Kelly has 4 times as many songs on her music player as lou tiffany has 6 times as many songs on her music player as lou altogeth

Mice21 [21]

Let K be the number of songs on Kelly's music player,
L be the number of songs on Lou's music player and T be the number of songs on Tiffany's music player.

We know that,
K = 4*L
and
T = 6*L
and also
K + T + L = 682

Then,
4*L + 6*L + L = 682

11L = 682

L = 62

From here we know that

T = 6*62 = 372
K = 4*62 = 248

So Kelly has 248 songs on her music player

Find the value of x to the nearest tenth

o-na [289]

That is
2(3x-8) =20
Divide both sides by 2
3x-8 = 10
Add 8 to both sides
3x =18
Divide both sides by 3
x=6

So answer is 6.0

The first term of an arithmetic sequence is 5, and the tenth term is 13. Find the common difference

RideAnS [48]

Common difference d when The first term of an arithmetic sequence is 5, and the tenth term is 13 is $d=\frac{8}{9}$

Step-by-step explanation:

The first term a₁ = 5

The tenth term a₁₀ = 13

Find Common difference d=?

The formula used for arithmetic sequence is:

$a_{n}=a_{1}+(n-1)d$

where aₙ = nth term

a₁= 1st term

d= common difference

Finding d:

$a_{10}=a_{1}+(n-1)d\\Putting\,\,values\,\,a_{10}=13, a_{1}=5 and n=10\\13=5+(10-1)d\\13-5=9d\\8=9d\\d=\frac{8}{9}$

So, Common difference d when The first term of an arithmetic sequence is 5, and the tenth term is 13 is $d=\frac{8}{9}$
