in the san diego zoo there are 4 times as many rabbits as foxes if there are 100 total rabbits and foxes in the zoo how many of each are there?

100 rabbits

25 foxes

Step-by-step explanation:

Because if there are 100 rabbits, we already know how many rabbits there are so, since we are trying to figure out how many foxes there are we take the 100 ÷ 4 = 25 foxes.

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
