If his age is a
400 reduced by 3 times my age is 163 means
400-3a=163
minus 300 from both sides
-3a=-237
divide both sides by -3
a=79

his age was 79 at the time of the quote

Let the man's age be x.
400 - 3x = 163
First, simplify both sides of the equation.
400 + -3x = 163
-3x + 400 = 163
Npw, subtract 400 from both sides.
-3x + 400 - 400 = 163 - 400
-3x = -237
Finally, divide both sides by -3.
-3x / -3 = -237 / -3
x = 79
The man's age is 79 years old.

Identify two methods a person can use to pay their bills online. Explain the advantages and disadvantages of both methods.
jek_recluse [69]
1) You can pay your bills online using your debit, credit card, or an electronic check. Advantage: you pay when you want and when you are sure you have money in the bank. Disadvantage: you have to remember to pay the bills by the due date.

2) You can set up automatic withdrawal from your bank account to pay your bills. Advantage: once you set it up, you do not have to remember to pay the monthly bills. Disadvantage: if you do not check your checking account balance to be sure there is enough money to cover the bills, your account may go negative.

Hope this helps! :)
