Answer:

Marvin shipped 12 candles in the box.

Hope this helps!

Step-by-step explanation:

The total weight of the candles is 9 lbs ( 12 ( total weight ) - 3 ( weight of box ) )

(3)/(4) x = 9 lbs ( you need to multiply both sides by 4/3 because that way you can cross-simplify 3/4 with 4/3 and simplify 9 with 4/3 )

Multiplying both sides by
(4)/(3) gives you (1)x =
$\frac{4}3}$ × 9 which equals ( (1)x =
(4)/(1) ×
); x = 12 ( simplify 3 and 9 )

The box holds 12 candles.

You can also check this answer by multiplying 12 by 3/4 (
×
(3)/(4) ) to get 9 (
×
(3)/(1) ), add the weight of the box (3), and you get 12.
