Answer:
8.22899353m
= 8m(round)
Step-by-step explanation:
14 * sin(36 degree) = 8.22899353
The equation of proportional situation is y = ax.
Therefore your answer is y = -2x + 14
S= number of small boxes
l= number of large boxes
equation 1: s+l=120
equation 2: 15s+45l=3300
solve by elimination, multiply equation 1 by -15.
-15(s+l=120) = -15s-15l=-1800 add to equation 2.
-15s+15s-15l+45l=-1800+3300 = 30l=1500
30l=1500 , l=50
s+l=120, s+50=120 --> s=70
