Answer:

Subtraction Property of Equality

Step-by-step explanation:

Victor solved this inequality as shown:

Given: 6+3(x+5) = 36

Step 1: 6+3x+15 = 36

Step 2: 3x+21= 36

Step 3: 3x = 15

Step 4: 3x=15

What property justifies the work between step 3, I'm guessing its this question if not message me.

from step 2 to 3 we must use Subtraction Property of Equality since

3x+21 = 36 must subtract 21 both sides

then u get 3x=15

Answer: Just apply the formula

Step-by-step explanation:

The equation for volume of a cone is:

$V_{(cone)} =\frac{1}{3} \pi r^{2} h$

The radius is the line that creates a 90 degree angle with the height

The height goes from the base to the tip of the cone.

I recommend leaving Pi as it is and plugging the rest of the numbers first.

Then at the end multiply by 3.14 and round at the end.

This way, it is easier to avoid calculation errors.
