Twin primes are pairs of prime numbers that have a difference of 2. for example, 11 and 13 are twin primes. what is the probability that the sum of a pair of twin primes is divisible by 12 if both primes in the pair are less than 100? express your answer as a common fraction

20

step-by-step explanation:

answer: idk

step-by-step explanation:

72 is the answer to this problem

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
