Lesson 1-4 (cont.)Translate each sentence into a mathematicalequation or inequality.1) Eight less than twice the sum of four and yis the same as 19.2(4 + y) - 8 = 192) Six more than x is more than twice thedifference of x and 7.x + 6 > 2(x -7)3) The quotient of m and 3 is six less than theproduct of 10 and m.m 3 = 10m -64) Five less than x is less than five less x.x -5 < 5 - xYou want to purchase apples and oranges for 20friends. Apples cost 30 cents and oranges cost 20cents. Write an expression for the total amountthat you would spend.Apple price = .30 Orange price = .20# of apples = n # of oranges = 20 - nTotal = .30n + .20(20 - n)Total = .30n + 4 - .20nTotal = .10n + 4Algebra 2 <strong>Slide</strong> <strong>Show</strong>: Teaching Made Easy As Pi, by Mike Mills and James Wenk © 2010
