Karen wrote 2/3 of her essay in 1/6 of an hour. How long will it take her to write the full essay

3/12 of an hour or 15 minutes

Step-by-step explanation:

1/6 divided by 2 1/12 times 3 for 1/3 is 3/12

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
