Solution
For this case we have the following equation given:
And we can distribute the terms first ans we got:

Then we can aggrupate the terms like this:

Then we can solve for n like this:

5n =15
n = 15/5= 3
Answer: 5h represents the number of hours Rob actually spent on the project.
Step-by-step explanation:
Let Rob planned that he will spend x hours in his project.
According to the question,
He spent 25% more time on his project than he planned.
That is, his actual time = x + 25% of x = 125% of x
Again according to the question,
He spent an extra h hours on his project.
That is, 25% of x = h


x = 4h
Thus, his actual time = 125% of x = 125% of 4h =
= 5h
Which is the required expression.
I won't! the answer is 5/12 and that is also its simplest form! I hope that this helps you and i also hope that you get an A+!!♥
Answer:
(-8, 135°)
Step-by-step explanation:
(8, -45°) has magnitude 8 and direction -45°.
If we add 180° to the direction and change the sign of the magnitude, we'll have the same point.
(-8, -45° + 180°) = (-8, 135°)
