Homework Sec. 1.3 # 16, 29, 40, 48, 71

16. I like to get rid of the fractions by multiplying both sides by the LCD. Then I get all the variables on one side and all the #’s without variables on the other side and divide by the # is front of the variable. Don’t forget to check your answer. Did you use your calculator?

29. These are easy!

40. Your way does not have to look like my way, but we should have the same answer. Don’t forget to check!

48. I found the LCD to be 6, then multiplied both sides by the LCD to eliminate the fractions. Then I got all the variables on one side and all the #’s without variables on the other side and divided by the # in front of the vairable.

71. Let x = the # hrs. worked at 2 nd job. Total = Hourly ● Hours at + Hourly ● Hours at earnings wage 1 st job wage 2 nd job You must work 9 hours per week at the second job.
