All you have to do is multiply a number by the numerator and denominator
Answer:
- Tadeo: 12 hours
- Dylan: 2 hours
Step-by-step explanation:
We can let d represent the number of hours that Dylan volunteered. Then Tadeo volunteered for 6d hours, and their total hours were ...
d +6d = 14
7d = 14 . . . . . . collect terms
d = 2 . . . . . . . divide by the coefficient of d
6d = 6(2) = 12
Tadeo volunteered 12 hours; Dylan volunteered 2 hours.
Let the number of songs owned by Lou be = x.
Kelly has 4 times as many songs as Lou = 4x
Tiffany has 6 times as many songs as Lou = 6x
They all have total of 682 songs
= x + 4x + 6x = 682
11x = 682
x = 682 / 11 . Use your calculator.
x =62.
How many songs Kelly has = 4x = 4*62 = 248 songs.
Kelly = 248 songs.

The expression for the number of sixth graders in terms of x is 
<h3><u>Solution:</u></h3>
Given that , 
of the students in school are in sixth grade
To find: Expression for number of sixth graders
Let the total number of students in school be "x"
From given statement,
of the students in school are in sixth grade
Which means, of total number of students are in sixth grade
Let "n" be the number of students in sixth grade
Then by given statement,
n = of total number of students
Thus the expression in terms of x is found
