1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 2 ft * 2 ft=12 ft³
Therefore:
A machine can fill 12 ft³ in 3 seconds.
2) we calculate the volume of the second carton.
volume=length x width x heigth
volume=4 ft * 5 ft * 6 ft=120 ft³
3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.
12 ft³---------------------3 seconds
120 ft³-------------------- x
x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.
answer: 30 seconds.
13x = 39 can replace 3x + 5y = 59 in the original system and still produce the same solution.

Step-by-step explanation:
Answer:
61-27=34
Step-by-step explanation:
start with the ones place:
1-?=4
since 1 minus anything will never give a 4 add 10
11-?=4
11-4=?=7
then start with the tens place:
?1-27=34
?1=34+27
?1=61
