Write each phrase as an algebraic expression then simplify. Let x represent the number.?
1. The difference between 8 and the number = (8 - x) Therefore the algebraic expression for a number decreased by the difference between eight and the number = x - (8 -x) Removing the brackets remembering that minus minus = plus = x - 8 + x = 2x - 8 factor out the common factor "2" = 2(x - 4) 2. Negative 2 times the number = -2x The product of 6 and a number = 6x Therefore the expression that represents the difference between the product of six and a number and negative two times a number is 6x - (-2x) (Once again minus minus = plus) = 6x + 2x = 8x
Write the phrase as an algebraic expression. “a number less 15”.?
Let x be a number then "a number less 15" is written as "x - 15".
Anybody good at writing phrases into algebraic expressions?
1. one more ball than is on the playground 2. three more cookies than are in the jar 3. twelve fewer questions than were on the first test 4. eight dollars more than the shirt costs 5. three times as many drinks on the tray 6. five dollars less than Yumi's pay 7. the english class has half as many students as the math class 8. 1/3 of emily's age 9. ten times the minutes spent exercising 10.Spencer bought 3 books of stamps and mailed a package. It cost $4.50 to mail the package. Define a variable and write an expression to represent the total amount he spent at the post office.
How can I write a verbal expression of an algebraic expression?
If the questioner finds Claire Germond's answer to be helpful, then it strikes me as a rather silly sort of question which would only be asked by someone who does not even understand the algebra. On the other hand, it would be an interesting question if it were in a sense which is the reverse of what we call a "word problem". I.e., what is a word problem which would be solved by evaluating this expression (or solving this equation)? It is even a relevant question for a teacher who is trying to compose exercises which can be used to teach the use of a particular mathematical techniques. Unfortunately, I don't think the reverse-word-problem version of the question admits all that simple an answer. The type of math matters - e.g., logic, set theory, algebra, linear equations, calculus, etc. (Yes, even a calculus problem can lead to an algebraic expression.) The kinds of word problems you compose must deal with real-world objects and phenomena which can be modeled using the relevant math. It takes some creativity. On the other hand, we have all seen enough such word problems that it is not all that hard to generalize, changing the details as necessary to make the word problems interesting.
Change the word phrase to an algebraic expression. Use "x" to represent the number?
8 - (2/5)x make sure its 2/5 times x or 2 times x over 5 and not 2 over 5x http://www.algebrahouse.com
Need help with algebraic expression please?
1) Straightforward. P multiplied by 3 is is P times 3, P*3, or 3*P, or just 3P 2) Word order is a little different than math order. "N less than 7" means "7 made less by N" means "7 minus N" means 7-N 3) is just like 2) backwards -- ( S - 10 ) is "S made less by 10" is "10 less than S" or "ten less than some number" 4) ( AB ) can be spoken as "the product of A and B". ( AB + 2 ) can be spoken as "the product of A and B made greater by 2" or "2 more than the product of A and B" for 5 through 7, I'll define "N" as my variable 5) "the sum of 4 and a number" means "a number made greater by 4" means ( N + 4 ) 6) "three made greater by a number" is ( 3 + N ) 7) "12 less than a number" means "a number made smaller by twelve" means ( N - 12 ) for 8 through 10, I'll still use N. I'll also use X. N for the number I can plug in, X for the answer to the question. I think there's a typo in 8), so I'm not going to address it 9) "the answer is 48 made less by some number" X = 48 - N 10) "the answer is the product of some number of clothes and the cost of each piece" X = N * $32.95 To answer 10), you have to already know that the total cost is equal to the product of the number of items bought and the price for each item. And, you have to simply assume that either the question is about the cost before taxes, or that the given price already includes tax, or that tax simply doesn't matter. Sometimes math classes want you to assume stupid things.
Write an algebraic expression for the given quaintly let X represent the unknown value.?
