Justin's rice ball recipe uses 100 grams of rice to make 1 rice ball. Just has 700 grams of rice. How many rice balls can Justin make with 700 grams of rice

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

the answer is b.6

step-by-step explanation:

humans' internal body temperature is a great example of homeostasis. when an individual is healthy, his or her body temperature retains a temperature 98.6 degrees fahrenheit. the body can control temperature by making or releasing heat. the maintenance of healthy blood pressure is an example of homeostasis.

step-by-step explanation:

it will take 2 hours
