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

16

Step-by-step explanation:

If there are no adults watching the movie, we can take out y from the equation altogether, so that only leaves 5x=80, simply divide 80 by 5, in which case you get 16. Plug in 16 as x to get 5(16)=80. Do the math to check, and you get 16 children can watch the movie for 80$.

answer: ask

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
