Emma jogs 2 miles along the beach in
1
3
of an hour. If she travels at a constant rate, how far will she jog in an hour?

1. Use the known information to write a rate.

Emma’s rate:
2 miles
1
3
hours

2. Write an equivalent rate with a denominator of 1.

2(3) miles
1
3
(3) hours
=
?
1 hour

She will jog
miles.

Step-by-step explanation:

Emma jogs 2 miles along the beach in 1/3 of an hour. If she travels at a constant rate, how far will she jog in an hour?

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
