Mrs. Sweet made a pie. She gave​ ½ ​of the pie to her son and ​¼ ​of the pie to her daughter. How much pie did she give away altogether? Put your answer in the box. Show your work.

she gave away 3/4 of the pie.

explanation: add 1/2 and 1/3 you can change the 1/2 to 2/4 then add the 1/4 which makes it 3/4

Step-by-step explanation:

3/4

Step-by-step explanation:

1/2=2/4

2/4+1/4=3/4

she gave away 3/4 of her pie to her kids

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
