Answer:
It is 30.
Step-by-step explanation:
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.

The answer is Step 2.
The exponential equation is: 3ˣ⁺¹ = 15.
Step 1: log3ˣ⁺¹ = log15
Step 2: (x + 1) * log3 = log15
Step 3: x + 1 = log 15 / log 3
Step 4: x + 1 = 1.18 / 0.48
Step 5: x + 1 = 2.46
Step 6: x = 2.46 - 1
Step 7: x = 1.46

Answer:
Step-by-step explanation:
Here is how to get 9:
3x = 4(x - 2.25)
Solve 4(x - 2.25)
3x = 4x - 9
Move the variable to the left side and change it's sign
3x - 4x = -9
Combine like terms
-x = -9
change the signs
x = 9
There ya go! I hope this isn't too confusing!
