To solve for x, the first thing to do is to distribute the 4 to (x-2). When you do this, you should get 4x-8=4x+10
Then, subtract 4x from both sides and then you are left with -8=10. Because -8 is not equal to 10, meaning the equation you are left with is not a true statement, the answer to this would be that there are no real solutions.
The answer is A. Subtract the five on both sides and you end up with A :)
Let n = 10, p = 0.897, x = 10 Computing for the probability that 10 students will graduate from high school, we use the formula P (X) = 10 ! / (0 ! 10 !) (0.897) 10 (0.103) 0 = 0.337
Therefore, 0.337 is the probability that 10 students will graduate from high school
