You can notice the sequence:
5*2=10
3*3=9
following the same sequence:
2*6=12
therefore, the missing number is 12
(2,6,12)
Answer:
4/5
Step-by-step explanation:
1, 2 , 3 and 4 are factors of 12
so 4 out of 5
4/5 is the probability of getting factor of 12
Answer:
-3
Step-by-step explanation:
23=-5x+8
23-8=-5x
15=-5x
x=-3
Answer:
114
Step-by-step explanation:
The external angle measure is equal to the half of difference between the larger intercepted arc (5x-12) and the smaller intercepted arc (3x)
32 = (5x-12 -3x)/2
combine like terms in parenthesis and multiply both sides by 2
32·2 = 2x-12
multiply 32·2 = 64, and add 12 to both sides
64 + 12 = 2x
add 64+12 = 76, and divide both sides by 2 to isolate x
76/2 = x
38 = x
The measure of arc AB is 3x.
Substitute x for 38
Measure of arc AB = 3x = 3·38 = 114
