Assuming this is around the origin:
To find the rotation by 90 degrees, it would be (y, -x) (Assuming that the x and y are both variables and number figures)
So therefore, (5, 2) would become (2, -5).
I hope this helped! :)
Camille spent 22 minutes and 30 seconds opening presents.
Since Camille had a very fun birthday party with lots of friends and family attending, and the party lasted for 3 hours, and she and her friends played games for 3/8 of the time, ate pizza and cake for 50% of the time , and spent the remainder of the time opening presents, to determine the amount of time spent opening presents the following calculation must be performed, posing the following linear equation:
Total time - time spent on other activities = time spent opening presents
- 3 - (3 x 3/8) - (3 x 0.5) = X
- 3 - 1.125 - 1.5 = X
- 3 - 2.625 = X
- 0.375 = X
- 1 = 60
- 0.375 = X
- 0.375 x 60 = X
- 22.5 = X
Therefore, Camille spent 22 minutes and 30 seconds opening presents.

sophie has 12 blunt pencils.
The answer is 10.
Parallel lines show similar triangles showing us that (2x + 6)/10 = (x+6)/8. Solving this equation for x gives us x = 2. Plugging this into 2x + 6 gives us 2(2) + 6 = 10.
0.3x = 0.2 - 0.2x
0.5x = 0.2
x =0.2/0.5 = 2/5
