8.(5.2+3)=8.(15+3)=8.13=104 . = x division
hope that helped
hope that is right =D <span />
When you isolate the variable to one side of the equation, you have to use the given operation to simplify the number on the other side of the equal sign.
Ex: 4x + 8 = 40
This is a simple one-step equation, but to solve this, first, you need to subtract 8 from 40.
4x = 40
- 8
4x = 32
Then, you divide 4x by 32.
4x = 32
4x 4
x = 8
However, with multi-step equations you have to do these three important steps.
1.) Distribute - the number that's on the outside of the parentheses, gets multiplied to all the numbers except for the one on the right side of the equal sign
2.) Combine Like Terms - numbers with coefficients like 3x, 6y, or 7a, that have another one like it, you need to add them together and keep the variable.
3.) Simplify - it's almost like combining like terms, except if you have more than one number with coefficient, then again, add all the numbers with the same variable together.
And by the way, coefficient basically is a "fancy" way to say "number with a variable attached".

Answer:
hmmmm
Step-by-step explanation:
Cone
The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together. The answer will be written in units³.
Sphere
The volume of a sphere is ⁴/₃ × π × r³. To calculate the volume we multiply these values together. The answer will be written in units³.
Cylinder
The volume of a cylinder is π × r² × l (r is the radius of the circle and l is the length of the cylinder). To calculate the volume we multiply these values together. The answer will be written in units³. It is more accurate to use π = 3.142 or the π button on a calculator.
A cone is a 3D shape with 2 faces and one edge
A sphere is a 3D shape. It has one continuous face and no edges
A cylinder is a type of prism. It has 3 faces and 2 edges
