Explanation:
For every problem, plug in the number where the variable is.
For example:
Evaluate the following expression by substituting 8 for x.
x + 9
You would take the x and turn it into 8, then you would do 8 + 9.
I guess any ten pounds can be the same weight as light stuffs combined together such as multiple breaks, a school bag, etc.
The answer is: 141,300 units .

(1/2) π r² h = (1/2) * (3.14) * (30)² * 100 = ?
(30)² * 100 = 30 * 30 * 100 = 90,000.
So, we have: (1/2) * (3.14) * (90,000) ;
→ (1/2) * (90,000) = 45,000 ;
So, we have: (3.14) * (45,000) = 141,300 units.

4n = 3m - 1
4n = 3m - 1
Subtract 3m from both sides.
-3m + 4n = -1
Subtract 4n from both sides.
-3m = -4n - 1
Divide both sides by -3.
m = 4/3n + 1/3
m = 4/3n + 1/3
