Hack:
x% of 100=x
88% of 100=88
times both sides by 6
88% of 600=6 times 88
88% of 600=528
answer is 528
Answer
The apple is traveling at 8 meters per second
Explanation
We have the equation that relates the kinetic energy with the velocty:

Then, to find thevelocity when the apple has 32, we replace K = 32 j:

Thus, the speed of the apple is 8meter per second

Answer:
Step-by-step explanation:
To properly apply the substitution method, it will be better for us to rearrange the system of equations to have similar variables on the same side


We can simply evaluate equation 1 to have

y = -20
From the first equation alone, we can evaluate the value of y as -20. This is because only one unknown is present in equation one, hence a single equation is sufficient enough to evaluate it. If to unknowns were present, the two equations would have been utilized to evaluate the solution.
