Algebraic expression definition

Mathematics
2 answers:
Hunter-Best [27]3 years ago
7 0

Answer:

A mathematical equation or phrase that includes numbers, variables, and operators.

Step-by-step explanation:

Examples of numbers: 1, 5, 60, 100

Examples of variables: a, x, y

Examples of operators, +, -, x, /

Any mathematical equation with all 3 of the given examples is called an algebraic expression.

For example:

1 + 21 is not an algebraic expression, because although it has both numbers and operators, it does not have a variable.

x + 2 is an algebraic expression, because it has all 3 of the components listed above.

Hope I helped :)

Answer:

The ordered pairs (3 , 6) , (5 , 10) show a proportional relationship ⇒ last answer

Step-by-step explanation:

* Lets explain how to sole the problem

- Proportional relationship describes a simple relation between

 two variables

- In direct proportion if one variable increases, then the other variable

 increases and if one variable decreases, then the other variable

 decreases

- In inverse proportion if one variable increases, then the other variable

 decreases and if one variable decreases, then the other variable

 increases

- The ratio between the two variables is always constant

- Ex: If x and y are in direct proportion, then x = ky, where k

 is constant

 If x and y in inverse proportion, then x = k/y, where k is constant

* Lets solve the problem

# Last table

∵ x = 3 and y = 6

∴ x/y = 3/6 = 1/2

∵ x = 5 and y = 10

∴ x/y = 5/10 = 1/2

∵ 1/2 is constant

∵ x/y = constant

∴ x and y are proportion

* The ordered pairs (3 , 6) , (5 , 10) show a proportional relationship

How to solve 4n-40=7(-2n+2)
Damm [24]

4n-40=7(-2n+2)

4n-40=-14n+14

subtract -4n from both sides

-40 = -18n +14

subtract -14 from both sides

-54=-18n

divide both sides by -18


3 = n
