The airport security randomly selected 24 suitcases from in the security like. of these bags, they screened 7 suitcases. based on this information, what is the most reasonable prediction for the number of suitcases they will screen in a group of 144?

42 suitcases screened = x

Step-by-step explanation:

7/24 = x/144

7(144) = 24x

1,008 = 24x

42 = x

4x and 6y

im not sure though

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
