Answer:
14cm
Step-by-step explanation:
Martelene bought a small aquarium to celebrate her birthday.
The aquarium has a length of 18.5cm, width of 15cm and a volume of 3885 cubic centimeters.
From the question above we are required to calculate the depth of the water in the aquarium
Let A represent the depth of the water in the aquarium
Volume= length×width×height
3885= 18.5 × 15 × A
3885= 277.5A
Divide both sides by the coefficient of A which is 277.5
3885/277.5= 277.5A/277.5
A = 3885/277.5
A= 14cm
Hence the water is 14cm deep into the aquarium.

<span>(-14 + 3/2b) - (1 + 8/2b)
= -14 - 1 + 3/2b - 8/2b
= -15 - 5/2b
In short, Your Answer would be Option C

Answer:
Negative 4 n + 8 + 9 n minus 2 and 5 n + 6
Step-by-step explanation:
3v + 5 - (9v + 2)
3v + 5 - 9v -2 = -6v + 3
-6v + 6
(NO)
-6n + 3 - (2n + 2)
-6n + 3 - 2n - 4 = -8n - 1
-8n + 6
(NO)
-4n + 8 + 9n - 2 = 5n + 6
5n + 6
(YES)
When you divide a number by two, you find the number that if you add it to itself, become the original number.
When you square root a number, you find the smaller number that becomes the bigger number if you multiply it by itself.
For sixteen, if you divide it by two, you get 8, while if you square root it, it becomes 4.
