11/6=n+7/9 what does n equal

Answers

Answer:

n = 19/18

Step-by-step explanation:

11/6 = n + 7/9

-n + 11/6 = 7/9

-n = 7/9 - 11/6

-n = -19/18

n = 19/18

Answer:

n = 19/18

Step-by-step explanation:

The equation 11/6=n+7/9 has fractions with two different denominators (6 and 9).  The LCD is 18, which is the smallest number evenly divisible by 6 and 9.  Thus, we can rewrite 11/6=n+7/9 as:

33/18 = (18/18)n + 14/18 (Now all three denominators are the same:  18)

Then 33 = 18n + 14, or

         19 = 18n

Dividing both sides by 18, we get n = 19/18

Check:  Is 11/6 = 19/18 + 7/9 true?  YES

Quirky gives inventors a design team that helps them bring their thoughts to life. The staff of Quirky (75 people and growing) listens to proposals for new projects and votes on which products the company will make. One famous example of a Quirky product was invented by a salesman who lived in Baltimore. He noticed that people who lived in apartment buildings kept large air conditioners hanging out of their windows. Those air conditioners would run all day. He invented a slim air conditioner that can be turned on and off using a phone app. His air conditioners use less energy than old-fashioned air conditioners. Without the team at Quirky, he never would have been able to make his idea a reality. What can we infer about the salesman from Baltimore? He used to work as an air conditioning repairman. He was nervous to present his product at Quirky. He doesn't like seeing air conditioners in windows. He believes that working with others is a smart business move.
