n/2 + 3 = 21
The statement that represent that is one - half a number is 267.
x/2 + 5
1/2x=-5
So you know this is the equation you are suppose to be using. If the equation gives you the diameter of the cylinder then divide that number in half and plug the number you got into the equation. This is because the radius is half of the diameter. Otherwise, the only way to find the volume is if you have the area of the base. Then multiply that area by the height.
If half of the number is 20, then the number must be 2 * 20 = 40. Therefore three quarters of the number would be 3 * (40/4) = 30.

x/2 + 5
Not exactly sure what you mean about "aluminum's half life equation." Exponential decay, from where we get the half-life equation from, has nothing to do with mass, atomic number, etc... and therefore has nothing to do with any particular isotope.
No.
1/2x=-5
(1/2)x+(1/6)y
If half of the number is 20, then the number must be 2 * 20 = 40. Therefore three quarters of the number would be 3 * (40/4) = 30.
one and a half

Expressed as an equation, this would be equal to 0.5x or 1/2x.
x+5 divided by 2 =6
Example: Three more than half of a number is 15. >Take the number (24) and divide it in half (or by 2). 24 / 2 = 12 >Take the 12 and add 3 12 + 3 = 15
