What you're seeing here is 12 being multiplied by its reciprocal. 12 * 1/12 = 1. This is an example of a multiplicative inverse; a multiplicative inverse is when you multiply a number by its reciprocal (1 over the number).
Answer:
B im pretty sure
Step-by-step explanation:
Alexandra's gross annual salary is $38,556. The maximum amount of rent she can afford to pay can be determined by first solving for her monthly gross salary.
Monthly Salary = ($38,556/ 12 months) = $3,213
Assuming that the amount allocated for her rent is 30% of her monthly salary, the maximum amount of rent that she can afford to pay is:
Max allowable rent = $3,213 * 0.30 = $963.90<span />
-3x -3y = -12
3x + 6y = -6
3y = -18
y = -6
x - 6 = 4
x= 10
D is your correct answer!
