-7x + 12 is not an equiv. expression because one of the - signs in the original expression has been changed to +.
Answer:
x is 30/7
Step-by-step explanation:
You want to isolate x.
First, solve 5 * 6/7. The answer is 30/7.
Next, divide both sides by 6/7. This will cancel out the 6/7 on the left . For the right, when dividing fractions, you must take the reciprocal of the second fraction and multiply by it. So instead of having 30/7 divided by 6/7, you will have 30/7 * 7/6. The answer is 210/45 which simplifies to 5.
Third, you want to divide both sides by 7/6. Again the 7/6 on the left will be cancelled out. And you must do 5 * 6/7. In order to make the 5 look like a fraction to reduce confusion, you can set it over 1 (thus, you would do 5/1 * 6/7). The answer is 30/7.
You can plug it back into the equation to check.

Answer:
718.38 units
Step-by-step explanation:
Formula for volume of the cone is V = πr²
The radius is 7 cm, the height is 14 cm.
Let's plug these values in.
V = π · 7² · 
V = π · 49 ·
V = 718. 37752
Rounded to the nearest hundreth is : 718.38
