As per the problem
The chemicals in my swimming pool use a ratio of 5 tablets of chlorine for every 14 days.
we have been asked to find
Which ratio shows the number of chlorine tablets needed for 42 days?
Since for each 14 days the number of tablets required is 5
So if you multiply the number of days by some number then, we will have to multiply the number of tablets required by the same number.
So When number of days
Then the number of tablets required for 42 days is 
5÷3=length
5 is the length of the banner and you need to know the length. You already know that the length is 1/3 of the width (5).
1.7 feet
Since 3 out of 5 doctors (60%) use brand X, solve for 60% of 2,000, which is 1,200 doctors.
Let us suppose it will take t hours for the temperature to drop at least 36°F.
We have been given that temperature in Antarctica will decrease 8°F each hour for the next 6 hours.
And we have to find the time to drop the temperature to at least 36°F. At least means greater than equal to.
Therefore, we have the below inequality
Now, we solve the inequality.
Divide both sides by 8, we get
Hence, it will take atleast 4.5 hours to drop the temperature to 36°F.
Answer:
The easiest way would be to try to solve for x
