Answer:
x > 7
Step-by-step explanation:
you move over the 10 to the left and it becomes negative.
x > 17 - 10
so then you subtract the 17 - 10 and you would get 7.
x > 7

Answer:
Step-by-step explanation:
this one is tricky so b/c the lines are at 90 degees we know that the arcs are similar so set up the parts of the arcs equal to 360 degrees
360 = 130 + 130 + x + x
see each part of the circle ?
then use your mad algebra skilz
100 = 2x
50 = x
:) nice.. when I do the math , it seems easy , huh :DDD
