Please solve this proportion with steps (I'm stuck) (9x+6)/18= (20x+4)/3x

guapka [62]

$\frac{9x+6}{18}=\frac{20x+4}{3x}$

Cross multiply. Distribute...
$3x(9x+6)=18(20x+4)\\27x^2+18x=360x+72\\27x^2-342x-72=0\\3x^2-38x-8=0$

OH GOD IT'S A QUADRATIC
(our equation is in ax² + bx + c = 0 form. a=3. b= -38. c= -8.
plug these values into the quadratic formula and simplify.)
$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{-(-38)\pm\sqrt{(-38)^2-4(3)(-8)}}{2(3)}=\frac{38\pm\sqrt{1444+96}}6\\\\\sqrt{1444+96}=\sqrt{1540}=\sqrt{4\times345}=2\sqrt{345}\\\\\frac{38\pm2\sqrt{345}}6=\boxed{x=\frac{19\pm\sqrt{345}}3}$

Approximate values for x: -0.20714 or 12.874

A phone company offers two monthly plans. Plan A costs $14 plus an additional S0.15 for each minute of calls. Plan B costs $22 p

Sergio039 [100]

Answer:

200 minutes, cost $44.00

Step-by-step explanation:

x = minutes

14 + .15x = 22 + .11x

.04x = 8

x = 200 minutes

14 + (.15*200)

14 + 30 = 44

22 + (.11*200)

22 + 22 = 44

Suppose that legalizing the use of marijuana would decrease its price by 81 percent. If the price elasticity of demand for marij

Vinvika [58]

Answer:

222.75%

Step-by-step explanation:

Elasticity of demand for marijuana

(dQ/Q)/(dP/P) = -2.75

If the price drops 81%, that is dP/P=-0.81

If we re-arrange the equation

dQ/Q= -2.75 * dP/P = -2.75*(-0.81) = 2.2275

The demand will be 222.75% higher if the prices drop by 81%
