Addition or multiplication
add 2 or times 2
The answer is 96 min, here is why:
x / 240 + x / 160 = 1
<span>2x + 3x = 480 </span>
<span>5x = 480 </span>
<span>x = 96 min
(</span><span>Drainage rate of first pipe = 480000/240 = 2000 l/min </span>
<span>Drainage rate of second tube = 480000/160 = 3000 l/min </span>
<span>Combined drainage rate = 5000 l/min </span>
<span>Time to drain = 480000/5000 = 96 min. )</span>
a) Unit rate = 24 oz / 10lb = 2.4 oz / lb
This means that we need 2.4 oz of seasoning for every pound of crawfish
b) For 30 lbs....we need 30 * 2.4 = 72 oz of seasoning
c) With 36 oz of seasoning...we can cook 36 / 2.4 = 15 lbs of crawfish
For the third one, on the left side do 3-51.29 and keep doing it like that and you should get all the answers you need :)
1 gram = 1000 milligrams
a) You can pick any 3 <u>gram</u> numbers that add to 15.4 grams
For example, 5 , 3, 7.4 = 15.4 grams
a) You pick any 3 <u>milligram</u> numbers that add to 15.4 grams (or 154,000 milligrams)
For example, 50,000, 70,000, 34,000 = 154,000 milligrams
