The sum of a number is represented by X. So X and 6.4 is X+6.4. Is less than 9.9, so <9.9. You get X+6.4<9.9.
Answer:
50%
Step-by-step explanation:
There are 8 tiles on the spinner, 4 of which are red.
4/8 = 1/2 - 50%
There is a 50% chance that the spinner will land on red.
17 + 2 = 19 km is 1/2 of the total length, that is,
19 = (1/2)h
(1/2)h = 19 multiply both sides by 2
h = 2*19
h = 38 km
The total length in kilometers is 38 km
