Nine more than half the number n is no more than -8. Write an inequality and find n.

Judith drove h hours at a rate of 55 mi/h. She did not reach her goal of driving 385 miles for the day. How long did she drive? (I can solve if I have the inequality but I can't figure out what that is.)

do we find single atoms of H, O, N or C alone, in nature? why or why not.

Melissa has a collection of dimes and nickels with a total face value of less than one dollar. Let x be the number of dimes and y be the number of nickels. How many of each type of coin does she have?

Thank you!

17000 x 0.08 x 2 = 2720 add the amount borrowed and amount of interest. 17000 + 2720 = $19,720
