What comes first in an equation a variable or a number?
A variable comes after the number 2n+5n=7n
How would you write the algebraic expression for one fourth the difference of a number and 7?
The algebraic expression for one fourth the difference of a number and 7 can be written as (1/4)(x - 7), where x represents the unknown number. This expression first calculates the difference between the number and 7 by subtracting 7 from the number (x - 7), then finds one fourth of that difference by multiplying the result by 1/4.
How do you write an expression in quadratic form?
Write an expression consisting of up to three terms:One term in which the key variable is squared,one term with a multiple of the variable, anda constant.The first of these MUST be present. The three terms must be added or subtracted.
What is the degree for a number without a variable?
anything without a variable is to the first power. To find the degree, you look at what the power of the number is and that will be the degree. The degree is the number of times your coefficient is a factor. Since the exponent is one, so is the degree. Ex. 2x squared = 2nd degree
What comes first independent or dependent variable?
Independent variable
How do you evaluate a math expression?
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
What is the algebraic expression for 8 more than half a number?
The algebraic expression for "8 more than half a number" can be represented as ( \frac{x}{2} + 8 ), where ( x ) represents the unknown number. This expression first calculates half of the number by dividing it by 2, then adds 8 to the result.
What is algebraic expression for sum of two numbers is 20?
let x = first number let y = second number x + y =20
When subtracting an algebraic equation which comes first a variable or the constant?
It does not matter.
When writing an algebraic expression do you write the coefficients with the highest value first example 7x plus 3y or is 3y plus 7x also correct?
It is correct to write it any way you like. However, when dealing with equations it is usual to give the dependent variable (usually y) first; if it is unknown which variable is the dependent one (or for any general expression), they are usually written in alphabetical order.
Who is the first discoverer for algebraic expression?
It was the Persian mathematician Al Khwarizmi in about 820AD who first conceived the idea of algebra.
How do you factor the expression two m squared minus eight?
2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----
How do you change algebraic expression into mathematical phrase?
first of all you need to simplify it in the form of a+b
When doing algebraic expression do you put the letter first?
Well if your question is about individual terms then the answer is no. A term in a polynomial always has coefficients listed before the variable (i.e. 3x). But if you're asking about terms within an expression, then it doesn't matter. It would be correct to write y=x-5 or y=(-5)+x.
How do you find base of an unknown number in number system?
You first determine the algebraic numerical equilibrium ( algorythm ) and divide it by the sum of the true algebraic expression (X)-(X=?>y^Zy<~=X)Answer. Basic Pythagoras Theorem co-tangent w/equilibrium.
What comes first in an equation a variable or a number?
A variable comes after the number 2n+5n=7n
Rules in operations in algebraic expression?
Parenthesis, Exponents, Multiplication or Division(whichever come first from left to right*), Addition or Subtraction *
