Answer:
A. Infinitely many
Step-by-step explanation:
9x + 27 = 9(x + 2) + 9
Distribute on the right side.
9x + 27 = 9x + 18 + 9
Combine like terms on the right side.
9x + 27 = 9x + 27
Subtract 27 from both sides.
9x = 9x
Divide both sides by 9.
x = x
x = x is a true statement for every value of x. Therefore, any value you substitute in for x will make the original equation true. That means there is a infinite number of solutions.
Answer: A. Infinitely many
P (Not a 2) = P(2) + P(3) + P(4)
P(1) = 0.30
P(3) = 0.15
P(4) = 0.15
So,
P( Not a 2) = 0.30 + 0.15 + .15 = 0.60
So, the answer to this question is option D
No. the top right corner is the correct answer. Hope this helps!
