Answer:
Division.
Step-by-step explanation:
In order to get to 0.71938, you have to divide 719.38 by 1000.
719.38 / 1000 = 0.71938
-- Machine-X takes 3 minutes for 300 boxes . . . 3/300 = 1/100 minute per box.
-- Machine-Y takes 2 minutes for 300 boxes . . . 2/300 = 1/150 minute per box.
-- 3/150 = 2/100 . . . In 3/150 second, they can make 5 boxes by working together.
-- They need to make 5 boxes (300/5) = 60 times.
-- They'll need to work for 60 times (3/150) minutes.
60 (3/150) = 180/150 = 1.2 minutes = <u>1 minute and 12 seconds</u>.
20=x+10
x=10 would be your answer
Answer:
C, 7 1/2
Step-by-step explanation:
12 is 2/3 of 18, therefore 5 is 2/3 of something, so you divide 5 by 2/3 which is 15/2 which is 7 1/2
