During the election for class president, 120 of the students voted for Lindsay, and 280 of the students voted for sharif. 400 Students voted in total. What percent of students voted for Lindsay?

x=200

Step-by-step explanation:

let 'x' represent the total number of students

0.40x of the students voted for Gerardo

0.35x of the students voted for Leandro

0.25x of the students voted for Juju

70 students voted for Leandro:

0.35x = 70

by solving we find:

x = 200 students

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
