b is read " a is greater than b ”. From there we pretty much the number followed by " as many", Like "15 times as many" is a=15b. I considered parsing the polynomial as $ \ (x^8 - x^5) \ + \ (x^2 -x + 1) \ $.Restricting techniques to ones that would likely appear in junior high school and high school curricula, we can show that $ \ x^2 - x + 1 \ $ is never equal to zero since its discriminant is $ \ -3 \ $.So its value can never change sign; since it equals $ \ 1 \ $ for $ \ x \ = \ 0 \ $, it is always positive. If there are 76 boxes in a case, write an algebraic expression to show the total number of paper clips. Found inside – Page 80Examples: Write an algebraic expression for each phrase. 1) Eight more than a number is 20. More than mean plus a number = x Then: 8 + x = 20 2)5 times the ... - the answers to answer-helper.com Which algebraic expressions are polynomials, select those that apply Answers: 3 Get Other questions on the subject: Mathematics ... (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. Terms of an Algebraic Expression – Answers. answer choices . e.g. Top Answer. Explanation: We can represent a number in general by x. Halving a number means dividing it by two, so the expression that shows the half of a number is x 2, since you divide a number … The quotient of 10x 10 x and 3 3. Six less than p runs than Pirates scored less than some number of x and 7 is equal to 13 twice a number x is four The total of 5 and c of 7 and d decreased by 9 difference of w and 10 is 7 times a product of 5 and a number a number is … As long as you understand the basic terms and rules of algebra, evaluating an expression is a simple process. An algebraic expression is a mathematical phrase that may include numbers, variables and operators. An algebraic expression is described using its terms, and operations on the terms. On the other hand, 1 ≠ 2.5. an equation containing but one unknown quantity, and that quantity only in the first degree. If the number is, say, N, then “10 less than twice the number” is 2N - 10. The key word is difference, which tells us the operation is subtraction. The expressions a < b or a > b can be read from left to right or right to left, though in English we usually read from left to right Table 1.1.3. algebra. An algebraic sentence when written in equation form involves algebraic expressions (which contain variables such as letters in the alphabet), constants, and an equal symbol. Algebra 1a. Q. So, 12 less than 20 is 8 , because is 20−12 , 12 less than 12 is 0 , because it’s 12−12 , and so on. exponential expression. CHAPTER 4 ALGEBRAIC EXPRESSIONS 73 4:02 | Substitution Algebra involves the use of ‘pronumerals’ as well as numbers. An expression contains the combination of constants variables together with the arithmetic operators. Therefore, the algebraic expression is, Example 2. We need to be careful of the order in which the terms are subtracted since we have 10 less than a number. Tags: Question 13 . Wiki User Answered 2009-09-24 16:21:49. m - 12. When working in algebra, you will need to change words and phrases into some form of mathematical language. Four more than #b# is imply written as #b + 4# Here as the steps: 1 " a number x" → x. The variable in the third term is b. 'Less than or equal to' can also be expressed as at most, no more than, a maximum of, and not exceeding.

It consists of two expressions, one on each side of an 'equals' sign. Students often confuse an algebraic equation with equality, but they are two distinct terminologies. But in context, You are given a triangle such that one angle in a triangle is less than one half of the total angle measurement, therefore the angle must be less than 90 degrees.
