What does 1/9 + 1/3 equal

1/9 + 1/3= 4/9

they need to have the same denominator to add them so i made both denominators 9 as 9 is the lowest common multiplier . 1/9 stayed the same because its denominator was already 9 and 1/3 changed  to 3/9 beacuse to get from 3 to 9 i times by 3 so i did 1 (the numerator) times by 3 to get 3/9

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
