Answers D. and E. are correct.
I think that B might also be correct, I hope This helps.
3/4x + 3 - 2x = -1/4 + 1/2x + 5
Put in terms of 4 as denominator
3/4x + 12/4 - 8/4x = -1/4 + 2/4x + 20/4
Combine like terms
-5/4x + 12/4 = 2/4x + 19/4
Simplify
12/4 = 7/4x + 19/4
-7/4 = 7/4x
x = -1 :)
Check:
3/4(-1) + 3 - 2(-1) = -1/4 + 1/2(-1) + 5
-3/4 + 3 + 2 = -1/4 - 1/2 + 5
-3/4 + 5 = -3/4 + 5
-3/4 = -3/4 :)
No because 24 hours would be from 3:20 to 3:20
Answer:
-8 just add them together
Answer:
hope it helps
Step-by-step explanation::
a) Consider a body having initial velocity 'u'. Suppose it is subjected to a uniform acceleration 'a' so that after time 't' its final velocity becomes 'v'. Now, from the definition of acceleration we know that:
Acceleration = Time taken Change in velocity or Acceleration = time taken
Final velocity- Initial velocity
So, a= t
v−u
at=v−u and, v=u + at
where v= final velocity of the body
u= initial velocity of the body
a= acceleration
and t= time taken
(b) Initial velocity, u=54km/h=15m/s
Final velocity, v=0m/s
Time, t=8s
Acceleration, a=?
a= t
v−u
= 8
