Answer:
5 erasers.
Step-by-step explanation:
0.35e + 0.15p = 2.80
e + p = 12
e = 12 - p
0.35(12 - p) + 0.15p = 2.80
4.2 - 0.35p + 0.15p = 2.80
4.2 - 0.2p = 2.80
-0.2p = -1.4
-0.2p/-0.2p = -1.4/-0.2
p = 7
e = 12 - 7
e = 5
Angle Q will have the same measurement as it did before, 30°.
Just because the angle is rotated shouldn't change its angle measure.
