To get x to be by itself you would have to mutiply both sides by two so then it would look like this x=34. So the answer to your question is x=34
it is the same denominator therefore only the numerators are added and the sign is maintained. The answer is -12/9 but it can be reduced to -4/3.
If she gains a card that would be a positive 1, if she sells one that would be negative 1, and if she keeps one than that would be 0.
4% is the same as .04 and 4/100. 4/100 can be simplified to 1/25 by dividing both sides of the fraction by 4
The circumcenter is where the perpendicular bisectors meet.
if you sketch the triangle, you will see that it is a right triangle, with the right angle vertex at (2,1)
one perpendicular bisector is x=1, another perpendicular bisector is y=3
they meet at (1,3)
so (1,3) is the answer.
