Which statement best describes the solutions of this equation? 4/3x+1 = x/2x+10

Komok [63]

Answer:

x= 5

x= 8/3

Step-by-step explanation:

Step one

Given the expression

$\frac{4}{3x+1} =\frac{x}{2x+10}$

cross multiply we have

$4(2x+10)= x(3x+1)$

$8x+40=3x^2+x$

collect like terms

$3x^2+x-8x-40=0$

$3x^2-7x-40=0$

applying the quadratic equation

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-(-7)\pm\sqrt{(-7)^2-4*3(-40)}}{2*3}\\\\x=\frac{7\pm\sqrt{49+480}}{2*3}\\\\x=\frac{7\pm\sqrt{529}}{6}\\\\x=\frac{7\pm 23}{6}\\\\x=\frac{7\+23}{6}\\\\x=\frac{30}{6} \\\\x=5\\\\x=\frac{7-23}{6}\\\\x=\frac{-16}{6} \\\\x=\frac{8}{3}$

Solve for x.

Grace [21]

Answer:

C. x = -3

Step-by-step explanation:

-15x + 60 <= 105

-15x <= 45

-x <= 3

x >= -3

14x + 11 <= -31

14x <= -42

x <= -3

the only solution that is in both solution areas is x = -3.

for all other values of x we violate one of the 2 conditions.

Len tosses a coin three times. the coin shows heads every time. what are the chances the coin shows tails on the next toss?

Alik [6]

If she tosses the coin three times and will toss it again that will be four times. so her chances of showing tails is 1 out of 4 :)
