We are used to seeing the words, plus, sum, difference, minus, product Look for the words of and and to find the numbers.
Lauren has dimes and nickels in her purse. The next lesson in this unit is on simplifying algebraic expressions. This is seven years less than your age now.
Seven less than means seven subtracted from your present age. The good news is that these very same words that we use to write numerical expressions are going to be used to write algebra expressions.
Eight more than means eight added to your present age. They tell us the operation is addition. Geoffrey has dimes and quarters in his pocket. Let w represent the width of the window.
They tell us the operation is subtraction. Think of "of" meaning to multiply when you are working with fractions. Division is not commutative, so you must pay close attention to the order in which you write the expression.
You are probably very used to translating words into numerical expressions. Algebraic Expressions and Key Words for Addition As, you can see from the red, bold words, the key words for addition are: Remember that subtraction is not commutative, so the order in which write the digits does matter!
How old were you seven years ago? The number of dimes is seven less than six times the number of quarters. A quotient is the answer to a division problem. This will help you to easily translate the expression.
Let l represent the length of the rectangle. The key words are: We will study this in more depth as we get into writing and solving algebraic word problems. Solution Write a phrase about the height. Because we are multiplying 5 times the sum, we need parentheses around the sum of m and n.
The number of dimes is 2 less than 5 times the number of quarters. Write an expression for the number of dimes. The length of a rectangle is 5 inches less than the width. What age is eight more years than your age now? Did you add 8 to your present age?
This skill will come in handy when working with word problems or real life situations. One of the most important things to remember is to look for key words and to make sure that your expression matches the context of the word problem.
Let n represent the number of nickels. Key words for each operation are indicated in bold. As you begin to work with algebraic expressions more, you will see word problems that require you to use more than one operation.
Translate the given word phrase into an algebraic expression: Solution Write a phrase about the number of dimes. Of is the tricky word. Play close attention to the order in which it is written.
Pay close attention to the "key words" that represent mathematical operations. The height of a rectangular window is 6 inches less than the width.Aug 07, · Translate the given word phrase into an algebraic expression: (a) the difference of 47 and 41 (b) the quotient of 5x and 2 exercise Translate the given word phrase into an algebraic expression: (a) the sum of 17 and 19 (b) the product of 7 and x.
The difference between a numerical expression and an algebra expression is that we will be using variables when writing an algebraic expression. Instead of "8 plus 9" (with two given numbers), you would see, "a number plus 9".
Convert the word phrase to the algebraic expression Learn with flashcards, games, and more — for free. Write a word phrase for the algebraic expression 3x The difference of three times and number x and seven. The difference of seven and three times a number x.
Write a word phrase for the Algebraic expression 3x - 7 My answer is the difference of 3 times a number x and 7 URGENT 8th Grade Math Write a word phrase for the algebraic expression 3x 3x - 6 "less than" means subtract from what follows the "less than" This table shows some very common word sentences and their translation into an algebra equation.Download
