6 0

Answer:

x > -2

Step-by-step explanation:

3(1 – x) < 9

Divide each side by 3

3/3(1 – x) < 9/3

1-x < 3

Subtract 1 from each side

1-x-1 < 3-1

-x < 2

Multiply each side by 1, remembering to flip the inequality

-x*-1 > 2*-1

x > -2

Open circle at -2, line going to the right

Angel and Jayden were at track practice. The track is 2/5 kilometers around.  Angel ran 1 lap in 2 minutes.  Jayden ran 3 laps

choli [55]

Answer:

6/25 km in 1 min; or 0.24 km/min

Step-by-step explanation:

The info about Angel is not necessary.

Jayden runs 3 laps in 5 mins

Each lap is 2/5 km, so Jayden runs 3 x (2/5 km) in 5 min = 6/5 km in 5 min.

Distance = rate x time

6/5 km = rate (5 min)

We want to isolate r (rate), so divide both sides by 5 min

6/5 km ÷ 5 min = r

6/5 km (1/5 min) = r

6/25 km/min = r (notice how the units worked out correctly to km/min)

So, Jayden runs 6/25 km in 1 min.
