Answer:
cant see it
Step-by-step explanation:
just type it out
3-7, 4-8, 2-6, and 1-5 are all corresponding.
Since <span><span>secx</span>=<span>1<span>cosx</span></span></span>,
the first member becomes
<span><span><span><span>1<span>cosx</span></span>−1</span><span>1−<span>cosx</span></span></span>=<span><span><span>1−<span>cosx</span></span><span>cosx</span></span><span>1−<span>cosx</span></span></span>=<span>1<span>cosx</span></span>=<span>secx</span></span>.
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.
