6. there are 90 seats in the school auditorium. the school had a sold out show of their play last weekend, and made $315. the cost of a ticket for an adult was $5.00 and the cost of a ticket for a child is $2.50. which system of equations could be used to determine the number of adults, a, and the number of children, c, that attended the showing of the movie? group of answer choices 2.5a+5c=90 2.5 a + 5 c = 90 a+c=315 a + c = 315 a+c=90 a + c = 90 5a+2.5c=315 5 a + 2.5 c = 315 5a+2.5c=90 5 a + 2.5 c = 90 a+c=315 a + c = 315 a+c=90 a + c = 90 2.5a+5c=315

50=33x+22

step-by-step explanation:

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
