Step-by-step explanation:
The number of people to paint the bridge is inversely proportional to the number of hours it takes.
(If there are more people, it will take less time etc.)
9 people can paint the bridge in 5 hours.
=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.

because i did a quiz with the same and i got it right
Hi, first thing to do is divide 2.5 by 4 which is 0.625and you can either multiply 0.625 by three or subtract it from 2.5. So the answer comes out to be 1.875. You’re welcome and have a nice day
Paralell has same slope
y=mx+b
m=slope
y=1/2x+b
find b
(x,y)
(4,0)
x=4
y=0
0=1/2(4)+b
0=2+b
minus 2 both sides
-2=b
the equaiton is
y=1/2x-2
or
x-2y=4
