Question:

The ratio of girls girls to boys boys at a movie is 6:7. If there are 28 boys boys, how many girls girls are at the movie?

There are 24 girls at the movie.

Step-by-step explanation:

Given:

The ratio of girls to boys = 6:7

Number of boys  = 28

To Find:

Number of Girls at the movie = ?

Solution:

The Ratio of girls to boys = 6:7

girls : boys = 6 : 7

girls : 28 = 6 : 7

Now by cross multiplication

girls  = 24

both equations and proportions are better.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
