Jim started out with 3,067.48 in his checking and ended with 1,845.24 after paying for airplane tickets. To figure out how much money he spent on the tickets, you will need to first subtract the ending amount of 1,845.24 from 3,067.48 and then divide the sum to get the amount spent on each ticket.
3,067.48 - 1,845.24 = 1,222.24 1,222.24\2= 611.12
In the end Jim spent 1,222.24 in total on tickets. He spent around 611.12 on each ticket.
They are both right becuase if you just take away 1 from 20 and 10 you get 2 and 1. For the 4:2 one take away 1 and mutiply by 2 equalling 4:2 but they are still the same thing.
A triangle has 180o and an isosceles triangle has two angles that are the same. As 70 is less than half, we have a couple of possible solutions to this. So one possible solution is 70-55-55. So the other possible solution is 70-70-40.
