Explanation:
Add 2x to both sides
-3x=6
Divide both sides by-3
x=-2
_____
First you want to separate the variable terms and constant terms. Here, that is done by adding the opposite of -2x to both sides.
Then you want to divide by the coefficient of x, so you have the variable by itself. Since the coefficient after the first step is -3, you divide both sides by -3.
Solve for t by simplifying both sides of the equation, then isolating the variable.
t = -0.12
Answer:
356.05 cm³
Step-by-step explanation:
We are looking for the volume. The formula is density = mass / volume.
If we plug in our numbers, our formula would be 2.76 = 982.7 / V.
Multiply both sides by V and your formula would be (V) 2.76 = 982.7.
Divide both sides by 2.76 and you would get V = 356.05.

The formula of volume of sphere
![= \frac{4}{3} \pi {r}^{3}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20%7Br%7D%5E%7B3%7D%20)
The volume of the sphere
![= \frac{4}{3} \times 3.14 \times {(14 \div 2)}^{3}](https://tex.z-dn.net/?f=%20%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%20%5Ctimes%203.14%20%5Ctimes%20%20%7B%2814%20%5Cdiv%202%29%7D%5E%7B3%7D%20)
![= \frac{4}{3} \times 3.14 \times {7}^{3}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%20%5Ctimes%203.14%20%5Ctimes%20%20%7B7%7D%5E%7B3%7D%20)
