A because just multiply 1/4 by 16 and u get 4
-2a
Step-by-step explanation:
steps:1. first write the question again : 8ab/-4b
2.first 8 divide by -4=-2
3.write ' a' with -2because u don't have another 'a' down belowso that u can pair it up and cancel
so: -2a.
4. cancel 'b' on top and 'b' at the bottom.
3 gallons of acid = 100% concentration acid
? (water+acid) gallons = 15 concentration acid
Note: Every gallon of water added reduces the percentage concentration of acid. Therefore, the relationship is inverse proportionality.
Solution:
Total number of gallons (water+acid) = (3*100)/15 = 20 gallons
Therefore, gallons of water = 20-3 = 17 gallons
Answer:
44/3 or 14 and 2/3
Step-by-step explanation:
First convert 2 and 3/4 in a improper fraction which gives you 11/4.
Next, you divide 11/4 and 3/16.
It will give you 44/3 which can be 14 and 2/3.
