Answer:
x = 15
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
3+6x + 5x+12 = 180
Combine like terms
11x+15 = 180
Subtract 15 from each side
11x+15-15 =180-15
11x = 165
Divide by 11
11x/11 =165/11
x =15
The number of permutations of 8 people taken 6 at a time is given by:
Step-by-step explanation:
-5(p + 3/5 ) = -4
-5p - 3/5 *5 = -4
-5p - 3 = - 4
-5p = -4 +3
-5p = -1
therefore p = 1/ 5
