Corinna has $80. She wants to buy a $245 plane ticket. She will save up her earnings from working at the museum where she earns $15 per hour. Which inequality shows the number of hours, n, Corinna must work so that she has a total of at least $245

245<=80+15n

245 is less than or equal to 80 (original savings) + 15n (pay*number of hours)

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
