Brian has a piece of yarn that is 48 inches long. how many feet long is his piece of
yarn?

4 feet

Step-by-step explanation:

there are 12 inches in a foot, therefore, if you divide 12 by 48, you get 4.

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
