First, let x be the number of hours it will take for Hector to finish the same job alone. This means that every hour, Hector can do 1/x of the job. The amount of work done by Shawn and Hector in 6 hours should be equal to 1 complete work. This can be expressed as,
(1/9 + 1/x)(6) = 1
The value of x is 18. Thus, Hector can to 1/18 of the job in one hour.
The mean is 14
add all the numbers up and divide the sum by 6 because that’s how many numbers you’re adding together.
12+10+14+18+14+16
= 84
84/6 = 14
X is 3 so 7(3+4)=49 hope that help
$10.50
Explanation:
Let x be the cost of the individual books. Then 24.81=3x−6.69
3x= 24.81+ 6.69 =31.50
x=31.50/3=10.50
