Step-by-step explanation:
Definition of additive inverse.- If two numbers are added together and the sum is zero, they are the additive inverse of each other.
<span>......................................... IF A + B = 0 , they are the additive inverse of each other.
</span>
<span>Multiplicative Inverse.- If two numbers are multiplied together and the product is one. They are the multiplicative inverse of each other, also called reciprocal. </span>
<span>......................................... A.B = 1 , they are the multiplicative inverse of each other.
</span>
<span>Example of: </span>
<span>Additive inverses :................ 5 + ( - 5 ) = 0 </span>
<span>Multiplicative inverses...........5 x 1/5 = 1 </span>
An equation that represents this is
(5-20-18)+25
The steps to solve it are as follows
(-15-18)+25
-33+25= (-8)
she is still 8 dollars in debt
Ava's sister paid a 4.5% annual interest rate
Her sister paid $54 more than she borrowed, divide that by 3 (years till she paid)
54/3 = 18
That's $18 for every year she'd had the $400 loan out, divide it by 4 to get the percentage
18/4 = 4.5/100 = 4.5%
