Answer:

5 hours

Step-by-step explanation:

Make a proportion

She served 48 people in 3 hours, and served 80 people in x hours

48/3=80/x

Cross multiply

48*x=80*3

48x=240

Divide both sides by 48 to isolate x

x=5

So, it will take 5 hours to serve 80 people

6n + 9 = -3 - 21 - 6

denis23 [38]

$6n+9=-3-21-6$
subtract the numbers: $-3-21-6=-30$
$6n+9=-30$
subtract 9 from both sides
$6n+9-9=-30-9$
simplify
$6n=-39$
divide both sides by 6
$\frac{6n}{6}= \frac{-39}{6}$
$n= \frac{-13}{6}$
decimal $n=-6.5$
Hope this helps :)
