Patrick loaded 9 trucks every 27 minutes. At rate, how long will it take to load 6 trucks?

18 Minutes

Step-by-step explanation:

27 Minutes ÷ 9 Trucks = 3 Min per Truck

Therefore...

3 Minutes × 6 Trucks = 18 Min to load 6 Trucks

18

Step-by-step explanation:

27 mins load 9 trucks

and x min losd 6 trucks... so we do cross multiplication.. 6×27 ÷9

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
