Integers in real life are used to denote both positive and negative numbers. For example to represent profit, gain, increase, deposit, Income we use positive integers and to represent loss, expenditure, decrease, withdrawal we use negative integers.
Conclusion:

Answer:
2(W - 5) ≤ -29
Step-by-step explanation:
"Twice the difference of a number and 5 is at most -29" can be expressed symbolically as follows:
2(W - 5) ≤ -29
Further explanations:
"the difference of a number and 5" is W - 5, and thus "Twice the difference of a number and 5" is 2(W - 5).
"x ≤ -29" states "x is at most -29."
X=12 because 12 times 12 equals 144 or 12 to the power of two equals 144
