Brrunno [24]

Answer:

The value of x is -10.

Step-by-step explanation:

Given : Expression $3x-8=\frac{8x+4}{2}$

To find : What is the value of x?

Solution :

Step 1 - Write the expression,

$3x-8=\frac{8x+4}{2}$

Step 2 - Cross multiply,

$6x-16=8x+4$

Step 3 - Take like terms together,

$6x-8x=4+16$

Step 4 - Solve,

$-2x=20$

$x=-\frac{20}{2}$

$x=-10$

Therefore, The value of x is -10.

a water balloon is tossed into the air with an upward velocity of 25 ft/s its height h(t) in ft after t seconds is given by the

Montano1993 [528]

When the height is 0 that is when it hits the ground
solve
0=-16t²+25x+3
cant factor so use quadratic formula

for
0=ax²+bx+c
$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$

so for
0=-16t²+25t+3
a=-16
b=25
c=3
so

$x=\frac{-25+/-\sqrt{25^2-4(-16)(3)}}{2(-16)}$
$x=\frac{-25+/-\frac{625+192}}{-32}$
$x=\frac{-25+/-\frac{817}}{-32}$
it has to be a positive time

so it will hit the ground after $\frac{25+\sqrt{817}}{32}$ seconds
