The product of 9 and n is –27. What is the value of n?

-3

Step-by-step explanation:

9n =-27

Divide by 9 on both sides

n = -27/9

n = -3

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

560

hope this : )
