Answer:
B.
Step-by-step explanation:
So there are 16 grams initally. Then, the amount of water decreases by 3.5%.
So first we must find 3.5% of 16. 3.5% in decimal form is 0.035, since you divide 3.5 by 100. Then, when you multiply 0.035 by 16, you get 0.56. Since the solution decreased by that percentage, you must subtract 0.56 from 16, which is 15.44.
Then the amount of water decreases by 4.25%. That in decimal form is 0.0425. You multiply it by 15.44, and it comes out to 0.6562. You subtract that from 15.44, not 16, since some of the water has evaporated. So you get 14.7838.
Answer:
The answer is 12
Step-by-step explanation:
12 + b is lees than or equal to 25
So 12 + 12 = 24
which is less than 25.
(The real answer is 13 but that is not the question lol)
So 12 makes the inequality true
If that makes sense
1/4 , 1/2 , 2/3 , 5/6
