Answer:
Step-by-step explanation:
10- -2 which gives you 12 cause the negatives make a positive.
-9 -0= -9
12 over -9 which simplifies to 4 over -3

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:
4
Step-by-step explanation:
Perimeter equation: Length + Width * 2
so divide 2 by 16
which gives you 8 and minus that by its half so you get 4
