L+S=8, L=8-S
500L+200S=2200, using L from above in this equation gives you:
500(8-S)+200S=2200
4000-500S+200S=2200
4000-300S=2200
-300S=-1800
S=6, and since L=8-S:
L=2
So Rita bought 2 large packets and 6 small packets.
Answer:
Step-by-step explanation:
Umm what is your question u did not add it?
578.5 is your answer.
take 650 x .11 and you get 71.5.
take 650 - 71.5 = 578.5
They are adjacent because he share a vertex and a common side, and x=15° because 90°/(2+4)= 15
