The double number line shows that in 333 seconds an ostrich can run 636363 meters. Based on the ratio shown in the double number line, how far can an ostrich run in 555 seconds?

  105 m

Step-by-step explanation:

  distance/time = (63 m)/(3 s) = d/(5 s)

Multiplying by (5 s) gives the distance d as ...

  d = (5 s)(63 m)/(3 s) = 105 m

An ostrich can run 105 m in 5 seconds.

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
