Answer:
Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.
Step-by-step explanation:
Let suppose that Han's younger sister accelerates at constant rate, then, acceleration (
), measured in meters per square second, can be calculated by the following equation:
Where:
, 
- Initial and final times, measured in seconds.
, 
- Initial and final speeds, measured in meters per second.
If we know that 
, 
, 
and 
, the acceleration of the younger sister is:
Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.
Answer:
x = 5
Step-by-step explanation:
x + 3 = 8
x = 8 - 3
x = 5
To simplify the given equation, you want to combine like terms. Since both terms have x^8, we can add the coefficients and leave the x^8
3x^8-7x^8 (do 3-7)
=-4x^8 so the answer is C
Hope this helps
Answer:
4.7x
Step-by-step explanation:
3x + 1.7x
We can combine like terms
3x +1.7x = 4.7x
This is because:
3 + 1.7 = 4.7
4.7x
