331 students went on a field trip 6 busses were filled and seven students traveled in cars. How many students were in each bus? select 2 equation to model this scenario

331-7=6b
331=6+7b
331-7b=6
331-b=7
331=6b+7
331=13b

if this is really you s much. i only have 3 points left and i have 2 questions to ask

x = 23.78

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
