Exercise 9 Page 443

We are given a word sentence and we want to write an equation that it represents. The productof a number s and 14 is 49. Every equation has an equals sign and values or expressions on either side of this symbol. Key phrases, such as is, is equal to, and equals tell us about the placement of the equals sign. The productof a number s and 14 is 49. ⇕ The productof a number s and 14 = 49. On the left-hand side, we have the phrase The product of a number s and 14. These words tell us that s is a variable symbol and that the operation that will be used in our inequality is the multiplication. This is because of the words the product. The productof a number s and 14 = 49. ⇕ s * 14 = 49. On the right-hand side, we have the constant 49. If we put these sides together, we have a complete equality. The product of a number s and 14 is 49. ⇕ s * 14 = 49
