That would be the inverse property of addition. When you add the opposite of a number to that number, your sum will be zero. -a is the opposite of a and -bi is the opposite of bi. When you add x + y (aka the opposites) your total is absolutely nothing!

Joy Wigens, who works at Putnam Investments, received a check for $2,670. She deposited 1/3 of the check in her Citibank account
spin [16.1K]

Answer: $1,780

Step-by-step explanation:

Joy Wigens deposited 1/3 of the check of $2,670 that she received in her Citibank account.

The amount she deposited in her Citibank account was:

= 1/3 * 2,670

= $890

The amount she is left with after this deposit will therefore be:

= Check amount - deposit at Citibank

= 2,670 - 890

= $1,780
