Nata [24]
How much part can sally paint in an hour ?
a ÷ 7 = a/7

And what about Steve ?
a ÷ 9 = a/9

Where, a is the total area of the room.

So, let the time taken by both of them to paint the room together be 't'

So,
t(a/7 + a/9) = a
t(9a/63 + 7a/63) = a
t(16a/63) = a
t = 63/16 ≈ 4 hr

Answer:

josh vendió 17 libros recaudando 306 dolares .

jessica vendió  255 libros recaudando 4590 dolares.

Step-by-step explanation:

Sustituimos por variables :

libros que vendió Jessica = x

libros que vendió Josh = y

entonces:

x + y = 272

Jessica vendió 15 veces mas libros que josh:

x = 15y

Reemplazamos en la anteriior ecuacion:

15y +y = 272

16y = 272

y = 17

Reemplazamos en la primela ecuacion :

x + 17 = 272

x = 255
