Tricky Ones! 5 plus x 5 + x add 5 and x 5 + x the sum of 5 and x 5 + x 5 increased by x 5 + x 5 more than x x + 5 5 is more than x 5 > x Algebra I by James Wenk © 2003 published by TEACHINGpoint as part of the Expert Systems for Teachers Series

Tricky Ones! 5 minus x 5 - x 5 less x 5 - x the difference of 5 and x 5 decreased by x 5 - x 5 less than x x - 5 5 subtracted from x x - 5 5 is less than x 5 < x Algebra I by James Wenk © 2003 published by TEACHINGpoint as part of the Expert Systems for Teachers Series

1) six less than twice a number x 2) five times the sum of y and 4 Translate each phrase into a mathematical expression. 1) six less than twice a number x 2) five times the sum of y and 4 3) twice the difference of m and 3 4) the quotient of 7 and a number x less 2 5) the difference of 6 and k divided by 9 6) 4 times the sum of 12 and y 2x - 6 5(y + 4) 2(m - 3) 7 x - 2 (6 - k) 9 4(12 + y) Algebra I by James Wenk © 2003 published by TEACHINGpoint as part of the Expert Systems for Teachers Series

1) Eight less than twice the sum of four and y is the same as 19. 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 = 10m - 6 x - 5 < 5 - x Algebra I by James Wenk © 2003 published by TEACHINGpoint as part of the Expert Systems for Teachers Series
