The serving size for a toddlers daily vitamin c is 3/4 cup of orange juice. if there are 2 1/4 cups of orange juice how many servings of vitamin c are there for a toddler

Three servings

To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .

2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4

9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings

Step-by-step explanation:

the answer is b

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
