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
Answer:
-3
Step-by-step explanation:
Point A is half way between -17 and 5. This is span has a total distance of 17 + 5 = 22. Half way is 11 units from -17 or 5. So -17 + 11 = -6.
Point B is halfway between A at -6 and 0. This is a distance of 6. So halfway is 3 units away at -3.

subtract pw from both sides:

divide p on both sides:

Answer:
7/4 inches
Step-by-step explanation:
Longest bean sprout = 8/8 + 8/8
Longest bean sprout = 1 + 1
Longest bean sprout = 2
Shortest bean sprout = 2/8
Difference = 2 - 2/8
Difference = (16-2)/8
Difference = 14/8
Difference = 7/4
Hence the distance is 7/4 inches
'Commutative' means you can work it in the other direction without changing it.
But 1/2 is not the same number as 2/1 . So I guess division is NOT commutative.
