Susan took 2 hours to write 30 party invitations write an equation to represent the number of minutes m susan spend writing x invitations

In order to solve for the variable m, first, you have to convert 2 hours to 120 minutes then you have to have the rate of invitations per minute (x/m). Once you have the rate (0.25) you get this formula m=x/0.25. which if you plug the x variables into you will find is correct.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

J= r + 9 because since jessica rode 9 more miles than roger, you add 9 miles to rogers mileage.
