Answer:
Depth of Martens aquarium water = 14 cm.
Step-by-step explanation:
Given:
An aquarium,which is a right rectangular prism.
Length of the aquarium,
= 18.5 cm
Width of the aquarium,
= 15 cm
Volume of the aquarium,
= 3885 cm cubes
We have to find the depth of the aquarium.
Let the depth be
cm.
Note:
Volume of the rectangular prism,V=lbh.
⇒
= 
⇒ 
⇒ Plugging the values.
⇒
⇒
cm
So,
The depth of the aquarium water is 14 cm.

Answer:
x = 2
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
-3(x - 1) = x - 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -3: -3x + 3 = x - 5
- Add 3x to both sides: 3 = 4x - 5
- Add 5 to both sides: 8 = 4x
- Divide 4 on both sides: 2 = x
- Rewrite: x = 2
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -3(2 - 1) = 2 - 5
- Subtract: -3(1) = -3
- Multiply: -3 = -3
Here we see that -3 does indeed equal -3.
∴ x = 2 is a solution of the equation.
