores is 10 times
Let the number of extra kick be y which means that the number of conversions will be (y-1)
So the total number of score times will be ;
x + y + y-1 = 10
x + 2y = 11 •••••••••(i)
Now let’s work with points
Touch down points = 6 * x = 6x
Points from extra kick = 1 * y = y
Points from 2-point conversions = 2(y-1) = 2y - 2
So;
6x + y + 2y -2 = 37
6x + 3y = 37 + 2
6x + 3y = 39
divide through by 3
2x + y = 13 •••••••(ii)
So now solve simultaneously
From ii, y = 13 - 2x
Put this into i
x + 2(13-2x) = 11
x + 26 - 4x = 11
x -4x = 11-26
-3x = -15
x = -15/-3
x = 5
There are five touchdowns in the game
Answer:
A health questionnaire is a list of questions about someone's health issued by underwriters before accepting a person as a risk.
In this case the survey focuses on occupational health related issues.
Step-by-step explanation:
A health questionnaire is a list of questions about someone's health issued by underwriters before accepting a person as a risk.
Failure to volunteer full information on a health questionnaire can result in coverage being voided during a claim.
If the health questionnaire reveals that you have been treated for a certain disease, such as cancer or heart disease, the insurer may add a rider to the policy that excludes the condition.
Furthermore, health surveys can shed light on the level of healthcare the population is being offered, as well as understand health insurance coverages given to the audience. In certain cases, health surveys can be focussed to understand specific diseases or disorders by conducting longitudinal surveys or frequent surveys so as to track patterns and trends, thus allowing the survey owner to make appropriate decisions accordingly. Health surveys are an effective method to collect data from a large population or a target group.
