Read Carefully! 5 more than x x + 5 5 is more than x 5 > x 5 less x The keyword(s) determine which math symbol to use 5 more than x x + 5 5 is more than x 5 > x 5 less x 5 - x 5 less than x x - 5 5 is less than x 5 < x

Examples 1) Eight less than twice the sum of four and y Translate each sentence into a mathematical equation or inequality. 1) Eight less than twice the sum of four and y is the same as 19. 2) Six more than x is more than twice the difference of x and 7. 3) The quotient of m and 3 is six less than the product of 10 and m. 4) Five less than x is less than five less x. 2(4 + y) - 8 = 19 x + 6 > 2(x - 7) (m ÷ 3) = (10  m) - 6 x - 5 < 5 - x
