Presentation on theme: "_ + plus minus times divide add subtract multiply quotient"— Presentation transcript:

1 Objective - To translate English words and phrases into mathematical symbols and expressions.
_ + plus minus times divide add subtract multiply quotient increased by decreased by product sum diminished by …of... total difference twice ( 2) less more than added to less than subtracted from

2 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 added to x x + 5

3 Tricky Ones! 5 minus x 5 - x 5 less x 5 - x the difference of 5 and x 5 - x 5 decreased by x 5 - x 5 less than x x - 5 5 subtracted from x x - 5

4 3) 20 decreased by a number t 4) 6 added to the product of 11 and m
Translate each phrase into a mathematical expression. 1) 5 subtract x 2) the product of 10 and y 3) 20 decreased by a number t 4) 6 added to the product of 11 and m 5) the quotient of y and 9 6) 8 less than 7 times k 5 - x 10y 20 - t 11m + 6 y 9 7k - 8

5 A special word in each column refers not to the operation itself but the outcome of the operation.
_ + plus minus times divide add subtract multiply quotient increased by decreased by product sum diminished by …of... total difference twice ( 2) less more than added to less than subtracted from

6 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)

7 Match each phrase with its variable expression.
d 1) Twice the sum of x and 3 e 2) Two less than the product of 3 and x b 3) Three times the difference of x and 2 a 4) Twice a number x less 3 c 5) Two more than 3 times a number x

8 Define a variable to represent the unknown and
write the phrase as a variable expression. 1) 10 mph faster than the Honda Let x = the speed of the Honda x + 10 2) 7 inches shorter than Jill’s brother Let b = the height of Jill’s brother b - 7 3) 5 acres larger than twice the size of my lot Let k = the size of my lot 2k + 5 4) $7.50 times the number of people plus a $20 group registration Let y = the number of people $7.5y + $20
