Probability red+green
first pick(red) : 7/10
2nd pick( green) : 1/10
the answer maybe like this
prob : 7/10+1/10 = 8/10 =4/5
In a circle, the degree measure of an arc is the same as the measure of the central angle that intercepts it.
A full circle is 360 degrees.
Add all the measures and set equal to 360 degrees.
One angle measure is not given, but that angle has a mark and another angle has the same mark, so the angle whose measure is not give also measures -9x - 3.
-9x - 3 + x + 107 + (-6x + 8) + (-9x - 3) + (-13x - 1) = 360
-9x - 3 + x + 107 - 6x + 8 - 9x - 3 - 13x - 1 = 360
-36x + 108 = 360
-36x = 252
x = 252/(-36)
x = -7
The value of x is 8.
6x-2=46
+2 +2
6x=48
6/6 48/6
x=8
1) Identify the statement you want to prove is true
2) Assume temporarily that the statement is false; assume the opposite is true
3) Obtain statements that logically follow from your assumption.
4) Reason logically until you reach a contradiction of a known fact.
5) Point out that your assumption must be false, and the statement must then be true.
