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

Step-by-step explanation:
M=3
-EXPLANATION-
Slope=rise over run(rise/run)
I used the points (-1,-6) and (2,3)
To solve you will use this formula: m=y₂−y₁/x₂−x₁
3=y2
2=y1
-6=x2
-1=x1
——————-
Set it up like so:
3- -6/2- -1
3- (-6)= 9
2- (-1)=3
9/3
9 divided by 3 is 3, making your slope(m) 3
