Answer:
1. 8t
2. 510 + 6t
3. 510 - 2t
Step-by-step explanation:
1. Since the hare moves at a speed of 8 metres per second, the distance it moves from the starting line is d = speed × time = 8t
2. Since the rabbit moves at a speed of 6 metres per second, and gets a head start of 510 metres, the distance it moves from the starting line is d = 510 m + speed × time = 510 + 6t
3. The distance the tortoise is ahead of the hare is thus, distance moved by rabbit - distance moved by hare in time, t.
d' = 510 + 6t - 8t
= 510 - 2t
Answer:
-9y + 5x + 3
Step-by-step explanation:
-8y - (4x - 3) - y + 9x:
Group like terms = -(4x - 3) -8y - y + 9x
Add similar Elements - 8y - y + 9x = - (4x - 3) - 9y + 9x
Apply the distributive law: - (a - b) = -a + b = - (4x -3) = -4x + 3
= 4x + 3 - 9y + 9x
Group like terms = -9y - 4x + 9x + 3
Add similar Elements -4x + 9x = 5x
= -9y + 5x + 3
2 is even but is not composite. It is prime
