Factoring the second term shows you what the common denominator must be. Then multiply the first term by the appropriate version of 1 and add.
The ratio you are told means that for every 5 pink salons, you have 7 yellow swans. This means that if you have more, you have to multiply both values. For example, if you had 10 pink salons, then you would have 14 yellow swans because 5 × 2 = 10 so therefore 7 × 2 = 14. In this case, 390 ÷ 5 = 78, so you need to multiply 7 by 78, which gives you 546 yellow swans in total. I hope this helps!
Answer:
Step-by-step explanation:

complete question:
Solve the inequality that represents the story. Then interpret what the solution means in the story.
Lin buys a candle that is 9 inches tall and burns down x inches per minute. She wants to let the candle burn for 7 minutes until it is less than 6 inches tall.
9 - 7x < 6
Answer:
x > 3/7
x which is the inches per minute the candle will burn should be greater than 3/7 for the candle to be less than 6 inches tall.
Step-by-step explanation:
The candle is 9 inches and it burns down x inches per minute. Lin wants to let the candle burn for 7 minutes until it is less than 6 inches tall. The inequality can be solved below.
9 - 7x < 6
subtract 9 from both sides of the equation
9 - 9 - 7x < 6 - 9
- 7x < - 3
divide both sides by -7
- 7x / -7 < - 3/ - 7
dividing both sides with a negative values changes the inequality sign
x > 3/7
x which is the inches per minute the candle will burn should be greater than 3/7 for the candle to be less than 6 inches tall.
