Answer: The number is: "2" .
_______________________________________________________
The expression is: 2 − (½)x = (½)<span>x ;
</span>→<span> in which "x" is the "unknown number".
</span>_______________________________________________________
Explanation:
______________________________________________________
Given:
_________________________________________________________
"Two decreased by a half of a number is one-half<span> of the number" ;
Let "x" represent the "unknown number" for which we wish to solve;
Write the expression as:
_________________________________________________
" </span>2 − (½)x = (½)x " .
_________________________________________________
Note: Add "(½)x" to EACH SIDE of the equation:
_________________________________________________
2 − (½)x + (½)x = (½)x + (<span>½)</span>x ;
to get:
_________________________________________________
→ 2 = 1x ;
↔ 1x = 2 ;
↔ x = 2 .

Answer:
15
Step-by-step explanation: you basically write it down in numerical order or 1 2 3 4 5 6 7 8 9 10 etc. then if it is an odd number then you choose the one that has an equal amount on each side left and right. if it is even then you need to do the same thing but find two numbers that are side by side and have an equal amount on both sides.
V = lwh/3
= 5x3x1/3
= 15/3
= 5
Therefore the volume is 5 meter cubed.
