Tickets to see a movie cost $5 for children and $8 for adults. the equation 5x + 8y = 80 represents the number of children (x) and adults (y) who can see the movie with $80. if no adults see the movie, how many children can see the movie with $80? a) 13 b) 16 c) 6 d) 10

Step-by-step explanation:

The answer is B.16

Since the equation is 5x+8y=80

There are no parents so it equation will turn into 5x+8(0)=80, AKA, 5x=80

Using algebra, 5x=80 will x=80/5

which is 16

Step-by-step explanation:

5x+8y=80

y=0

5x=80

x=8-0/5=16

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

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
