Step-by-step explanation:

Let x represent the cost of an adult ticket and

Let y represent the cost of a child ticket.

Your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that 200 adults and 250 children will attend.

The equation that can be used to find what ticket prices to set in order to raise $3800 would be

200x + 250y = 3800

the answer is 24

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
