AB=48, DC=88
48+88=136
136÷2=68
Answer: LM=68
Remember that the length of the mid segment in a trapezoid is half the sum of the base lengths.
Answer:
Number of large boxes: 55
Number of small boxes:65
Step-by-step explanation:
Let be "l" the number of large boxes and "s" the number of small boxes.
Set up a system of equations:

Use the methof of elimination. Mulitply the first equation by -60 and add both equations. Then solve for "s":

Substitute s=65 into any of the original equations and solve for "l":

Answer:
2
Step-by-step explanation:
If the common difference is d we can write:
-5 + 9d = 13
9d = 18
d = 2
We have to find horizontal component of Mayosons velocity.
#a




#b
Here 2 vectors A=8 and B=2.5







The slope is rise over run.
Rise is the height and run is the length.
Slope = 6/18, which reduces to 1/3
