<h3>Answer:</h3>

x =  -  \frac{25}{2}

Alternative forms:

x =  - 12 \frac{1}{2}, \: or \: x =  - 12.5

<h3>Step-by-step explanation:</h3>

4(2x - 10) = 12x + 10 \\ first \: you \: need \: to \: distribute \\  \\ 8x - 40 = 12x + 10 \\ subtract \: 12x \: from \: both \: sides \\  \\  - 4x - 40 = 10 \\ add \: 40 \: from \: both \: sides \\  \\  - 4x = 50 \\ divide \: both \: sides \: by \:  - 4 \\  \\ x =  -  \frac{25}{2}

What is the approximate value of k?
lesya692 [45]

Hello from MrBillDoesMath!

Answer:

5.06

Discussion:

Angle J = 180 - (120 + 40) = 180 - 160 = 20 degrees,

From the law of sines

sin(120)/k = sin(20)/2  =>

sin(120) =  k *  (  sin(20)/2) )                (multiply both sides by "k")

k = sin(120)/  (   sin(20)/2)                    (divide both sides by sin(20)/2)

k =  (0.866) /  ( 0.171) =  5.06


Regards,  

MrB

 P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
