Answer:
8
Step-by-step explanation:
The x intercept is when y = 0
x + 3(0) = 6
x = 6
So (6,0) and m = 6
the y intercept is when x = 0
0 + 3y = 6 Divide by 3
y = 6/3
y = 2
the y intercept is (0,2) and n = 2
Answer
m + n = 6 + 2 = 8
Hey there, Bulgogi!
The correct answer will be the first one since [I'm assuming] you know that to calculate the percentage of something, it's the amount of that something divided by the total amount but since only 30 students voted [12+18] multiplied by 100.
So, we are calculating the percentage on votes and 12 students voted for Candidate A so our Numerator will be 12 and our Denominator will be the total amount of student who voted, so 30 [or 12+18]
Once put into a fraction, we will get

which would be equals to 2/5 or 0.4. Now we multiply by 100 and we get a total of 40% for Candidate A.
Thank you for using Brainly.
See you soon!
