90%

Step-by-step explanation:

Total number of students= number of students who voted for the athlete + number of students who voted for the actor

=450+50

=500

% of students who voted for athletes= number of students who voted for athletes/total number of students*100

=450/500*100

=90%

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
