Answer:
30 students (30 total voters)
Step-by-step explanation:
Let s represent the number of students in the class. Evan earned 80% of these votes, which came to 24 votes. Symbolically, we have:
24 votes
0.80s = 24 votes. Therefore, s = total number of voters = ---------------- = 30 voters 0.8
The total number of students (voters) in his class was 30.

Answer:
x = - 9, x = - 3
Step-by-step explanation:
Given
x² + 12x + 27 = 0
To factorise the quadratic
Consider the factors of the constant term (+ 27) which sum to give the coefficient of the x- term (+ 12)
The factors are + 9 and + 3, since
9 × 3 = 27 and 9 + 3 = 12, hence
(x + 9)(x + 3) = 0
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x + 3 = 0 ⇒ x = - 3
Answer:
C
Step-by-step explanation:
The parabola faces downwards, so "a" will be negative. Using this information, we cancel out answer choice D and A. However in answer choice B, it uses y^2 instead of x^2 which is incorrect. Then, the only option you have left is C which is correct.
