x < -9 or x > 7

x + 1 < -8

x < -9

x + 1 > 8

x > 7

... when the inequality sign is facing the x, x is GREATER and it resembles an OR statement. I personally like to think of it as: greater than (greatOR than) = or statement; less than (less thAND) = and statement.

For the past 100 days hunter ran an average of 6.8 kilometers each day.(a)how many kilometers has he run in the last 100 days? (

myrzilka [38]

Answer:

(a) 680 km

(b) 680000 m

Step-by-step explanation:

(a) Distance run by hunter every day = 6.8 km

Total number of days under consideration = 100

So the total distance covered by the hunter = $\[6.8 * 100\]
$

= 680 km

The hunter ran 680 km in the last 100 days.

(b) Converting this value to meters:

1 km = 1000 m

=> 680 km = 680 * 1000 m

= 680000 m

The equivalent distance run by the hunter when converted to meters is 680000 meters.
