Howard bought 3/5 pounds of granola. He divided the granola evenly among 4 friends. How much granola did each friend get?

Answer:

(0.75) is the amount that each freind has.

Step-by-step explanation:

We see that Howard did NOT purchase not one pound of granola. Its only 60% of a pound. Therefore we'd do 60% divided by 4 and therefore get .75%. Each freind ate .75% of that granola.

Answer:

$\bold{x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\quad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7}$

Step-by-step explanation:

$-2x^2-3x+4=0\\\\a=-2\,,\ b=-3\,,\ c=4\\\\\\x=\dfrac{-b-\sqrt{b^2\pm4ac}}{2a}=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(-2)(4)}}{2(-1)}=\dfrac{3\pm\sqrt{9+32}}{-2}\\\\\\x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\qquad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7$
