Answer:
10
Step-by-step explanation:
First solve for x:
2x-3>12+x
x>15
And if this makes the statement true, than the statement would be false when x≤15
So then I guess G H and J are all answers
Answer:
Crosby is correct.
Step-by-step explanation:
You know this is true because if you plug in 3^2 * 3^3, you get 243.
If you type in 3^5, you get 243. If you type in 3^6, you get 729, which is not true.
Answer:
4 m/s downwards
Step-by-step explanation:
Velocity is given by dividing the distance by time taken to cover the diatance. Therefore, expressed as v=d/t
The distance is given as 24 m but the time given covers only half the distance. Therefore, the distance is 0.5*21=12 m
Time taken is given as 3 s
Substituting 12 m for d and 3 s for t then
V=12/3= 4 m/s
Velocity must have direction component hence velocity is 4 m/s downwards
