1/5(2x - 10) + 4x = -3(1/5x + 4)
0.4x - 2 + 4x = -0.6x - 12
4.4x - 2 = -0.6x - 12
5x - 2 = -12
5x = -10
x = -2

\dfrac{1}{5} (2x - 10) + 4x = -3 ( \dfrac{1}{5}x + 4)

Apply distributive property to distribute 1/3 and -3:

\dfrac{2}{5} x -  2 + 4x = - \dfrac{3}{5}x - 12

Sort all the x to the left and the constants to the right:

\dfrac{2}{5} x + \dfrac{3}{5}x  + 4x = - 12 + 2

Simplify:

5x =  -10

Divide by 5:

x = -2


\boxed { \boxed {\text {Answer: x = -2}}}

Use the Binomial Theorem to expand each binomial (5x-4y)^3
jek_recluse [69]
You should know that:

(a+b)(a+b)(a+b)

=a(a+b)(a+b)+b(a+b)(a+b)

=a(a²+2ab+b²)+b(a²+2ab+b²)

=a³+2a²b+ab²+a²b+2ab²+b³

=a³+3a²b+3ab²+b³

-----------------

If a=5x and b=-4y

(5x+(-4y))³

=(5x-4y)³

=(5x)³+3(5x)²(-4y)+3(5x)(-4y)²+(-4y)³

=125x³+3(25x²)(-4y)+15x(16y²)-64y³

=125x³+75x²(-4y)+240xy²-64y³

=125x³-300x²y+240xy²-64y³

A music store sold 10 to the third CDs and ten to the second CDs players if each CD costs $12 and each CD player costs $35, what
enot [183]
10^3 CDs with CD = $12 then total CDs earnings is (10^3)(12) = $12,000
10^2 CD players with CD plater = $35 then total CD player earnings is (10^2)(12) = $1,200
Total store earnings = ($12,000 + $1,200) = $13,200

3x-4=13 solve inequality plz show work !
dimulka [17.4K]
3x-4=13
First you want all your x's on one side, and all your ordinary numbers on the other.
Add four to both sides to get rid of the "-4" part on the left.
Your new equation is 3x = 17
Divide each side by 3 to find X.
x= 17/3 or 5 2/3
