Answer:

-2(57+8) = 14 + 6x

step 1 -2 x 57 and -2 x 8   =

step 2 -114-16 = 14 + 6x

                +16    +16

step 3 -114 = 30 + 6x

           -30    -30

step 4 -144 = 6x

           -144/6  6/6

            x = -24

-2(5x + 8) = 14 + 6x

step 1 -2 x 5x and -2 x 8 =

          -10x - 16 = 14 + 6x

step 2 -6x                -6x

           -16x -16 = 14

step 3         +16   +16

            -16x = 30

step 4  -16/-16  30/-16

            x= -15/8

According to the table, Tasha initially had blank dollars before purchasing songs, and the cost of each song was blank dollars
melomori [17]

Total money before purchasing = $30

Cost of each song = $1.20

Solution:

According to the table,

No. of songs    Amount

        2                 27.60

        3                 26.40

        4                 25.20

Difference between amount she have after bought 3 songs to 2 songs:

27.60 – 26.40 = 1.20

Difference between amount she have after bought 4 songs to 3 songs:

26.40 – 25.20 = 1.20

So, the cost of each song = $1.20

Amount of money she had after purchasing one song = $27.60 + $1.20

                                                                                          = $28.80

Tasha initially had before purchasing songs = $28.80 + $1.20

                                                                         = $30

Hence Tasha initially had $30 before purchasing songs and the cost of each song was $1.20.

Find y<br> I will give brainlist
Arada [10]
Ok this one is easier than you might think. The line equals 180 degrees since it is a straight line, therefore you need to do 180-27 to get what y equals. Y=153

1. y = sin? (In x). Find dy
galina1969 [7]

Answer:

dy/dx=  cos(ln(x))/x

Step-by-step explanation:

y=sin(ln(x)) given

We have to use chain rule to differentiate!

Let u=ln(x) then du/dx=1/x

So we have

if y=sin(ln(x)) then y=sin(u) and dy/dx=dy/du * du/dx=cos(u) *1/x

where again u=ln(x) so

dy/dx=cos(ln(x)) *1/x

dy/dx=cos(ln(x))/x

I hope I have the right intepretation because I do see a ? in between sin and (ln(x)) .
