What is 5/8 + 3/4 divided by -2 /3 - 5/6​
pentagon [3]

\text{Hey there!}

\frac{5}{4}+\frac{3}{4}\div-\frac{2}{3}\ -\ \frac{5}{6}

\frac{5}{8} +\frac{3}{4}=\frac{11}{8}

\frac{-2}{3}-\frac{5}{6}=\frac{-3}{2}

\text{Problem becomes:}\frac{11}{8}\div\frac{-3}{2}

\frac{11}{8}\div\frac{-3}{2}=\frac{-11}{12}

\boxed{\boxed{\bf{Answer:\frac{-11}{12}}}}\checkmark

\text{Good luck on your assignment and enjoy your day!}

Hey! A step by step explanation on this would be great! Thanks!<br> (25 Points)
kicyunya [14]

Step-by-step explanation:

We find the stationary point of (20 + 2x)(1200 - 60x),

where x is the unit rate of increase/decrease.

d/dx [(20 + 2x)(1200 - 60x)]

= d/dx (-120x² + 1200x + 24000)

= -240x + 1200.

When d/dx [(20 + 2x)(1200 - 60x)] = 0,

We have -240x + 1200 = 0. => x = 5.

Price per shirt that maximise revenue

= $20 + $2x = $20 + $2(5) = $30.

Maximum revenue

= (20 + 2(5))(1200 - 60(5))

= $30 * 900 = $27,000.
