Write an algebraic expression for each word phrase. 1) 9 less than a number w 9 less than a number w w – 9 w – 9 2) 3 increased by the difference of p and 5 3 increased by the difference of p and 5 3 + (p – 5) 3 + p – 5

Write an algebraic expression for each word phrase. 3) the sum of a number h and 88 minus 4 the sum of h and 88 minus 4 h + 88 – 4 h + 88 – 4 4) the quotient of a number f and 6 quotient of f and 6 f  6 f 6

5) Write a word phrase for the algebraic expression 9 – 3c. 9 minus the product of 3 and c 9 minus the product of 3 and c.

6) Write a word phrase for the algebraic expression 7 + 19b. 7 plus the product of 19 and b 7 plus the product of 19 and b.

7) Write a word problem that can be evaluated by the algebraic expression 27 + t, and evaluate the expression for t = 1.76. Possible Answer: Amed bought a new sweater for $27 plus sales tax t. If the tax was $1.76, what was the total cost of the sweater? 27 + t 27 + 1.76 = 28.76 Substitute 1.76 for t. The total cost of the sweater was $28.76.

8) Write a word problem that can be evaluated by the algebraic expression 43 – d, and evaluate the expression for d = 10.24. Possible Answer: Tina bought a new jacket for $43 minus a store credit. If the store credit was $10.24, what was the total cost of the jacket? 43 – d 43 – 10.24 = 32.76 Substitute 10.24 for t. The total cost of the jacket was $32.76.
