Russell's uncle buys a 7.5-pound bag of candy for Russell's birthday party. He puts 1 2 of the candy into a piñata. If Russell gets 1 5 of the candy from the piñata when it breaks open, how many pounds of candy does he get?

7.5/2 = 3.75

3.75/5 = .75

he gets .75 pounds of candy

5 x 14?

im new, sorry if this is wrong.

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
