**Translating Words to Mathese**Algebra 1**MATHESE (the language of math)**Write all the terms that imply these operations. Addition Subtraction Multiplication Division**Is there a difference?**eight more than sixversussix more than eight four less than five versusfive less than four product of two and four versus product of four and two quotient of six and three versus quotient of three and six Fifteen divided by three versus three divided by fifteen**Using a Verbal Model**• Ask yourself what you need to know to solve the problem. • Assign labels to each part of the verbal model. • Use the labels to write an algebraic model based on the verbal model. • Solve the algebraic model and answer the original question. • Check that your answer is reasonable.**Example Using a Verbal Model**The terrific math club is selling Pi Day shirts at $15 each. The club wants to raise $300 for a math field trip.**Problem #1**five more than n**Problem #2**Eleven less than a number**Problem #3**• Five less than six times a number**Problem #4**• Jeremy’s sister is 6 years older than Jeremy. Write an expression for the age of Jeremy’s sister.**Problem #5**• 7 divided by the sum of x and 5**Problem #6**Fifty divided by two times a number**Problem #7**y added to the product of 7 and m**Problem #8**Twelve less than a number is thirty.**Problem #9**Four times a number increased by seven**Problem #10**y subtracted from twice a number**Problem #11**Four more than half a number**Problem #12**Fifteen less than the product of 8 and r**Problem #13**• Andrea’s brother is 14 years younger than Andrea. Write an expression for the age of Andrea’s brother.**Problem #14**The difference of eighty-one and a number**Problem #15**Twice the sum of five and a number**Problem #16**Triple the sum of five and a number x**Problem #17**Fifteen less than eight times a number**Problem #18**Write a variable expression for “15 divided by the sum of x and 4.”**Problem #19**• Write a variable expression for “15 multiplied by the sum of x and 4.”**Problem #20**• Write a variable expression for “30 divided by the difference of t and 8.”**On Your Own**Write your own expression in words and then in mathematical symbols.**AssignmentPg. 35: 1-22**Translating word problems. 1. What operation does the word difference indicate? 2. translate the verbal phrase, "the difference of 7 and a number n" into an algebraic expression 3. Is order important in the expression in Exercise 2? 4. Describe how to use a verbal model to solve a problem. Write as an algebraic expression. 5. Eleven decreased by the quantity four times a number x. 6. Four increased by the quantity eleven times a number x. 7. four times the quantity of a number x minus eleven. 8. four times a number x decreased by eleven. 9. a number x increased by ten is 24. 10. The product of seven and a number y is 42. 12. Twenty divided by a number n is less than or equal to two. 12. Ten more than a number x is greater than fourteen. 13. Nine more than a number 14. one-half multiplied by a number 15. Three more than half of a number 16. a number increased by seven. 17. quotient of a number and two tenths 18. product of four and a number 19. two cubed divided by a number 20. difference of ten and a number 21. five squared minus a number 22. twenty-nine decreased by a number**AssignmentPg. 35: 23-48**Translating word problems. • Nine is greater than three times a number s • Twenty-five is the quotient of a number y and 3.5 • The product of 14 and a number x is one. • Nine less than the product of ten and a number d is eleven • Three times the quantity two less than a number x is ten. • Five decreased by eight is four times y. • Twenty-three less than the difference of thirty-eight and a number n is less than eight • A number t increased by the sum of seven and the square of another number s is ten. • Five less than the difference of twenty and a number x is greater than or equal to ten • Fourteen plus the product of twelve and a number is less than or equal to fifty.**AssignmentPg. 35: 23-48**Translating word problems. • Nine plus the quotient of a number b and ten is greater than or equal to eleven. • Seventy divided by the product of seven and a number p is equal to one. • A number q is equal to or greater than one hundred. • A number x squared plus forty-four is equal to the number x to the fourth power times three. • The quotient of thirty-five and a number t is less than or equal to seven. • Fifty multiplied by the quantity twenty divided by a number n is greater than or equal to two hundred fifty.**Translating word problems.**• Ben’s hourly wage b at his after school job is $1.50 less than Eileen’s hourly wage e. • The distance s to school is 1/5 mile more than the distance c to the Community Center swimming pool. • The length c of the Colorado River is three times the length r of the Connecticut River, plus 229 miles. • Pi () is the quotient of the circumference C and the diameter d of a circle. • The volume V of a cube with a side length s is less than or equal to thirty minus three. • The product of $25 and the number m of club memberships is greater than or equal to $500. • The perimeter P of a square is equal to four times the difference of a number s and two. • The simple interest earned on a principal of three hundred dollars at an annual interest rate of x percent is less than or equal to seventy-two dollars. • The area A of a trapezoid is equal to one half times the sum of seven and nine, times a number h plus seven. • The square of the length c of the hypotenuse of a right triangle is equal to four squared plus three squared.
